心电图Ｖ３Ｒ－Ｖ５Ｒ导联ＳＴ段异常抬高是诊断急性右心室心肌梗死（ＲＶＩ）的良好指标，这种抬高发生时间早，持续时间短。有人统计，５０％的病人在１０ｈ内恢复正常，４０％持续２４ｈ。作者报道ＲＶＩ８例ＳＴＶ３Ｒ－Ｖ５Ｒ抬高持续时间均大于２４ｈ，最长的１例达７２?
The abnormal elevation of ST segment of ECG V3R-V5R lead is a good indicator to diagnose acute right ventricular myocardial infarction (RVI). The time of elevation is short and the duration is short. Some statistics, 50% of patients returned to normal within 10h, 40% for 24h. The authors reported RVI8 cases of STV3R-V5R elevation duration were greater than 24h, the longest one case of 72?
