Abstract
An implantable cardioversion/defibrillation device includes a cardioversion signal generator and a defibrillator signal generator. Heart beat rates are classified into a first, an intermediate and a second range. A ventricle state determinator is also provided to determine the current status of the ventricle. At the low and high rates cardioversion and fibrillation signals are generated and applied to the heart, respectively. At the intermediate rate, if the ventricle is stable, cardioversion signals are generated and applied. If the ventricle is unstable, then defibrillation signals are applied. Ventricle stability is determined from the variability of the ventricular rate.
