Atrial flutter, the second most common pathologic supraventricular tachycardia, results from a reentrant circuit around the tricuspid valve in the right atrium (although atypical flutters do occur ...

Supraventricular tachycardia is a term used to describe any heart rhythm that is greater than 100 beats per minute originating from above the AV node (the atrium). The term “SVT” can be ...

When the heart rate is significantly elevated ― that is, greater than 150 bpm ― it is frequently difficult to differentiate atrial flutter from atrial fibrillation, atrial tachycardia or ...

Tachycardia refers to a fast resting heart rate, usually over 100 beats per minute (bpm) in adults. Some people experience no symptoms, but others may notice palpitations and lightheadedness ...

SVT causes abnormally fast heart rhythms in the upper chambers (atria), with or without heart disease. Atrial fibrillation (an irregular, rapid heartbeat) and atrial flutter (a fast, regular ...

The approval was based on data from 5 randomized, double-blind, placebo-controlled trials that included 317 patients with supraventricular tachycardia. Landiolol is a selective beta-1 adrenergic ...

There are three major groups of fetal tachyarrhythmias: atrial flutter/fibrillation, supraventricular tachycardia, and multifocal atrial extrasystoles. 1 Sustained tachyarrhythmias can result in a ...

Atrial tachycardia is a type of irregular heart rhythm that doctors call an arrhythmia. Other arrhythmias that originate in the atria include atrial flutter and atrial fibrillation.
