Supraventricular7

• However, paroxysmal tachycardias may occur (primarily supraventricular) and cause faints. (medscape.com)
• In the presence of a reentrant-induced arrhythmia, such as paroxysmal supraventricular tachycardia (PSVT) and ventricular tachycardia (VT), electrical cardioversion interrupts the self-perpetuating circuit and restores a sinus rhythm. (medscape.com)
• Adenosine slows conduction time through the A-V node, can interrupt the re-entry pathways through the A-V node, and can restore normal sinus rhythm in patients with paroxysmal supraventricular tachycardia (PSVT), including PSVT associated with Wolff-Parkinson-White Syndrome. (nih.gov)
• A cumulative 60% of patients with paroxysmal supraventricular tachycardia had converted to normal sinus rhythm within one minute after an intravenous bolus dose of 6 mg adenosine injection (some converted on 3 mg and failures were given 6 mg), and a cumulative 92% converted after a bolus dose of 12 mg. (nih.gov)
• Conversion to sinus rhythm of paroxysmal supraventricular tachycardia (PSVT), including that associated with accessory bypass tracts (Wolff-Parkinson-White Syndrome). (nih.gov)
• Supraventricular tachycardia - ventricular complexes (QRS) are unchanged, while the teeth P and T merge. (arrhythmia.center)
• Atrioventricular Nodal Reentrant Tachycardia is a type of supraventricular tachycardia (ie it originates above the level of the Bundle of His) and is the commonest cause of palpitations in patients with hearts exhibiting no structurally abnormality. (crashingpatient.com)

Bradycardia2

• Electrocardiograph showed cardiac arrhythmia with sinus bradycardia, ventricular premature beats, and paroxysmal ventricular tachycardia. (cdc.gov)
• Sick sinus syndrome - a disturbance of SA nodal function that results in a markedly variable rhythm (cycles of bradycardia and tachycardia). (cvphysiology.com)

PSVT1

• Adenosine is not effective in converting rhythms other than PSVT, such as atrial flutter, atrial fibrillation, or ventricular tachycardia, to normal sinus rhythm. (nih.gov)

Hypertension2

• It causes persistent or paroxysmal hypertension. (msdmanuals.com)
• The most common presenting feature is hypertension, which can be sustained or paroxysmal. (medicalexamprep.co.uk)

Arrhythmias3

• However, those that result in hypotension, increase myocardial oxygen requirements, and/or predispose the patient to develop additional malignant ventricular arrhythmias should be aggressively monitored and treated. (medscape.com)
• Once this has been achieved, beta-blockade can be commenced, which helps top control tachycardia and certain arrhythmias. (medicalexamprep.co.uk)
• A separate place is occupied by tachycardias in the group of arrhythmias, where they are defined as sinus, paroxysmal, ventricular tachycardia. (arrhythmia.center)

Postural1

• Paroxysmal attacks may be provoked by palpation of the tumor, postural changes, abdominal compression or massage, induction of anesthesia, emotional trauma, unopposed beta-blockade (which paradoxically increases blood pressure by blocking beta-mediated vasodilation), or micturition (if the tumor is in the bladder). (msdmanuals.com)

Orthostatic2

• In the absence of structural heart disease (including a normal ECG), syncope is most often of neurally mediated reflex origin or orthostatic hypotension. (medscape.com)
• [ 1 ] However, a certain number of these patients are more likely to have experienced hypotension on an orthostatic basis, especially if they are being treated with diuretic or vasodilator drugs. (medscape.com)

Ventricular rate1

• however, it can have serious consequences if the ventricular rate is sufficiently rapid to precipitate hypotension, myocardial ischemia, or tachycardia-induced myocardial dysfunction. (health.am)

Precipitate hypotension1

• Procainamide may precipitate hypotension in left ventricular failure or impaired function. (truman.edu)

Normal sinus3

• The remaining patients had normal sinus rhythm or sinus tachycardia. (medscape.com)
• Fifteen years later, Lown applied synchronized DC shocks to the heart to convert atrial fibrillation (AF, afib) and ventricular tachycardia (VT, vtach) to normal sinus rhythm. (medscape.com)
• Adenosine injection does not convert atrial flutter, atrial fibrillation, or ventricular tachycardia to normal sinus rhythm. (nih.gov)

Procainamide1

• The most frequent adverse event in the procainamide patients was transient hypotension. (medscape.com)

Myocardial Infarction1

• But on the electrocardiogram it was possible to fix ventricular tachycardia, which developed on the background of a myocardial infarction, only in 1921. (arrhythmia.center)

Norepinephrine2

• At admission to The First Affiliated Hospital of Zhejiang University School of Medicine, he had sepsis, hypotension, and leukocytosis and immediately received norepinephrine intravenous pumping, endotracheal intubation, sedation, mechanical ventilation, and continuous renal replacement therapy. (cdc.gov)
• The Hamburg medical center's institutional routine was to maintain MAP (mean arterial pressure) above 65 mmHg, and intraoperative hypotension was treated with intravenous norepinephrine, which was given at the discretion of each attending anesthesiologist. (theanesthesiaconsultant.com)

