ABSTRACT:
A cardiac implant device is provided in which the ventricular rate is monitored to differentiate between atrial fibrillation and ventricular tachycardia or other cardiac conditions. For this purpose, the ventricular rate stability is monitored by, for example, measuring the R-R intervals of successive ventricular beats. If the ventricular rate is found to be unstable, the ventricle is paced at a test rate to try to stabilize the ventricle. If the attempt is unsuccessful, atrial fibrillation is assumed and, if necessary, corresponding therapy is applied. If the attempt is unsuccessful, atrial fibrillation is eliminated as a cause of the ventricular rate instability and other types of classifying and treating the cardiac condition may be used.
