引言植入式自动复律器/除颤器是一种拯救生命的装置。通过释放高能的电冲击,它能够对威胁人类生命的恶性室性过速性心律失常如室颤(VF)等作出反应。准确地区分过速性心律失常(室颤、室性心动过速和室上性心动过速)是非常重要的,无论是假阳性还是假阴性都必须减到最小。心内信号可以在时域或频域中进行信号分析处理。现有的方法也许不适合作实时的 Introduction Implantable Cardioverter / Defibrillator is a life-saving device. By releasing high-energy electrical shocks, it responds to malignant ventricular tachyarrhythmia such as ventricular fibrillation (VF), which is a threat to human life. Accurately distinguish tachyarrhythmia (ventricular fibrillation, ventricular tachycardia and supraventricular tachycardia) is very important, whether it is false or false negative must be minimized. Intracardiac signals can be analyzed in the time or frequency domain. Existing methods may not be suitable for real-time
