Abstract
An implantable cardiac stimulation device provides bipolar pacing and bipolar autocapture. If a measured bipolar electrode configuration capture threshold is too high, an impedance measuring circuit measures the impedance of the bipolar electrode configuration to determine a possible lead failure. If the bipolar electrode configuration impedance is within a normal range, bipolar pacing is continued in a manner which assures continued capture of the heart. If the bipolar electrode configuration impedance is outside of the given range of impedances, the device is switched to unipolar pacing in a manner which insures capture of the heart and notification of the need for a physician consultation.
