Method for detecting and controlling endless loop tachycardias of a heart being controlled by a cardiac pulse generator

摘要

A method for detecting and controllig endless loop tachycardia (ELT) of a heart being controlled by a cardiac pulse generator.P PA measurement is made of the VP time interval over eight cycles and of its maximum deviation which is compared with two threshold values. PPA modulation is applied to the atrio-ventricular delay and the following VP time interval is measured during the ninth cycle. The variation of the VP time interval is compared with the threshold values for determining whether one is dealing with an ELT or with a sinus rhythm.
