A 48-year-old man with severe pectus excavatum presented with incapacitating supraventricular tachycardia, paroxysmal in nature and invariably provoked by exercise. During mild supine leg exercise on a bicycle ergometer an abnormal increase in right heart pressures, particularly in the right atrium, was observed, followed immediately by supraventricular tachycardia. The latter was also shown during upright exercise on a treadmill. Operative correction of the deformity led to complete relief from the dysrhythmia and a normal haemodynamic response on exercise. The pre- and post-operative studies lend support to the conclusion that the sternal depression was the most likely cause of the cardiac abnormality.
一名48岁患有严重漏斗胸的男性出现发作性、运动诱发的、使人衰弱的室上性心动过速。在自行车测力计上进行轻度仰卧腿部运动时，观察到右心压力异常增加，尤其是右心房压力，随后立即出现室上性心动过速。在跑步机上进行直立运动时也出现了室上性心动过速。手术矫正畸形后，心律失常完全缓解，运动时血流动力学反应正常。术前和术后的研究支持了胸骨凹陷最有可能是心脏异常原因的结论。
