As an important medical electronic equipment for the cardioversion of malignant arrhythmia such as ventricular fibrillation and ventricular tachycardia, cardiac external defibrillators have been widely used in the clinics. However, the resuscitation success rate for these patients is still unsatisfied. In this paper, the recent advances of cardiac external defibrillation technologies is reviewed. The potential mechanism of defibrillation, the development of novel defibrillation waveform, the factors that may affect defibrillation outcome, the interaction between defibrillation waveform and ventricular fibrillation waveform, and the individualized patient-specific external defibrillation protocol are analyzed and summarized. We hope that this review can provide helpful reference for the optimization of external defibrillator design and the individualization of clinical application.
作为一种复律心室颤动和室性心动过速等恶性心律失常的重要医疗电子设备，心脏体外除颤仪已经在临床上得到了广泛的应用。然而，目前临床对这类患者的抢救成功率依然不尽人意。本文就心脏体外电击除颤技术在近几年的研究进展进行了综述，并从心脏电击除颤的机制、新型体外除颤波形的设计、影响除颤结果的因素、除颤波形与室颤波形的相互作用和个性化体外除颤的方案等方面进行了分析与总结，为进一步优化心脏体外除颤仪的设计和临床应用提供参考。.
