Abstract

An algorithm is described for discrimination of supraventricular tachycardia (SVT) and ventricular tachycardia (VT) in implantable arrhythmia termination devices. The sequential hypothesis testing method the authors apply allows an elegant tradeoff between accuracy and detection time. The false positive (FP) and false negative (FN) rates are predefined within the algorithm for each decision that the program makes. Detection time can be decreased if absolute accuracy is not essential, and the accuracy of the algorithm can be increased at the expense of a quick decision. 30 data segments were analyzed. 23 of the segments were correctly classified within 3 s and all 30 were correctly diagnosed in 8 s.
