Abstract
The recovery of the ECG signs of anterior myocardial infarction has been studied in 70 patients. A significant increase in R-wave amplitude and decrease in Q-wave amplitude on 24-lead precordial mapping was observed during one year after infarction. Patients with lower initial heart rate showed a greater recovery of R- and Q-wave amplitudes, as did patients with smaller infarcts, as assessed by peak heat-stable lactate dehydrogenase (LDH).
摘要
对70例前壁心肌梗死患者的心电图表现恢复情况进行了研究。梗死发生后1年内，24导联胸前导联心电图显示R波振幅显著增加，Q波振幅降低。初始心率较低的患者，以及梗死面积较小的患者（通过峰值热稳定乳酸脱氢酶（LDH）评估），R波和Q波振幅的恢复情况更佳。
