Abstract
A method of determining a defibrillation threshold for an implantable cardiac defibrillator, based upon determining the 50% probability of reaching the upper limit of vulnerability. The 50% probability of reaching the upper limit of vulnerability at the mid-upslope of the T-wave is found to closely approximate the 50% probability of successful defibrillation used to set the shock energy level of the defibrillator. A delayed up-down algorithm is used to determine the shock strength associated with 50% probability of reaching the upper limit of vulnerability.
