Abstract
The present invention is directed toward a pulse generator for detecting that a pulse generator and an implantable lead are properly implanted so that a plurality of automatic features can be automatically turned ON. The automatic features include: automatic sensitivity adjustment; automatic capture adjustment; automatic rate adjustment, and the automatic adjustment of associated rate-responsive parameters; automatic electrode configuration; and the automatic adjustment of other timing parameters. An impedance detector is used to detect that the electrodes are in contact with the body by determining if the lead impedance is within a prescribed range. Redundant sensors, such as a temperature sensor, a shorting plug, or a resistive load could be used to confirm that the electrodes are in contact with the body.
