Abstract
An implantable defibrillator generates defibrillation shocks for providing antitachycardia therapy. The shocks have an intensity, i.e. amplitude and/or duration, which is dynamically changed in accordance with whether defibrillation shocks having a particular intensity are successful or not. In this manner, changes either in the cardiac condition or the interface between the defibrillation electrodes and the cardiac tissues, or other causes which may have an effect on the effectiveness of the defibrillation shocks.
