Ventricular tachyarrhythmia prediction and/or prevention

摘要

Embodiments of the present invention provide apparatuses and methods to predict and/or prevent episodes of ventricular tachyarrhythmia (for example, ventricular tachycardia and/or ventricular fibrillation). A method is provided for predicting an episode of ventricular tachyarrhythmia by detection and analysis of multiple patterns of vagal fatigue during a period of time.
