Heart Atria
The chambers of the heart, to which the BLOOD returns from the circulation.
Echocardiography, Doppler
Measurement of intracardiac blood flow using an M-mode and/or two-dimensional (2-D) echocardiogram while simultaneously recording the spectrum of the audible Doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells.
Atrial Fibrillation
Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.

A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.
Hemodynamics
The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.

A comparison of an A1 adenosine receptor agonist (CVT-510) with diltiazem for slowing of AV nodal conduction in guinea-pig. (1/734)

1. The purpose of this study was to compare the pharmacological properties (i.e. the AV nodal depressant, vasodilator, and inotropic effects) of two AV nodal blocking agents belonging to different drug classes; a novel A1 adenosine receptor (A1 receptor) agonist, N-(3(R)-tetrahydrofuranyl)-6-aminopurine riboside (CVT-510), and the prototypical calcium channel blocker diltiazem. 2. In the atrial-paced isolated heart, CVT-510 was approximately 5 fold more potent to prolong the stimulus-to-His bundle (S-H interval), a measure of slowing AV nodal conduction (EC50 = 41 nM) than to increase coronary conductance (EC50 = 200 nM). At concentrations of CVT-510 (40 nM) and diltiazem (1 microM) that caused equal prolongation of S-H interval (approximately 10 ms), diltiazem, but not CVT-510, significantly reduced left ventricular developed pressure (LVP) and markedly increased coronary conductance. CVT-510 shortened atrial (EC50 = 73 nM) but not the ventricular monophasic action potentials (MAP). 3. In atrial-paced anaesthetized guinea-pigs, intravenous infusions of CVT-510 and diltiazem caused nearly equal prolongations of P-R interval. However, diltiazem, but not CVT-510, significantly reduced mean arterial blood pressure. 4. Both CVT-510 and diltiazem prolonged S-H interval, i.e., slowed AV nodal conduction. However, the A1 receptor-selective agonist CVT-510 did so without causing the negative inotropic, vasodilator, and hypotensive effects associated with diltiazem. Because CVT-510 did not affect the ventricular action potential, it is unlikely that this agonist will have a proarrythmic action in ventricular myocardium.  (+info)

Identification and characterization of multiple subtypes of muscarinic acetylcholine receptors and their physiological functions in canine hearts. (2/734)

M2 receptors have long been believed to be the only functional subtype of muscarinic acetylcholine receptor (mAChR) in the heart, although recent studies have provided evidence for the presence of other subtypes. We performed a detailed study to clarify this issue. In the presence of tetramethylammonium (1 microM to 10 mM), a novel K+ current with both delayed rectifying and inward rectifying properties (IKTMA) was activated in single canine atrial myocytes. 4-Aminopyridine (0.05-2 mM) also induced a K+ current (IK4AP) with characteristics similar to but distinct from those of IKTMA. Both IKTMA and IK4AP were abolished by 1 microM atropine. IK4AP, but not IKTMA, was minimized by treatment with pertussis toxin. IKTMA was markedly decreased by 4-diphenylacetoxy-N-methylpiperidine methiodide (a selective antagonist for M3 subtype) but was not altered by pirenzepine (for M1), methoctramine (for M2), and tropicamide (for M4). Tropicamide substantially reduced IK4AP, but the antagonists for other mAChR subtypes had no effects on IK4AP. By comparison, IKACh (ACh-induced K+ current) was significantly depressed by methoctramine but was unaltered by other antagonists. Results from displacement binding of [methyl-3H]N-scopolamine methyl chloride with pirenzepine, methoctramine, 4-diphenylacetoxy-N-methylpiperidine methiodide, or tropicamide revealed the coexistence of multiple mAChR subtypes in canine atrium. Cloning of cDNA fragments and detection of mRNAs coding for M2, M3, and M4 provided further supporting evidence. Our results suggest that 1) multiple subtypes of mAChRs (M2/M3/M4) coexist in the dog heart and 2) different subtypes of mAChRs are coupled to different K+ channels. Our findings represent the first functional evidence for the physiological role of cardiac M3 and M4 receptors.  (+info)

