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.
除了可显示缩窄性和限制性心脏生理学特征外，同步测量左右心室压力有助于识别心肌功能障碍的各个方面。心内传导缺陷会使右心室压力在左心室压力上升期下移，并识别心室收缩时间的差异。右心室功能障碍也会产生异常的右心室压力波形，这些波形可能与左心室压力重叠，并导致右心房和心室压力波形异常。
