Previous Case: McGill Case 156 | Next Case: McGill Case 158

This is an example of time dependent capture. The native QRS complexes are small (and grow larger due to the auto gain control on this recorder), and the rhythm is probably a nodal escape with sinus arrest. The pacer is a dual chamber where the atrial lead captures but the ventricular lead captures only if it falls close to a T wave of one of the native escape beats.
