![]() | Media file 1: Atrial undersensing. Rhythm strip showing an atrial pacing artifact after the intrinsic P wave. |
![]() | Media file 2: Ventricular undersensing. Rhythm strip showing ventricular pacing artifacts despite normal underlying ventricular activity. |
![]() | Media file 3: Atrial lead dislodgement. Chest radiograph film detail showing dislodged atrial lead with tip in the right ventricular cavity. |
![]() | Media file 4: Ventricular noncapture. Rhythm strip showing atrial (P wave) sensing followed by ventricular spike, which failed to capture the ventricle. |
![]() | Media file 5: Loss of atrial capture. Rhythm strip showing intermittent loss of atrial capture. |
![]() | Media file 6: Pacemaker-mediated tachycardia. Rhythm strip showing ventricular pacing at 110 beats per minute (programmed maximal track rate). |
![]() | Media file 7: Termination of pacemaker-mediated tachycardia. Automatic postventricular atrial refractory period (PVARP) extension terminated the PMT. |
