Abstract
The invention relates to an implantable ventricular heart stimulator (), comprising an at least partially electrically conductive housing (), an electrode line terminal for connection of a ventricular defibrillation electrode line () and a terminal for a defibrillation electrode (). According to the invention, the heart stimulator has a far-field electrocardiogram detection unit () which has a first input connected to the terminal for the ventricular defibrillation electrode and has a second input connected to the electrically conductive housing and designed or configured to generate a far-field electrocardiogram on the basis of the electric potentials applied to the two inputs during operation. The inventive heart stimulator also has a far-field electrocardiogram evaluation unit () which is connected to the far-field electrocardiogram detection unit and is designed to detect signal features characteristic of atrial depolarizations in a far-field electrocardiogram generated by the far-field electrocardiogram detection unit.
