A microcomputer algorithm for tachycardia identification, suitable for use in un implanted antitachycardia pacemaker, is described. The system employs an atrial and ventricular electrogram, detects a sustained fast rate in either chamber, and awakens the main program to perform detailed analysis of the tachycardia and its immediately preceding beats. The algorithm distinguishes atrial, ventricular, and AV nodal and re‐entrant tachycardia from high rates due to sinus tachycardia. For testing of the program, we used a data base of twenty‐two tape‐recorded and documented arrhythmias provoked during electrophysiologic studies in which atrial and ventricular bipolar electrodes were in place; twenty‐one of twenty‐two wave successfully detected. These included atrial fibrillation, atrial flutter, atrial tachycardia, AV nodal re‐entrant tachycardia, AV re‐entrant tachycardia using an accessory pathway, and ventricular tachycardia with and without ventriculo‐atrial conduction.
