Key result
External cardiac defibrillation advances with novel waveforms and individualized patient-specific protocols.
Why the study?
Resuscitation success rates remain unsatisfactory for patients with malignant arrhythmias such as ventricular fibrillation and ventricular tachycardia undergoing external defibrillation.
This review provides a comprehensive overview of emerging external defibrillation technologies, emphasizing the transition toward personalized resuscitation strategies.
Advances in defibrillation support testing of novel waveforms and personalization; leaves open whether these improve outcomes in clinical practice.
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.
