Abstract
A non-transvenous implantable cardioverter defibrillator device comprises a generator device comprising a processing circuitry and a shock generation circuitry, and at least one lead comprising a shock electrode for emitting electrical shock pulses externally to a patient's heart. The processing circuitry is configured to identify a sensed ventricular contraction event in a sensed electrocardiogram signal or said processing circuitry is configured to control said shock generation circuitry to generate at least one conditioning pulse for emission by said shock electrode to cause an induced ventricular contraction event. The processing circuitry is further configured to control said shock generation circuitry to generate a fibrillation pulse for emission by said shock electrode at a delay time after said sensed or induced ventricular contraction event in order to induce a cardiac fibrillation state.
