Interpretation of cardiac pathophysiology from pressure waveform analysis: simultaneous left and right ventricular
Catheterization and Cardiovascular Diagnosis
|January 1, 1993
Abstract:
In addition to demonstrating constrictive and restrictive cardiac physiology, simultaneous right and left ventricular pressure measurements can be helpful to identify various aspects of myocardial dysfunction. Intracardiac conduction defects will displace the right ventricular pressure under the left ventricular pressure upstroke and identify differences in the timing of ventricular contraction. Right ventricular dysfunction will also produce abnormal right ventricular pressure waveforms which may overlap left ventricular pressure and contribute to abnormalities in right atrial and ventricular pressure waveforms.