Regional differences in the recovery course of tachycardia-induced changes of atrial electrophysiological properties. (3/734)

BACKGROUND: Regional differences in recovery of tachycardia-induced changes of atrial electrophysiological properties have not been well studied. METHODS AND RESULTS: In the control group (5 dogs), atrial effective refractory period (AERP) and inducibility of atrial fibrillation (AF) were assessed before and every 4 hours for 48 hours after complete atrioventricular junction (AVJ) ablation with 8-week VVI pacing. In experimental group 1 (15 dogs), AERP and inducibility of AF were assessed before and after complete AVJ ablation with 8-week rapid right atrial (RA) pacing (780 bpm) and VVI pacing. In experimental group 2 (7 dogs), AERP and inducibility of AF were assessed before and after 8-week rapid left atrial (LA) pacing and VVI pacing. AERP and inducibility and duration of AF were obtained from 7 epicardial sites. In the control group, atrial electrophysiological properties obtained immediately and during 48-hour measurements after pacing did not show any change. In the 2 experimental groups, recovery of atrial electrophysiological properties included a progressive recovery of AERP shortening, recovery of AERP maladaptation, and decrease of duration and episodes of reinduced AF. However, recovery of shortening and maladaptation of AERP and inducibility of AF was slower at the LA than at the RA and Bachmann's bundle. CONCLUSIONS: The LA had a slower recovery of tachycardia-induced changes of atrial electrophysiological properties, and this might play a critical role in initiation of AF.  (+info)

Rate-dependent blockade of a potassium current in human atrium by the antihistamine loratadine. (4/734)

The antihistamine loratadine is widely prescribed for the treatment of symptoms associated with allergies. Although generally believed to be free of adverse cardiac effects, there are a number of recent reports suggesting that loratadine use may be associated with arrhythmias, in particular atrial arrhythmias. Nothing is known regarding the potassium channel blocking properties of loratadine in human cardiac cells. Using the whole-cell patch clamp technique, the effects of loratadine on the transient outward K current (Ito), sustained current (Isus), and current measured at -100 mV (IK1 and Ins), the major inward and outward potassium currents present in human atrial myocytes, were examined in order to provide a possible molecular mechanism for the observed atrial arrhythmias reported with loratadine use. Loratadine rate-dependently inhibited Ito at therapeutic concentrations with 10 nM loratadine reducing Ito amplitude at a pacing rate of 2 Hz by 34.9+/-6.0%. In contrast, loratadine had no effect on either Isus or current measured at -100 mV. These results may provide a possible mechanism for the incidences of supraventricular arrhythmias reported with the use of loratadine.  (+info)

Inhibitory effects of aprindine on the delayed rectifier K+ current and the muscarinic acetylcholine receptor-operated K+ current in guinea-pig atrial cells. (5/734)

In order to clarify the mechanisms by which the class Ib antiarrhythmic drug aprindine shows efficacy against atrial fibrillation (AF), we examined the effects of the drug on the repolarizing K+ currents in guinea-pig atrial cells by use of patch-clamp techniques. We also evaluated the effects of aprindine on experimental AF in isolated guinea-pig hearts. Aprindine (3 microM) inhibited the delayed rectifier K+ current (IK) with little influence on the inward rectifier K+ current (IK1) or the Ca2+ current. Electrophysiological analyses including the envelope of tails test revealed that aprindine preferentially inhibits IKr (rapidly activating component) but not IKs (slowly activating component). The muscarinic acetylcholine receptor-operated K+ current (IK.ACh) was activated by the extracellular application of carbachol (1 microM) or by the intracellular loading of GTPgammaS. Aprindine inhibited the carbachol- and GTPgammaS-induced IK.ACh with the IC50 values of 0.4 and 2.5 microM, respectively. In atrial cells stimulated at 0.2 Hz, aprindine (3 microM) per se prolonged the action potential duration (APD) by 50+/-4%. The drug also reversed the carbachol-induced action potential shortening in a concentration-dependent manner. In isolated hearts, perfusion of carbachol (1 microM) shortened monophasic action potential (MAP) and effective refractory period (ERP), and lowered atrial fibrillation threshold. Addition of aprindine (3 microM) inhibited the induction of AF by prolonging MAP and ERP. We conclude the efficacy of aprindine against AF may be at least in part explained by its inhibitory effects on IKr and IK.ACh.  (+info)

