Abstract
An implantable pacemaker having a unipolar/bipolar lead interchangeability includes lead impedance measuring capability for automatically measuring lead impedance, initiated by the occurrence of predetermined events, such as whenever a programming change is made, whenever capture fails to occur in response to an applied stimulation pulse, whenever the leads are changed, and whenever a significant change of lead impedance is otherwise detected. If a proper impedance measurement is not sensed for a programmed configuration, additional impedance measurements for other possible configurations are made in an ordered sequence in order to determine if an improper lead has been implanted or if a electrode has broken. If an operable configuration is found, signified by a measurement of impedance as expected, the pacemaker continues operation in that configuration, thereby assuring that capture can continue to occur until such time as the problem which has been detected can be corrected.
