What Is Atrial Overdrive Pacing

What Is Atrial Overdrive Pacing. A term defined in the context of implantable pacemakers for the delivery—e.g., atrial burst pacing—of rapid, multiple electrical pulses, to pace the heart faster than its intrinsic rate. Atrial overdrive pacing inducing qrs complexes of varying duration in a patient with recurrent syncope.

Termination of the tachycardia with pacing often immediate. In the middle trace, which begins 12 seconds after the top trace, atrial capture is shown clearly. Pacing algorithms to prevent atrial fibrillation (af) have been tested in studies of modest size and duration with inconclusive results.

So whenever possible atp should be administered through an atrial lead. High rate pacing during the vulnerable period following restoration of sinus rhythm may therefore prevent iraf. Temporary cardiac pacing (tcp) is a type of exogenous cardiac pacing in which an external energy source delivers electrical impulses to stimulate the heart to contract faster than its native rate. An alternate approach is to initiate atrial pacing at a rate 20 beats/min faster than the intrinsic atrial rate;
