全自动型起搏器简称DDD型起搏器,它是一种模拟正常心脏的生理性双腔按需起搏器。因其具有房室顺序起搏,能取得良好的血液动力学效应,自70年代未应用以来,受到临床的好评和推广。我院近年安置二台DDD型起搏器取得良好效果。因DDD的安置较VVI型起搏器复杂,现将安置过程中的几点体会归纳如下。一、临床资料:2例病人男女各1人,年龄分别为74岁、54岁;疾病诊断及心电图改变:1例冠心病Ⅲ度房室传导阻滞,心室率 32～36次/分;另1例为病态窦房结综合征,心率26～54次/分。二例病人均无房颤、室上性心动过速发作史,但均有头 Automatic pacemakers referred to as DDD pacemaker, it is a simulated normal heart physiology dual-chamber on-demand pacemaker. Because of its atrioventricular pacing, can achieve good hemodynamic effects, since the 1970s have not been applied, clinically praised and promoted. In recent years, our hospital placement of two DDD-type pacemaker achieved good results. Due to the DDD placement more complex than the VVI pacemaker, resettlement process will now be summarized in the following points. First, the clinical data: 2 patients with 1 male and 1 female, respectively, aged 74 years, 54 years old; diagnosis of disease and ECG changes: 1 case of coronary heart disease Ⅲ degree atrioventricular block, ventricular rate 32 to 36 beats / min; 1 case of sick sinus syndrome, heart rate 26 ~ 54 beats / min. Two patients had no atrial fibrillation, supraventricular tachycardia episodes, but both heads