Arterial4

• A study in the September 2023 issue of Anesthesiology showed that continuous finger-cuff arterial pressure monitoring helped anesthesia professionals a) reduce hypotension during the 15 minutes following induction of general anesthesia, and b) reduce hypotension during the duration of noncardiac surgery, compared to traditional intermittent oscillometric arterial pressure monitoring. (theanesthesiaconsultant.com)
• Results showed that continuous finger-cuff arterial pressure monitoring helped anesthesia providers a) reduce hypotension within the first 15 minutes after starting induction of anesthesia, and b) reduce hypotension during the entire noncardiac surgery. (theanesthesiaconsultant.com)
• A second study of 316 patients undergoing noncardiac surgery showed that continuous finger-cuff arterial pressure monitoring nearly halved the amount of intraoperative hypotension, defined as the time-weighted average MAP less than 65 mmHg. (theanesthesiaconsultant.com)
• Severe arterial hypotension (systolic blood pressure (BP) less than 90 mm Hg and diastolic blood pressure less than 50 mm Hg). (bestpharmbuy.com)

Acute5

• Arrhythmogenesis early in the course of an acute coronary syndrome (ACS), manifested often as polymorphic ventricular tachycardia (VT) or ventricular fibrillation (VF) is observed in a minority of patients with acute ischemia, and it is often associated with genetic predisposition. (medscape.com)
• Flecainide is an IC antiarrhythmic drug approved in 1984 from Food and Drug Administration for the suppression of sustained ventricular tachycardia and later for acute cardioversion of atrial fibrillation (AF) and for sinus rhythm maintenance. (encyclopedia.pub)
• Flecainide was first synthesized in 1972 and approved in 1984 from the Food and Drug Administration (FDA) for the suppression of sustained ventricular tachycardia [ 1 ] and later for acute cardioversion of AF and for sinus rhythm maintenance. (encyclopedia.pub)
• gammaCore (nVNS) is FDA cleared in the United States for adjunctive use for the preventive treatment of cluster headache in adult patients, the acute treatment of pain associated with episodic cluster headache in adult patients, and the acute and preventive treatment of migraine in adolescent (ages 12 and older) and adult patients, and paroxysmal hemicrania and hemicrania continua in adult patients. (electrocore.com)

Chest Pain1

• 150 beats per minute [bpm]) who is unstable (eg, chest pain, pulmonary edema, lightheadedness, hypotension) should be immediately treated with synchronized electrical cardioversion. (medscape.com)

Arrhythmia2

• Paroxysmal - an arrhythmia that suddenly begins and ends. (cvphysiology.com)
• Electrical cardioversion is much less effective in treating arrhythmia caused by increased automaticity (eg, digitalis-induced tachycardia, catecholamine-induced arrhythmia) because the mechanism of the arrhythmia remains after the arrhythmia is terminated and therefore is likely to recur. (medscape.com)

Nodal2

• Sinus tachycardia - high sinus rate of 100-180 beats/min as occurs during exercise or other conditions that lead to increased SA nodal firing rate. (cvphysiology.com)
• Efrimov and other American researchers studied nodal tachycardia and were able to demonstrate its association with the heterogeneous distribution of connective tissue in the AV node. (arrhythmia.center)

Intravenous1

• Synchronized electrical cardioversion may also be used to treat stable ventricular tachycardia (VT, vtach) that does not respond to a trial of intravenous medications. (medscape.com)

Findings2

• Testing primarily consists of tilt-table testing and carotid massage, although electrophysiologic (EP) testing may be essential in those cases in which medical history, ECG, or cardiac monitoring findings suggest paroxysmal tachycardias. (medscape.com)
• 2. Clinical findings may include the triad of hypotension, JVD , and clear lungs. (umaryland.edu)

Abnormal2

• usually because of abnormal focus within the atria and paroxysmal in nature, therefore the appearance of P wave is altered in different ECG leads. (cvphysiology.com)
• Untreated abnormal tachycardia may pose a risk to human health. (arrhythmia.center)

Beats per mi2

• Tachycardia should be understood as the accelerated work of the heart, which determines more than the upper threshold of the age norm (in adults it is more than 100 beats per minute). (arrhythmia.center)
• If pathological impulses follow from the atrium, then the heart rate may be 200-350 beats / min, with a ventricular tachycardia, then 150-200 beats per minute. (arrhythmia.center)

Autonomic1

• Most often, the tachycardia develops when the autonomic nervous system works disorder, and an increased frequency of heart rate is observed in endocrine diseases and various hemodynamic disorders. (arrhythmia.center)

Chronic1

• In most such cases, atrial fibrillation is an unrecognized chronic or paroxysmal condition and should be managed accordingly (see below). (health.am)

Severe1

• Lactic acidosis secondary to severe anemia in a patient with paroxysmal nocturnal hemoglobinuria. (derangedphysiology.com)

Complications1

• Previous studies have validated that both the severity and the duration of intraoperative hypotension are associated with postoperative complications and mortality . (theanesthesiaconsultant.com)

Amplitude1
