Lvedp waveform
WebPulmonary artery diastolic pressure (PAD) is often used to estimate left ventricular end-diastolic pressure (LVEDP) when artifact, respiratory variation, or technical difficulties make the wedge pressure difficult to identify on the waveform. To determine which point on the PAD waveform best estimat … WebE/e’ ratio and LVEDP. By dividing the peak E-wave velocity by the peak e' velocity, left ventricular end-diastolic pressure (LVEDP) can be estimated. This is the E/e' ratio and it …
