Verification of pressure metrics
First Claim
1. 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.

Abstract
An example system may include at least one pressure sensor configured to measure a cardiovascular pressure signal and another medical device configured to measure an electrical depolarization signal of the heart. The system determines a plurality of cardiovascular pressure metrics based on the measured cardiovascular pressure signal, including at least one cardiovascular pressure metric indicative of a timing of at least one cardiac pulse. The system also determines a metric indicative of a timing of at least one heart depolarization within the measured electrical depolarization signal. The system compares the timing of the at least one cardiac pulse to the timing of the at least one depolarization, and determines whether to discard the plurality of cardiovascular pressure metrics based on whether the timings substantially agree.
