Patent ID: 6978177

Claim:
A method for providing pacing therapy to a heart, comprising: establishing discrimination criteria for distinguishing at least two different types of supraventricular tachycardia having regular rapid supraventricular heart rates; sensing activity of at least one atria of the heart to provide an atrial activity signal; comparing at least one characteristic of the atrial activity signal to the discrimination criteria to identify one of the at least two different types of supraventricular tachycardia having regular rapid supraventricular heart rates; and controlling pacing of the heart to provide atrial antitachycardia pacing in response to an identified first one of the at least two different types of supraventricular tachycardia and to provide ventricular pacing in response to an identified second one of the at least two different types of supraventricular tachycardia.
