A system and method for treating an arrhythmia of the heart, involves delivery of anti-tachy pacing (ATP) pulses to the heart, possibly followed by the delivery of a high-voltage shock. ATP delivery is controlled such that the time delivery of any high-voltage shock is not affected by the prior delivery...http://www.google.de/patents/US6892094?utm_source=gb-gplus-sharePatent US6892094 - Combined anti-tachycardia pacing (ATP) and high voltage therapy for treating ventricular arrhythmias
