In contrast to the atrial switch procedures (Mustard and Senning operation), the ASO has the advantage of the maintenance of sinus rhythm, utilization of the left ventricle as the systemic ventricle and the mitral valve as the systemic atrioventricular valve 3) . (e-cep.org)
Atrial fibrillation is a type of abnormal heart rhythm characterized by an irregular and rapid heartbeat. (ecgedu.com)
Since there is no functioning connection between the atria and the ventricles, there are two independent rhythms (an atrial rhythm and a ventricular rhythm) superimposed on one rhythm strip. (ecgedu.com)
Junctional1
An AV-junctional rhythm , or atrioventricular nodal bradycardia, is usually caused by the absence of the electrical impulse from the sinus node . (wikipedia.org)
AIVR6
Accelerated idioventricular rhythm (AIVR) was first described by Sir Thomas Lewis in 1910. (medscape.com)
[ 1 ] AIVR is currently defined as an enhanced ectopic ventricular rhythm with at least 3 consecutive ventricular beats, which is faster than normal intrinsic ventricular escape rhythm (≤40 bpm), but slower than ventricular tachycardia (at least 100-120 bpm). (medscape.com)
AIVR is generally a transient rhythm, rarely causing hemodynamic instability and rarely requiring treatment. (medscape.com)
[ 8 ] When the enhanced automaticity in His-Purkinje fiber or myocardium surpasses that of sinus node, AIVR manifests as the dominant rhythm of the heart. (medscape.com)
Accelerated idioventricular rhythm (AIVR) can occur in people with and without apparent heart diseases. (medscape.com)
The patient was able to intermittently go into sinus rhythm with vagal maneuvers. (emra.org)
Sinus bradycardia is a sinus rhythm of less than 60 BPM. (wikipedia.org)
Large multi-institutional placebo-controlled, double-blinded trials in human cardiology (notably the CAST trials) have shown that although ventricular antiarrhythmic drugs can eliminate the arrhythmia and restore sinus rhythm, the human patients whose rhythm was improved this way died in significantly greater numbers than did the untreated (placebo) patients. (vin.com)
Atrioventricular2
Accelerated idioventricular rhythm Monomorphic ventricular tachycardia Polymorphic ventricular tachycardia Ventricular fibrillation Torsades de pointes Arrhythmogenic right ventricular dysplasia Re-entry ventricular arrhythmia These are also known as AV blocks, because the vast majority of them arise from pathology at the atrioventricular node. (wikipedia.org)
Idioventricular rhythm , also known as atrioventricular bradycardia or ventricular escape rhythm, is a heart rate of less than 50 BPM. (wikipedia.org)
Polymorphic1
Historically, treating ventricular arrhythmias often was presented as a straightforward proposition: "If the rhythm is VT, or if there are more than 10/15/20/30 VPCs each minute (depending on the author), or if the rhythm has other 'criteria of malignancy' (e.g., polymorphic VT), then treatment must be instituted in order to prevent deterioration to even worse arrhythmias or cardiac arrest. (vin.com)
Arrhythmia4
In postural tachycardia syndrome/orthostatic intolerance patients, arrhythmia was detected on 15% of 332 ambulatory rhythm monitors. (cambridge.org)
In syncope patients, arrhythmia was detected on 16% of 157 ambulatory rhythm monitors, not significantly different from the postural tachycardia syndrome/orthostatic intolerance group. (cambridge.org)
A dog with an accelerated idioventricular rhythm, where all QRS complexes are wide and bizarre in shape and there is no A-V relationship, at a rate of 110 beats per minute, may have an ECG that is initially alarming (looks like "slow VT") but in fact be well-perfused and normotensive, and have none of its clinical signs due to the arrhythmia. (vin.com)

Premature1
Exercise generally abolishes premature beats in normal hearts, and the rhythm becomes regular. (health.am)
Cardiac4
There is sparse literature on cardiac arrhythmias and the utility of ambulatory rhythm monitoring in patients with postural tachycardia syndrome and orthostatic intolerance. (cambridge.org)
This retrospective descriptive study examined the frequency of cardiac arrhythmias, as detected by ambulatory rhythm monitoring, in children with postural tachycardia syndrome/orthostatic intolerance or syncope who were seen at the Children's National Hospital Electrophysiology Clinic between January 2001 and December 2020. (cambridge.org)
The ventricular muscle twitches randomly rather than contracting in a co-ordinated fashion (from the apex of the heart to the outflow of the ventricles), and so the ventricles fail to pump blood around the body - because of this, it is classified as a cardiac arrest rhythm, and patients in V-fib should be treated with cardiopulmonary resuscitation (CPR) and prompt defibrillation . (mdwiki.org)
