许多CCU常用ECGⅡ或Ⅴ_2~(?)导联监护病人,是因为这些导联能显示P波和心脏节律。若观察心肌缺血是主要目的,则其他导联可能更佳。本文描述了初发AMI住院病人的12导程ECG ST段变化的模式,建议用最佳ECG导联连续做ST段监测以及时发现冠脉再闭塞。方法病人:在1965年1月至1981年12月间住入Du-ke大学医学中心的AMI患者,既往无MI并符合下列条件者:①ECG记录在症状发作后8小时内:
Many CCUs commonly use ECG II or V_2 ~ (?) Leads to monitor patients because these leads show P waves and heart rhythms. If the observation of myocardial ischemia is the main purpose, then the other leads may be better. This article describes the pattern of 12-lead ECG ST segment changes in patients with newly diagnosed AMI inpatients. It is recommended that ST segment monitoring be performed consecutively with the best ECG lead and coronary reocclusion be detected in time. Methods Patients: AMI patients admitted to Du-Ke University Medical Center between January 1965 and December 1981 without previous MI and who met the following criteria: ①ECG recording within 8 hours after symptom onset:
