Abstract:
A method for diagnosing a patient as being at risk for having a cardiovascular pathology, comprising the steps of:a. affixing a non-invasive pressure inducing member and transducer member to the patient,b. elevating the pressure induced by the pressure inducing member to a supra-systolic pressure,c. decreasing the pressure induced by the pressure inducing member over time to a sub-diastolic pressure,d. obtaining a data stream from the transducer member, the data stream including pressure data and pulsation signal data to obtain a series of pulsation signal data waveforms, the waveforms including at least pulsation signal data taken at a supra-systolic pressure and pulsation signal data taken at a sub-diastolic pressure,e. creating a pseudo-aortic wave contour from the obtained supra-systolic waveform data and the sub-diastolic waveform data, andf. diagnosing the patient as having a cardiovascular pathology by comparing the pseudo-aortic wave contour to cardiovascular contours exhibiting known cardiovascular pathologies.
