Claim One:
1. A method for distinguishing between different types of rapid regular supraventricular tachycardia, comprising: establishing an atrial discrimination algorithm including discrimination criteria for distinguishing between different types of rapid regular supraventricular tachycardia; sensing activity of at least one of the atria of the heart to provide an atrial activity signal; applying the atrial discrimination algorithm to the atrial activity signal to compare at least one characteristic of said atrial activity signal to the discrimination criteria to identify the type of rapid regular supraventricular tachycardia occurring; and providing an indication corresponding to the type of rapid regular supraventricular tachycardia identified, wherein establishing an atrial discrimination algorithm includes establishing discrimination criteria for distinguishing between fast atrial flutter at a first high rate and an other atrial flutter at a second lower rate.
