Abstract

An implantable medical device for stimulating a human or animal heart. In operation, the device performs the following steps: a) sensing an atrial electric signal a the first detection unit; b) sensing an electric signal at the His bundle with a second detection unit upon termination of a first time period starting upon sensing the atrial electric signal with the first detection unit and/or starting upon applying a stimulation pulse, wherein the first time period lies in a range of from 10 ms to 100 ms; c) classifying the electric signal sensed with the second detection unit as His bundle activity signal or as ventricular activity signal.
