Abstract

The exponential fall of the pulmonary pressure curve from its systolic peak to left atrial pressure previously described in the presence of normal intraventricular conduction has been investigated in patients with right bundle-branch block. We have been able to show once more that the pulmonary artery diastolic pressure seeks the left atrial level: when right ventricular systole is delayed the pulmonary artery pressure continues to fall with the left atrial 'x' descent.

摘要

先前在正常室内传导情况下所描述的肺压力曲线从其收缩期峰值降至左心房压力的指数下降情况，已在右束支传导阻滞患者中进行了研究。我们再次证明肺动脉舒张压趋向于左心房水平：当右心室收缩延迟时，肺动脉压力随左心房“x”降支继续下降。
