Abstract
A method for determining a patient's left ventricular pressure waveform without placement of a catheter inside the left ventricle, including converting the patient's ejection phase waveform of the peripheral arterial pressure by using a standardized ejection correlation curve, and converting the filling phase waveform of the pulmonary capillary wedge pressure by using a standardized filling correlation curve, into two portions of the left ventricular pressure waveform, and then connecting the two portions together with two straight lines to complete the left ventricular pressure waveform.
