Patent ID: 7386342

Claim:
A system comprising: an implantable subcutaneous device comprising: at least two subcutaneous electrodes adapted for placement near a heart but neither in nor on a heart; an arrhythmia detector that detects a tachyarrhythmia of the heart; a first pulse generator operative to deliver pacing pulses to the subcutaneous electrodes, the pacing pulses having a waveform devoid of any exponential voltage decay; a telemetry device; a processor programmed to output a command through the telemetry device to deliver one or more of anti-tachycardia pacing therapy, cardioversion therapy or defibrillation therapy; and a fully implanted stimulation device comprising: at least one intracardiac electrode adapted for placement within or on a heart; a second pulse generator that delivers one or more of anti-tachycardia pacing therapy, cardioversion therapy or defibrillation therapy to the heart using the at least one intracardiac electrode in response to the command from the telemetry device.
