摘要:
Devices, systems, and methods automatically detecting anomalous waveforms and eliminating these waveforms from physiologic measurements are disclosed. For example, in some instances a method includes collecting a pressure data from an intravascular device positioned within the vessel of the patient, the pressure data including a pressure waveform for each cardiac cycle of the patient; comparing the pressure waveform for each cardiac cycle of the patient to a reference pressure waveform to identify an anomalous pressure waveform; and calculating a pressure ratio utilizing the pressure data from the intravascular device, wherein data from the anomalous pressure waveform is excluded from the calculation.