Aryl propanolamines: comparison of activity at human beta3 receptors, rat beta3 receptors and rat atrial receptors mediating tachycardia. (6/734)

1. The in vitro activity of four aryl propanolamines was compared to two prototypic beta3 receptor agonists, CGP 12177 and CL316243 at the human beta3 receptor, the rat beta3 receptor in the stomach fundus and receptors mediating atrial tachycardia. 2. L-739,574 was the most potent (EC50 = 9 nM) and selective agonist at the human beta3 receptor with high maximal response (74% of the maximal response to isoproterenol). 3. A phenol-biaryl ether analogue possessed modest affinity for the human beta3 receptor (EC50 = 246 nM), but was highly efficacious with a maximal response 82% of the maximal response to isoproterenol. The other derivatives were intermediate in potency with low maximal responses. 4. These agonists at the human beta3 receptor did not activate the rat beta3 receptor in the rat stomach fundus. In fact, the aryl propanolamines (10(-6) M) inhibited CL316243-induced activation of the rat beta3 receptor. Thus, agonist activity at the human beta3 receptor translated into antagonist activity at the rat beta3 receptor. 5. L739,574 and the phenol biaryl ether increased heart rate via beta1 receptors. 6. Although CGP12177 produced atrial tachycardia, neither the indole sulphonamide nor biphenyl biaryl ether did, although both had high affinity for the human beta3 receptor. Thus, the atrial tachycardic receptor was not identical to the human beta3 receptor. 7. These studies (a) characterized four aryl propanolamines with high affinity at the human beta3 receptor, (b) found that they were antagonists at the rat beta3 receptor, an observation with profound implications for in vivo rat data, and (c) established that the rodent atrial non-beta1, beta2 or beta3 tachycardic receptor was also unrelated to the human beta3 receptor.  (+info)

Altered kinetics of contraction of mouse atrial myocytes expressing ventricular myosin regulatory light chain. (7/734)

To investigate the role of myosin regulatory light chain isoforms as a determinant of the kinetics of cardiac contraction, unloaded shortening velocity was determined by the slack-test method in skinned wild-type murine atrial cells and transgenic cells expressing ventricular regulatory light chain (MLC2v). Transgenic mice were generated using a 4.5-kb fragment of the murine alpha-myosin heavy chain promoter to drive high levels of MLC2v expression in the atrium. Velocity of unloaded shortening was determined at 15 degrees C in maximally activating Ca2+ solution (pCa 4.5) containing (in mmol/l) 7 EGTA, 1 free Mg2+, 4 MgATP, 14.5 creatine phosphate, and 20 imidazole (ionic strength 180 mmol/l, pH 7.0). Compared with the wild type (n = 10), the unloaded shortening velocity of MLC2v-expressing transgenic murine atrial cells (n = 10) was significantly greater (3.88 +/- 1.19 vs. 2.51 +/- 1.08 muscle lengths/s, P < 0.05). These results provide evidence that myosin light chain 2 regulates cross-bridge cycling rate. The faster rate of cycling in the presence of MLC2v suggests that the MLC2v isoform may contribute to the greater power-generating capabilities of the ventricle compared with the atrium.  (+info)

Mapping of atrial activation with a noncontact, multielectrode catheter in dogs. (8/734)

