Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...

Narrow QRS complexes occur regularly. This tracing suggests either atrial flutter or ventricular tachycardia. It is not atrial flutter, however. If it were, the QRS complexes occurring regularly would ...

This patient had classic atrial flutter with a cycle length of 240 msec prior to ablation. The P waves were deeply negative in ECG leads II, III, and aVF, and were initially upright in V1. Note that ...

Many authorities recommend digoxin for one year for atrial flutter (AT.FL) in infants with normal structural hearts. To re-examine this recommendation the electrocardiogram, response to programmed ...

An abnormal heart rhythm, also known as an arrhythmia, occurs when the heart beats too fast, too slow, or irregularly, which can be caused by various factors affecting the heart’s complex system.

Multifocal atrial tachycardia Old inferior myocardial infarction Premature supraventricular beat with aberrancy (left bundle branch block pattern). Multifocal atrial tachycardia (MAT) occurs when ...

Two studies to be presented this week address the often-overlooked costs associated with atrial fibrillation (AFib), the most common form of cardiac arrhythmia. Each study evaluates these costs and ...
