Wandering atrial pacemaker is similar to multifocal atrial tachycardia except the heart rate is normal ― that is, less than 100 beats per minute. Wandering atrial pacemaker occurs when multiple ...

Multifocal atrial tachycardia is a tachycardic version of wandering atrial pacemaker in which the atrial rate is greater than 100 beats per minute. Multifocal atrial tachycardia occurs when ...

In none of the patients intermittent 2:1 retrograde conduction was noted during ventricular pacing. When 1:1 retrograde atrial activation was present in the simultaneously recorded ECG and atrial ...

Patients requiring a pacemaker often have atrial fibrillation (AF), which increases the risk of thromboembolism and, consequently, the risk of morbidity and mortality. To maintain sinus rhythms ...

Since detailed electrocardiogram (ECG ... to be paced at a pacemaker ventricular rate of 40 bpm. Patients were considered nonpacemaker dependent if they had sinus rhythm or atrial fibrillation ...
