Pulmonary hypertension significantly changes biventricular anatomy and physiology, frequently evolving to clinical deterioration and right ventricular failure. The case of a woman developing atrial arrhythmias complicating dipyridamole stress in concomitance with scintigraphic "D-shaped" left ventricle is briefly reported. Although rare, our finding may suggest that nonselective vasodilators should be used with caution in this clinical setting.
肺动脉高压会显著改变双心室的解剖结构和生理功能，常常发展为临床病情恶化和右心室衰竭。本文简要报道了一例女性患者，在双嘧达莫负荷试验时出现房性心律失常，同时伴有闪烁扫描显示“D形”左心室。尽管这种情况罕见，但我们的发现可能提示，在这种临床情况下使用非选择性血管扩张剂应谨慎。
