Kammerflimmern/-flattern: Prädiktoren für den Defibrillationserfolg?

Although electrical defibrillation remains the method of choice for treatment of ventricular fibrillation, repeated defibrillation attempts can lead to myocardial damage and consequently deterioration of the patient's outlook for survival. In situations involving prehospital resuscitation,measurements of the coronary perfusion pressure and end-expiratory CO₂ concentration are not suited for optimizing the effectiveness of defibrillation.Hence new noninvasive parameters are being sought to detect the appropriate point in time for defibrillation. Signal analysis of surface EKG enables determination of amplitude and frequency parameters whose value as predictors of successful defibrillation is presented in this study.Defibrillators of the future could decide the optimal point in time for defibrillation themselves.