BACKGROUND: Endocardial mapping of sustained arrhythmias has traditionally been performed with a roving diagnostic catheter. Although this approach is adequate for many tachyarrhythmias, it has limitations. The purpose of this study was to evaluate a novel noncontact mapping system for assessing atrial tachyarrhythmias. METHODS AND RESULTS: The mapping system consists of a 9F multielectrode-array balloon catheter that has 64 active electrodes and ring electrodes for emitting a locator signal. The locator signal was used to construct a 3-dimensional right atrial map; it was independently validated and was highly accurate. Virtual electrograms were calculated at 3360 endocardial sites in the right atrium. We evaluated right atrial activation by positioning the balloon catheter in the mid right atrium via a femoral venous approach. Experiments were performed on 12 normal mongrel dogs. The mean correlation coefficient between contact and virtual electrograms was 0.80+/-0.12 during sinus rhythm. Fifty episodes of atrial flutter induced in 11 animals were evaluated. In the majority of experiments, complete or almost complete reentrant circuits could be identified within the right atrium. Mean correlation coefficient between virtual and contact electrograms was 0.85+/-0.17 in atrial flutter. One hundred fifty-six episodes of pacing-induced atrial fibrillation were evaluated in 11 animals. Several distinct patterns of right atrial activation were seen, including single-activation wave fronts and multiple simultaneous-activation wave fronts. Mean correlation coefficient between virtual and contact electrograms during atrial fibrillation was 0.81+/-0.18. The accuracy of electrogram reconstruction was lower at sites >4.0 cm from the balloon center and at sites with a high spatial complexity of electrical activation. CONCLUSIONS: This novel noncontact mapping system can evaluate conduction patterns during sinus rhythm, demonstrate reentry during atrial flutter, and describe right atrial activation during atrial fibrillation. The accuracy of electrogram reconstruction was good at sites <4.0 cm from the balloon center, and thus the system has the ability to perform high-resolution multisite mapping of atrial tachyarrhythmias in vivo.  (+info)

Abstract 13613: Identification of a Novel Somatic Mutation in Sarcolipin Gene in Human Fetal Atrial Standstill | CirculationAbstract 13613: Identification of a Novel Somatic Mutation in Sarcolipin Gene in Human Fetal Atrial Standstill | Circulation
Sarcolipin (SLN), a key regulator of sarcoplasmic reticulum Ca2+ ATPase (SERCA) plays an important role in atrial Ca2+ homeostasis and therefore suggested as a possible candidate for genetic cause of atrial arrhythmias. The aim of this study was to find if the SLN gene has a causative role in human atrial standstill, a rare lethal disorder of atrial musculature. Genomic DNA from formalin fixed atrial tissue and fibroblast from deceased newborn with atrial standstill were used as templates in PCR reaction to amplify the coding exon of SLN and screened for mutation. DNA sequencing identified ATG → ATA transition mutation at the translation initiation site in 20% of clones from atrial DNA. There were no coding region mutations identified in clones obtained from fibroblast tissues. To validate our findings, we designed mutant specific PCR screening method and amplified the genomic DNA from control atria and atria and fibroblast tissues of fetal atrial standstill. PCR amplification occurs only with ...

Results Atrial trabeculae harvested from diabetic (N=13 patients) and non-diabetic control patients (N=20 patients) were demonstrated to recover 24.5%±2.4% and 29.3%±1.3% of baseline contractile function, respectively. Prior treatment of patients with RIPC1 increased the recovery of function in both non-diabetic (50.4%±1.9%; p,0.05) and diabetic (41.6%±1.9%; p,0.05) patients. Interestingly, the stronger RIPC2 stimulus resulted in a greater recovery of function in both non-diabetic (59.3%±1.9%; p,0.05) and diabetic (50.7%±2.1%; p,0.05) patients. As a positive control direct hypoxic preconditioning (HPC) of atrial trabeculae also improved the recovery of function (56.4%±1.8% with HPC vs 27.5%±1.7% in control; N=10 patients; p,0.05). The administration of the MEK-Erk1/2 inhibitors U0126 and PD98059 at the onset of reperfusion abrogated the protective effect in both non-diabetic (30.9%±0.8% U0126 and 31.3%±0.8% PD98059; p,0.05) and diabetic (28.6%±0.9% U0126 and 30.0%±1.2% PD98059; ...

