Pacemaker Failure to Capture | Reference Guide
EKG Features
Rate: Slow or normalRhythm: Irregular
P Wave:
PR Interval:
QRS:
Indicated by the presence of a pacing spike, but a waveform will not immediately follow it.
Pacemaker failure to capture occurs when the pacemaker does not depolarize the myocardium. On a rhythm strip, this can be observed as pacemaker impulses (spikes) which are not followed by p waves and QRS complex.
