心脏起搏器的临床应用价值,已为广大医学界所接受。近年来,随着电子工程学的发展,临床起搏器方面,进展迅速。一、生理性起搏迄今为止,临床上使用最多的是心室按需型起搏器(VVI)。但单纯心室起搏时,失去了心房对心室排血的辅助作用,心排血量可下降20～30％,血压可能
The clinical value of pacemakers has been accepted by the general medical community. In recent years, with the development of electronic engineering, clinical pacemaker, the rapid progress. First, the physiological pacemaker So far, the most clinically used ventricular on-demand pacemaker (VVI). But simple ventricular pacing, the loss of atrial ventricular drainage of auxiliary role, cardiac output can be reduced by 20 to 30%, blood pressure may
