摘要

老年患者表现为疲劳、用力性呼吸困难、用力性胸闷和心悸。心肺运动试验(CPET)显示双心室充盈压低和外周氧提取不良是导致呼吸困难的原因,与负荷前衰竭一致。倾斜试验显示体位性心动过速综合征(POTS),神经病变形式。

Case 37: Severe Dyspnea and Preload Failure
An older patient presents with fatigue, exertional dyspnea, exertional chest tightness, and palpitations. Cardiopulmonary exercise testing (CPET) showed low biventricular filling pressure and poor peripheral oxygen extraction as a cause of dyspnea, consistent with preload failure. Tilt test demonstrated postural tachycardia syndrome (POTS), neuropathic form.
