Capture management improvements

摘要

A system is provided that inhibits the delivery of an atrial test pulse during an Atrial Chamber Reset procedure for a medical device, when the delivery of the atrial test pulse would result in adjacent irregular atrial intervals. The system comprises : means for monitoring support cycles; means for determining instability of the support cycles; and means for inhibiting the atrial test pulse when instability is determined. A system is provided that inhibits false positives during an Atrial Chamber Reset procedure for a medical device and comprises a sense amplifier; means for determining when the sense amplifier is stable after delivery of an atrial test pulse; means for inhibiting a positive capture determination when no atrial sense is detected during a loss of capture window after the atrial test pulse when the means for determining determines the sense amplifier has become stable after the initiation of the loss of capture window.
