A wave generated from the depolarization of the atria; the P wave is upright when originating from the SA node. The P wave represents the Read More

Temporary transvenous pacing or an implanted cardiac pacemaker with a lead in an atria (typically right atria) that initiates a depolarizing wave (pacer spike followed Read More

A cardiac rhythm that is generated by current provided by an artificial pacemaker; vertical pacemaker spikes precede the waves. An electronic pacemaker, or just pacemaker, Read More

An electronic pulse generator that stimulates depolarization of the atria and/or the ventricles. 1. Six Second ECG Guidebook (2012), T Barill, p. 201 Read More

The main battery unit as well as the electronics for the pacemaker; often resides under the skin inferior to the clavicle. 1. Six Second ECG Read More

The telling sign that the rhythm is a paced rhythm; since the pacemaker spike is vertical, virtually no time was spent – this suggests strongly Read More

Small muscles that attach to the inner wall of the ventricles and to the chordae tendaneae (which in turn are connected to the heart’s valves). Read More