Some clinicians may attempt to defibrillate fine V-fib in the hope that it can be reverted to a cardiac rhythm compatible with life, whereas others will deliver CPR and sometimes drugs as described in the advanced cardiac life support protocols in an attempt to increase its amplitude and the odds of successful defibrillation. (mdwiki.org)
Abnormal heart rhythm3
Complete heart block is a type of abnormal heart rhythm typically characterized by a slow or absent heartbeat. (ecgedu.com)
Ventricular tachycardia is a type of abnormal heart rhythm characterized by a rapid heartbeat. (ecgedu.com)
Ventricular fibrillation ( V-fib or VF ) is an abnormal heart rhythm in which the ventricles of the heart quiver instead of pumping normally. (mdwiki.org)
LBBB1
Use the modified Sgarbossa criteria to diagnose OMI in LBBB, ventricular paced rhythm, and generally all other significantly wide QRS complex morphologies. (blogspot.com)
Reperfusion1
[ 7 ] Ischemia, reperfusion, hypoxia, drugs, and electrolyte abnormalities can all accelerate the phase 4 action potential depolarization rates in His-Purkinje fiber and myocardium, leading to faster spontaneous cell depolarization (enhanced automaticity). (medscape.com)
Regimen1
The safety and efficacy of this accelerated infusion of Alteplase regimen has only been investigated with concomitant administration of heparin and aspirin . (wikidoc.org)
Beats1
[2] In 1889 J A McWilliam reported his experiments of application of an electrical impulse to the human heart in asystole to cause a ventricular contraction and that a heart rhythm of 60-70 beats per minute could be evoked by impulses applied at spacings equal to 60-70/minute. (wikidoc.org)
Occur1
The usual mechanism is reentry, but abnormally triggered rhythms occur. (health.am)
Acute1
Obviously, having 120 leads (which has been tested in several studies on acute myocardial infarction ) would improve sensitivity for many conditions, at the expense of specificity and certainly feasibility. (ecgwaves.com)
Electrocardiogram3
A number of tests can help with diagnosis, including an electrocardiogram (ECG) and Holter monitor. (wikipedia.org)
EKG Technicians administer a variety of cardiovascular tests, including the electrocardiogram ( EKG ) which measures the electrical activity of your heart through small electrodes. (kingexams.com)
An electrocardiogram (ECG) is a noninvasive test that measures the electrical activity of the heart. (ecgedu.com)
Interpretation1
The major components to observe in the interpretation of an ECG are the rhythm, rate, axis and morphology, as shown by the P wave, P-R interval, QRS complex, ST segment, T wave and Q-T interval (see box). (clinicalgate.com)
Abnormalities1
In 25% of patients, such rhythm abnormalities manifest within the first 24 hours. (medscape.com)
Patients4
And EKG technicians with advanced training may administer "stress tests" which involve testing patients while they use a treadmill. (kingexams.com)
They also prepare patients for their tests and keep them as calm as possible during the procedures so the results are as accurate as they can be. (kingexams.com)
Knowing the prevalence and types of arrhythmias in dysautonomia patients could influence the decision to pursue ambulatory rhythm monitoring and ultimately guide therapy. (cambridge.org)
Left untreated, ventricular fibrillation is rapidly fatal as the vital organs of the body, including the heart, are starved of oxygen, and as a result patients in this rhythm will not be conscious or responsive to stimuli. (mdwiki.org)
Responsive1
As the name verapamil-sensitive VT suggests, this rhythm is very responsive to verapamil, typically dosed 2.5-5 mg IV every 15-30 minutes. (emra.org)
Restore1
Medications for a fast heart rate may include beta blockers, or antiarrhythmic agents such as procainamide, which attempt to restore a normal heart rhythm. (wikipedia.org)
Normal1
It is not necessary to describe the ECG in the traditional and pedantic way, opening with the rate, rhythm and axis and then going on to describe the rest if they are normal. (clinicalgate.com)
Edit1
Once the tests are administered, EKG technicians edit the data and highlight anomalies and areas of concern. (kingexams.com)
Diagnose1
This disorder is easy to diagnose with a simple blood test and the ST segment elevations resolve after normalization of potassium levels. (ecgwaves.com)
Patient1
From a therapeutic perspective, treating a WCT with adenosine is unlikely to cause the patient serious harm even if the underlying rhythm is VT. (emra.org)