Effect of Chronic Right Atrial Stretch on Atrial Electrical Remodeling in Patients With an Atrial Septal Defect | CirculationEffect of Chronic Right Atrial Stretch on Atrial Electrical Remodeling in Patients With an Atrial Septal Defect | Circulation
The natural history of adults with an atrial septal defect (ASD) and chronic right atrial (RA) volume overload is characterized by an increased risk for the development of atrial arrhythmias that appears to be minimally altered by ASD closure.1 Although surgical lines of block may form the substrate for scar-related atrial macroreentry after surgical ASD repair,2 there is limited information concerning the impact of chronic RA stretch and volume overload on atrial electrophysiology in ASD patients.. Animal studies of chronic atrial enlargement have demonstrated an increased vulnerability to atrial arrhythmias,3,4 and atrial electrical remodeling (ER) has been described in response to chronic atrial stretch.3,5 Although initial studies of atrial ER focused on tachycardia-induced changes in atrial refractoriness for the promotion of atrial fibrillation (AF),6 more recent studies concerning chronic atrial stretch and ER have emphasized the contribution of heterogeneous disturbances in atrial ...

Atrial Function in Patients Undergoing CRT | JACC: Cardiovascular ImagingAtrial Function in Patients Undergoing CRT | JACC: Cardiovascular Imaging
We read with great interest the paper by Carluccio et al. (1) regarding the impact of left ventricular (LV) remodeling on the response to cardiac resynchronization therapy (CRT). In this elegant study, the authors performed a comprehensive assessment of LV function, showing that extensive LV remodeling at baseline is associated with poor improvement after CRT.. We wish to raise an essential issue, which may be of keen interest to the readers.. In recent years, there has been growing interest in the potential impact of CRT on atrial function, but the state of knowledge in this field is still controversial and unsettled (2-4). In the paper by Carluccio et al. (1) several baseline data concerning atrial function are presented (left atrial volume index and mitral regurgitation severity), but unfortunately there is no information related to CRT response. We believe that their excellent echocardiographic data could also be useful to better understand another debated issue (i.e., the effect of CRT on ...

N2 - Objective: The purpose of this study was to examine the presence and frequency of antegrade late diastolic arterial blood flow (ALDAF) in the fetus and to determine its contribution to cardiac output. Study Design: We evaluated the presence of ALDAF in 457 fetal and 21 postnatal echocardiograms. The timing of ALDAF to the ventricular systolic Doppler recording (ALDAF-V) was compared with the mechanical atrioventricular interval and, in neonates, the electrical PR interval. Velocity time integrals of ALDAF and the ventricular systolic Doppler signals were measured, and the percent contribution of ALDAF was calculated. Results: ALDAF was ...

Several anti-arrhythmic agents, which are used in treatment of AF, exist. However, the efficacy of these drugs still can be improved. Furthermore, some of them are associated with a wide range of adverse side effects. Therefore, the mechanisms of action of these agents have to be better understood and still can be optimized.. Dronedarone is an anti-arrhythmic agent used in the treatment of AF by maintaining sinus rhythm. It is a derivative of amiodarone and has been developed to reduce the side effects as e.g. thyroid toxicity of its precursor compound.. The aim of this work is to integrate the effects of dronedarone into a model of atrial electrophysiology. In this way, the mechanism of action, i.e. the anti-arrhythmic effects of this agent should be better understood. In previous work, the effects of amiodarone were already integrated into an atrial cell model. Finally, a comparison of both agents and their impact on healthy and electrically remodeled tissue shall be carried out. ...

Introduction: The development of improved diagnosis, management, and treatment strategies for human atrial fibrillation (AF) is a significant and important challenge in order to improve quality of life for millions and reduce the substantial social-economic costs of the condition. As a complex condition demonstrating high variability and relation to other cardiac conditions, the study of AF requires approaches from multiple disciplines including single-cell experimental electrophysiology and computational modeling. Models of human atrial cells are less well parameterized than those of the human ventricle or other mammal species, largely due to the inherent challenges in patch clamping human atrial cells. Such challenges include, frequently, unphysiologically depolarized resting potentials and thus injection of a compensatory hyperpolarizing current, as well as detecting certain ion currents which may be disrupted by the cell isolation process. The aim of this study was to develop a laboratory specific
