Abstract
An implantable medical device and method for providing therapy to a patient's inadequately functioning heart are disclosed. The device and method utilize a defibrillation electrode lead system to deliver defibrillation therapy to the patient's heart, and a defibrillator to provide the defibrillation therapy that is delivered by the defibrillation electrode lead system. The defibrillator includes a charge storing circuit for storing an electrical charge therein. Controls are employed for charging the charge storing circuit to an appropriately high energy level for use in defibrillation therapy, in response to a detected tachycardia condition, and for charging the charge storing circuit to an appropriately low energy level for selectively inducing an arrhythmia in the patient's heart. Switching circuitry is utilized to couple the charge storing circuit to the defibrillation electrode lead system; and, controls are provided for selectively actuating the switching circuitry to generate a plurality of micro-shocks from the low energy electrical charge in the charge storing circuit and to deliver the micro-shocks to the defibrillation electrode lead system.
