Abstract
In a method and apparatus for determining whether electrical signals in a heart are caused by atrial depolarizations or ventricular depolarizations, heart signals are sensed in the upper part of the ventricular heart tissue, preferably the upper part of the ventricular septum. The detection of heart signals from both the atrium and ventricle and the identification of depolarization is facilitated if the course of the signals is monitored, with monophasic heart signals being caused by an atrial depolarization and biphasic signals being caused by a ventricular depolarization.
