Patent ID: 8827913

Claim:
A system comprising: at least one pressure sensor configured to measure a cardiovascular pressure signal; a medical device configured to measure an electrical depolarization signal of the heart; at least one analysis module configured to: determine a plurality of cardiovascular pressure metrics based on the measured cardiovascular pressure signal, wherein the plurality of cardiovascular pressure metrics includes at least one cardiovascular pressure metric indicative of a timing of at least one cardiac pulse, and at least one of a systolic pressure and a diastolic pressure; and determine a cardiac electrical metric indicative of a timing of at least one heart depolarization based on the measured electrical depolarization signal; and at least one processor configured to: compare the timing of the at least one cardiac pulse to the timing of the at least one heart depolarization; and determine whether to discard the plurality of cardiovascular pressure metrics based on whether the timing of the at least one cardiac pulse and the timing of the at least one heart depolarization substantially agree.
