We present a new method for obtaining the pressure-volume area (PVA) as defined by Suga. The method allows calculation of the PVA from pressure and flow waveforms of ejecting beats and requires only one isovolumic ventricular contraction performed at any end diastolic volume.
我们提出了一种获取由须贺定义的压力-容积面积（PVA）的新方法。该方法允许根据射血搏动的压力和流量波形计算PVA，并且仅需要在任何舒张末期容积下进行一次等容心室收缩。
