AMPS-1 OPERATING MANUAL
8 Pacemaker
8.1 Overview
An artificial pacemaker, or "pacer", is a medical device designed to regulate the beating
of the heart. External pacemakers can be used for initial stabilization of a patient, but
implantation of a permanent pacemaker is sometimes required.
Pacing can be instituted for many reasons: in the case of slow ventricular rate
(bradycardia, heart block) or rapid ventricular rate, atrial fibrillation or atrial flutter, or if
dangerous arrhythmias are noted when the ECG is monitored.
AMPS-1 simulates the presence of a pacer pulse with the ECG signal to allow the
evaluation of how a patient monitor deals with the pacer pulse.
