临床上一直认为,根据急性心肌梗塞(MI)病人心电图(ECG)上有无异常Q波出现,可以大致鉴别MI的两种病理类型,即穿壁性MI(TI,即Q波MI)和非穿壁MI(NTI,即无Q波MI、内膜下MI)。虽然ECG改变与病理类型并不完全一致,但多数学者仍认为,ECG不失为粗略判断MI病理类型的简易临床方法。 关于两类MI的临床差异,一直是MI研究领域中较受重视的课题之一。50～70年代初期,大量临床研究的结论是,NTI为良性MI,病人的临床经过和预后较TI为好,因而没有给予NTI以足够的重视。上述观点至
Clinically, it has been considered that the presence or absence of abnormal Q waves on the ECG of an acute myocardial infarction (MI) can roughly identify two pathological types of MI, that is, transmural MI (TI, Q wave MI) and non Wall MI (NTI, that is, Q-wave MI, subendocardial MI). Although ECG changes and pathological types are not exactly the same, but most scholars still believe that ECG may be a rough and simple method to determine the pathological type of MI clinical. The clinical differences between the two types of MI have been one of the more important topics in MI research. From the early 1950s to the early 1970s, a large number of clinical studies concluded that NTI was benign MI, and that the clinical course and prognosis of patients were better than that of TI and thus did not give enough attention to NTI. The above point of view to
