This ectopic focus becomes the predominant pacemaker of the heart. When the atrial rate is greater than 100 beats per minute, the rhythm is atrial tachycardia. If less than 100 beats per minute ...

Wandering atrial pacemaker occurs when multiple areas (ectopic foci) within the atrium generate consecutive action potentials that are all conducted to the ventricles. Thus, each QRS complex will ...

including both atrial fibrillation and flutter in pacemaker recipients with and without arrhythmia history are not well understood. The Atrial High Rate Episodes (A-HIRATE) in Pacemaker Patients ...
