Abstract
In an apparatus for determining the AV transmission time or AV delay in the heart, the apparatus having a signal-sensor arrangement that is disposed in the heart and detects a natural cardiac action, further having at least one signal output and a processing unit that has at least one signal input that is connected to the signal output of the signal-sensor arrangement for calculating the natural AV transmission time based on the detected cardiac action, the signal-receiver arrangement includes a pressure-sensor arrangement that is disposed in the vicinity of the tricuspid valve in the right atrium and/or in the right ventricle for detecting intracardial pressure changes associated with the opening of the tricuspid valve.
