The correct diagnosis is atrial flutter with variable block (Figure 2). The rhythm is regular at a rate of 150 beats/min; however, there are two long RR intervals (↔). The QRS complex is narrow (0.08 ...

The correct diagnosis is atrial tachycardia with variable block (Figure 2). Figure 2. Courtesy of Dr Podrid. The rhythm is basically regular at a rate of 50 beats/min, although the first and second ...

Atrial tachycardia is a form of supraventricular tachycardia that occurs when one focus in the atria begins to fire rapidly, overwhelming the sinoatrial node. This results in rapid conduction of ...

MANY common arrhythmias observed in both atria and ventricles are similar although the atrial types have a few important distinguishing features. Thus, so far as therapy is concerned, the atrial ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...

Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial rate in ...

Atrial tachycardia is an abnormal heart rhythm where the top chambers in your heart beat quicker than usual. During an atrial tachycardia episode, your heart rate may exceed 100 beats per minute (bpm) ...
