Antitachycardia pacing

One very effective strategy is antitachycardia pacing (ATP), a capability which is incorporated in most ICDs. ATP painlessly terminates sustained... [Pg.45]

Fig. 12.2 An example of atrial fibrillation (AF) organizing into atrial flutter. A. The upper strip in the top panel demonstrates the atrial electrogram (EGM) and the lower strip demonstrates the annotated markers indicating how the pacemaker classifies each atrial and ventricular event as well as the cycle length (in ms) between each interval. The atrial electrogram shows the rapid irregular atrial rhythm which subsequently transitions into an organized atrial tachycardia. B. Atrial antitachycardia pacing (ATP) therapy - a burst train followed by two premature extrastimuli is delivered restoring atrial paced rhythm. The marker channel notations indicate how the device classifies each beat. Inter-beat intervals are also shown (in ms). AP - atrial paced event VP - ventricular paced event AR - atrial event sensed in atrial refractory period FS - AF sensed event TD - tachycardia detected TS - tachycardia sensed event.

ICDs can deliver a range of therapies depending on the arrhythmia detected and how the device is programmed. Some ICDs can also detect and treat atrial arrhythmias or provide biventricular pacing. Therapies include antitachycardia pacing, cardioversion, defibrillation, and bradycardia pacing. ... [Pg.122]
