TIMED DELIVERY OF ELECTRICAL STIMULATION THERAPY

摘要

In some examples, a phase locked loop (PLL) circuit outputs a timing signal having a frequency and phase that is the same as a patient signal that is an input to the PLL circuit. The PLL circuit includes or is coupled to a storage circuit that stores information needed to cause the PLL circuit to maintain the frequency of the timing signal to the same frequency even after the patient signal is not available as an input.

1. A method comprising:
receiving a patient signal indicative of a patient condition; determining a timing signal having a frequency based on the patient signal; during a duration when the patient signal is not being received, outputting the timing signal having the same frequency as the frequency of the timing signal determined based on the patient signal; and controlling delivery of electrical stimulation therapy based on the outputted timing signal during at least a portion of the duration when the patient signal is not being received.
