Abstract:
1. A method for delivery of electrical therapy to a patient by a medical device comprising: activating the medical device; performing a first analysis of a first set of data signals from the patient sensed by the medical device; if the first analysis shows that the first set of data signals meets a first criterion, commencing charging of an energy storage device upon completion of the first analysis; performing a second analysis of a second set of data signals from the patient regardless of the outcome of the first analysis; and if the second analysis determines that the second set of data signals meet a second criterion different from the first criterion, charging the energy storage device upon completion of the second analysis to a charge level at which the device is capable of delivering the therapy and delivering the therapy regardless of the outcome of the first analysis, wherein the first criterion indicates a degree of probability that the second analysis will result in delivery of the therapy.
