Asynchronous pacing: (a = not; syn = together; chrono = time) are those that are not together in
time with the heart because they do not know what the heart is doing.
Pacemakers such as AOO and VOO are asynchronous as they stimulate the
heart at a fixed, preset rate independent of the electrical and/or
mechanical activity of the heart.
Burst Pacing: Is a technique of rapid pacing which may be used to terminate a
tachycardia by delivering a series of pacing pulses in which the delivery rate
remains constant within each pacing attempt. This technique is used in both
the atria and the ventricles to attempt to terminate organized arrhythmias.
Capture: Is initiation of depolarization of the atria and/or ventricles by an electrical
stimulus delivered by an artificial pacemaker. Capture can be visualized on
the monitor by a spike before every p wave (for atrial pacing) and a spike
before every QRS (for ventricular pacing)
Demand Pacing: A pacing stimulus is delivered to the myocardium if the intrinsic rate falls
below the set rate on the pacemaker.
Dual-Chamber Pacemaker: A pacemaker with two leads (one in the atrium and one in the ventricle) to
allow pacing and/or sensing in both chambers of the heart to artificially
restore the natural contraction sequence of the heart.
Epicardial Pacing: Is a type of temporary pacing where pacing wires are fixed directly to the
myocardium (ventricular and often atrial) and are exposed through the skin
on the chest wall, usually following cardiac surgery.
