P-Wave Sensing

Resetting

Pacemaker Output is below threshold. A period of asystole occurs before the

idioventricular rhythm begins.

Pacemaker Output is well above threshold. Every stimulus is followed by a QRS,

verifying capture.

Pacemaker Output is near threshold of stimulation. Only every other pulse is followed by a QRS.
