1. An implantable cardioverter-defibrillator system (ICDS) comprising:
at least one stimulation unit; at least one detection unit; at least one control unit;
wherein the at least one control unit is connected with the at least one stimulation unit, andwherein the at least one control unit is connected with the at least one detection unit; at least two electrode poles connected to the at least one detection unit, wherein the at least two electrode poles are in contact with body tissue; at least one high voltage capacitor that is configured to be charged by at least one charging unit, wherein the at least one high voltage capacitor is connected to the at least one control unit and wherein the at least one charging unit is connected to the at least one high voltage capacitor;
wherein the at least one charging unit is connected to one or more of the at least one control unit and the at least one stimulation unit, andwherein one or more of the least one control unit and the at least one stimulation unit is is configured to initiate the charging of the at least one high voltage capacitor by the at least one charging unit; wherein the at least one detection unit is configured to process physiological signals received from the heart and to detect the presence of an acute ventricular tachycardia or fibrillation, wherein said physiological signals comprise one or more of accelerations, sounds, and electric signals comprising one or more of bioelectric potentials, currents and impedances; wherein at least one of the at least two electrode poles is configured to sense electric signals; wherein the physiological signals or data representing said physiological signals are transmitted to the control unit by the detection unit utilizing an output signal; wherein the at least one control unit is configured to respond to the output signal of the at least one detection unit and to actuate the at least one stimulation unit to emit stimulation pulses or a train of stimulation pulses forming an antitachycardic therapy (ATP), or to emit an antitachycardiac defibrillation shock; wherein the at least one control unit is further configured to actuate an ATP prior to actuating an antitachycardiac defibrillation shock; wherein the charging of the at least one high voltage capacitor is initiated either prior to actuating an ATP or during emitting an ATP or after emitting an ATP; wherein the at least one control unit is configured to actuate the at least one stimulation unit dependent on preset criteria or an adaptive criteria;
wherein the preset or adaptive criteria is different when actuating an ATP and when actuating an antitachycardiac defibrillation shock, and,wherein the preset or adaptive criteria when actuating an ATP is from the physiological signals or data representing said physiological signals a detection of a first number of events M out of a first total number of events N criteria with an M/N quotient, and the preset or adaptive criteria when actuating an antitachycardiac defibrillation shock is from the physiological signals or data representing said physiological signals a detection of a second number of events X out of a second total number of events Y criteria with an X/Y quotient, wherein at least X>M and Y>N. |
