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.
