ABSTRACT:
An apparatus and method for controlling pulse energy in an arrythmia control device wherein bradycardia pacing pulses are normally delivered at a first energy, and after antitachycardia therapy, bradycardia pulses are delivered at a second energy, the second energy being greater than the first energy. The antitachycardia therapy may be at least one of antitachycardia pacing, cardioversion and defibrillation; and is delivered at a third energy level greater than said second energy level. The second energy level is maintained for a predetermined period of time and then returned to the normal bradycardia pacing energy.
