Abstract:
1. A medical device capable of generating a pacing pulse train associated with delivery of a high-energy pulse, comprising: means for delivering the pacing pulse train to a chamber of a patient's heart; means for generating evoked response data associated with the delivered pacing pulse train; means for determining, in response to the generated evoked response data, whether one or more predetermined pacing pulse train requirements are satisfied and identifying the pacing pulse train as being valid in response to the one or more requirements being satisfied; and means responsive to the identification of the pacing train as valid for delivering the high-energy pulse to the chamber of the patient's heart at a predetermined delay following delivery of the pacing pulse train, wherein the means for determining whether one or more predetermined pacing pulse train requirements are satisfied compares the generated evoked response data, determines a temporal consistency of the compared evoked response data, determines whether time intervals associated with a plurality of evoked responses corresponding to the pacing pulse train differ by more than a predetermined time period, wherein the means for determining whether one or more predetermined pacing pulse train requirements are satisfied determines one or more locations of temporally inconsistent evoked response data along the delivered pacing pulse train, and wherein the means for determining whether one or more predetermined pacing pulse train requirements are satisfied assigns one or more weighting factors in response to the determined one or more locations.
