Abstract
A capture-detection cardiac pacemaker wherein a stimulation success can be reliably detected immediately after stimulation pulse output. The cardiac pacemaker according to this invention generally includes at least one stimulation electrode arranged in the region of the heart designed to output stimulation pulses to the heart, and a control unit connected to a pulse generator for controlling the stimulation pulse output. The control unit is connected to a sensor arranged at the myocardium for checking stimulation success at the heart by detecting the myocardial impedance pattern immediately after a stimulation pulse output and still within the diastolic phase of the heart, and controlling the stimulation pulse output based thereon.
