ability of a pacemaker to increase the pacing rate in response to physical activity or metabolic demand
ECG waveform that results when an intrinsic depolarization and a pacing stimulus occur simultaneously and both contribute to depolarization of that cardiac chamber
discharges only when the patient's heart rate drops below the pacemaker's preset rate
in dual-chamber pacing, the interval between a sensed or ventricular-paced event and the next atrial-paced event
rate at which the pulse generator of a pacemaker paces when no intrinsic activity is detected; expressed in pulses per minute
in dual-chamber pacing, the length of time between an atrial sensed or atrial paced event and the delivery of a ventricular pacing stimulus; analogous to the P-R interval of intrinsic waveforms
a pacing system with a lead attached to the right atrium designed to correct abnormalities in the SA node
pacemaker response in which the output pulse is suppressed when an intrinsic event is sensed
in pacing, the ECG waveform that results when an intrinsic depolarization and a pacing stimulus occur simultaneously
ability of a pacing stimulus to successfully depolarize the cardiac chamber that is being paced
artificial pulse generator that delivers an electrical current to the heart to stimulate depolarization
pacing system analyzer
external testing and measuring device capable of pacing the heart during pacemaker implantation
period, expressed in milliseconds, between two consecutive paced events in the same cardiac chamber without an intervening sensed event
pacing lead with a single electrical pole at the distal tip of the pacing lead (negative pole) through which the stimulating pulse is delivered
