心脏人工起搏技术现已成为临床心血管疾病抢救措施之一,它使一大批有严重缓慢型心律失常的患者转危为安、起死回生。随着心脏起搏技术的发展,起搏器的性能也日臻完善,房室顺序型(DDD型)人工起搏器的诞生就是现代医学临床上的一种新的开拓。我科于1991年6月对2例患者安装DDD人工起搏器,并取得了成功,这在我区尚属首创。 DDD人工心脏起搏器在临床上的应用在我国只是近1～2年的事。与心室起搏器(VVI)相比,它是房室顺序同步起搏。双腔感知,当心房起搏后延迟0.12～0.20s后心室起搏,符合生理性心脏起搏顺序,可 Cardiac artificial pacing technology has become one of the clinical cardiovascular disease rescue measures, it makes a large number of patients with severe arrhythmia turn critically ill, back to life. With the development of cardiac pacing technology, the performance of pacemaker is also getting better. The birth of an atrium-type (DDD) artificial pacemaker is a new clinical practice in modern medicine. Our department in June 1991 to 2 patients with DDD artificial pacemaker, and achieved success, which is still the first in our region. DDD artificial pacemaker in clinical application in China is only a matter of 1 to 2 years. Compared with the ventricular pacemaker (VVI), it is atrioventricular synchronized pacing. Dual-chamber perception, when the atrial pacing delayed 0.12 ~ 0.20s after ventricular pacing, in line with physiological cardiac pacing sequence may
