人工心脏起搏是近十余年来在心脏疾病治疗中的一项重要进展,它对抢救与治疗某些危及生命的严重心律失常具有肯定的价值。本文简述人工心脏起搏的有关问题、起搏指征、起搏的并发症及其注意事项。人工心脏起搏的有关问题心动周期中的易损期在心动周期中,易损期在T波顶峰的前面,在所有哺乳类动物,实验发现这个间期为20～40毫秒。易损期与心脏起搏很有关系,若在这个间期中给予一定量的刺激,可以促发心室颤动。在正常动物,需在易损期上给予
Artificial heart pacing is an important progress in the treatment of heart disease in the past ten years. It has certain value in the rescue and treatment of some serious life-threatening arrhythmias. This article describes the issues related to artificial cardiac pacing, pacing indications, complications of pacing and their precautions. Issues related to artificial cardiac pacing The vulnerable period in the cardiac cycle During the cardiac cycle, the perishable period precedes the T wave peak, and in all mammalian animals, the interval was found to be 20 to 40 milliseconds. Vulnerable period and cardiac pacing are closely related, if given in this interval a certain amount of stimulation, can trigger ventricular fibrillation. In normal animals, to be given in the vulnerable period
