Abstract

Dual-chamber pacemaker is a fully automatic pacemaker with the function of simulating human physiological pacing. It regulates pacing by programming different refractory periods and various special functions, which are closely related to arrhythmia. After in-depth understanding of these special functions, regular ECG follow-up analysis is required to provide individualized optimal program control and so is appropriate administrations of special functions of pacemaker so as to better provide optimal clinical guidance for patients with arrhythmia.
