AN IMPLANTABLE MEDICAL DEVICE AND A METHOD COMPRISING MEANS FOR DETECTING AND CLASSIFYING VENTRICULAR TACHYARRHYTMIAS

摘要

The invention relates to ventricular tachyarrhythmia detection and classification. Upon detection of a ventricular tachyarrhythmia based on an electrocardiogram signal, cardiogenic impedance data representative of ventricular volume dynamics are collected and used for classifying the detected tachyarrhythmia as stable or unstable. In the latter case but typically not in the former case, defibrillation shocks or other forms of therapy are applied to combat the unstable ventricular tachyarrhythmia.
