人工心脏起搏器原本是对缓慢性心律失常使之增加心率的一种方法。临床中,约一半以上用于缓慢性心律失常。但最近对快速心律大常也开始应用起搏器治疗,例如对药物治疗无效的室上性心动过速使用起搏器,而对特别危险的室速和室颤,则不使用起搏器,一部分医疗单位已使用了植入型除颤器。本文对人工起搏器预防恶性心律失常和体内植人式除颤器的使用现状及存在问题作一讨论。一、对室上速行人工起搏对室上速首先是药物治疗,对用药物难于控制的折返性心动过速等,可行心房高频刺激法和心房期前刺激法等终止心动过速。这是将电生理学技术应用于起搏器,在术前进行电生理学检查时,应反复行心动过速的诱发和终 Artificial pacemakers were originally a way to increase heart rate with bradyarrhythmias. About half of clinically used for slow arrhythmia. However, pacemakers have also recently begun to apply rapid tachyarrhythmias, such as pacemakers for supraventricular tachycardias that are ineffective for medical therapy, pacemakers for particularly dangerous ventricular tachycardia and ventricular fibrillation, and part of them Medical units have used implantable defibrillators. This article discusses the use of artificial pacemaker to prevent malignant arrhythmias and implantable defibrillators and the existing problems. First, the rapid pace of artificial walking on the room Superficial speed is the first drug treatment, the use of drugs difficult to control the reentrant tachycardia, viable atrial high-frequency stimulation and atrial pre-stimulation and other termination of tachycardia. This is the application of electrophysiological techniques in pacemakers, preoperative electrophysiological examination should be repeated tachycardia induction and termination
