A case of inferior myocardial infarction complicated by severe arrhythmias and right heart failure is presented. Radionuclide studies performed near the acute phase and one month later illustrate the reversibility of right heart dysfunction caused by infarction. Signs of right ventricular involvement in acute inferior myocardial infarction are noted in about 40% of cardiac blood-pool studies: right ventricular dilatation with a significantly decreased ejection fraction, and ventricular wall motion abnormalities. Follow-up studies in the recovery period show good recovery of right ventricular function.
本文报告1例下壁心肌梗死合并严重心律失常及右心衰竭的病例。在急性期及1个月后进行的放射性核素研究表明，梗死所致右心功能障碍具有可逆性。在约40%的心血池研究中可观察到急性下壁心肌梗死时右心室受累的征象：右心室扩张，射血分数显著降低，以及室壁运动异常。恢复期的随访研究显示右心室功能恢复良好。
