Implantable cardiac stimulator, with chamber stimulation unit connectable to left/right ventricular stimulation electrode to generate/deliver chamber stimulation pulses for stimulation of ventricle; ventricular sensing unit (VSU) to detect respective chamber contraction and deliver ventricular sensing signal when chamber contraction detected; optional atrial stimulation unit, connectable to atrial stimulation electrode to generate atrial stimulation pulses to stimulate atrium; atrial sensing unit, to detect atrial contraction, deliver atrial sensing signal indicating respective atrial event; tachycardia detection unit, connected to VSU to detect and categorize ventricular/supraventricular tachycardia; treatment control unit (TCU), triggers chamber stimulation unit to deliver antitachycardiac stimulation (ATP); analyzer unit, connected to atrial sensing unit and TCU. Analyzes atrial events from sensing unit before/during/after delivering antitachycardiac stimulation for atrial rhythm pattern during ventricular ATP by comparison atrial rhythm pattern immediately before ATP and to trigger TCU as function of ATP response signal representing comparison result for selection of the following antitachycardiac treatment.

Antitachycardiac stimulator

The present invention relates to an implantable battery-operated electrostimulation device (), particularly for stimulating a heart, having a telemetry unit () for wireless data transmission between the electrostimulation device () and an external device (), a control unit (), which is connected to the telemetry unit () and is implemented to trigger a telemetric data transmission, a battery () for the power supply of the electrical components of the implant, such as the telemetry unit and the control unit, and a self-test unit, which is implemented to register the functional state of the electrostimulation device and independently detect acute or imminent malfunctions, the self-test unit () being connected to the control unit and the control unit being implemented to trigger a data transmission using data on the functional state of the electrostimulation device if an acute or imminent malfunction is detected.
