The ECGs of 70 consecutive patients hospitalised for a first transmural myocardial infarction (MI) (28 anterior, 42 posterior) were analysed prospectively and systematically during the acute phase. Endocavitary electrophysiological studies (EEP) were performed on the 21st day. The following conclusions were drawn: --Sinus bradycardia in the acute phase was observed in 18 cases (26 p. 100). Its cause is uncertain and its occurrence has no relation to the site of infarction. The single case of sinoatrial block (SAB) was recorded in a patient with a posterior MI. --EEP were normal in 18 patients who had sinus bradycardia during the acute phase; EEP was clearly pathological in the case with SAB. --There was no statistical difference in the incidence of pathological EEPs (p greater than 0,05) in anterior (4 out of 28 patients) and posterior (5 out of 42 patients) MI.
对70例因首次透壁性心肌梗死（MI）住院的患者（28例前壁梗死，42例后壁梗死）在急性期进行了前瞻性、系统性的心电图分析。在第21天进行了心腔内电生理研究（EEP）。得出以下结论：——急性期窦性心动过缓见于18例（占26%）。其病因不明，其发生与梗死部位无关。1例窦房阻滞（SAB）记录于1例后壁心肌梗死患者。——急性期有窦性心动过缓的18例患者EEP正常；SAB患者的EEP明显异常。——前壁心肌梗死（28例患者中有4例）和后壁心肌梗死（42例患者中有5例）患者中病理性EEP的发生率无统计学差异（p＞0.05）。
