体表心电图V1导联P波终未电势(PTFV_1)临床意义早于1964年由Mor(?)s首先报告。称为Morris指数。其后,国内外对PTFV_1在冠心病和急性心肌梗塞的诊断、预后估计和左室泵功能判定进行大量研究,肯定了其临床意义。本文通过对1989～1992年我们观察的154例急性心肌梗塞(AMI)的PTFV_1分析,探讨PTFV_1的临床意义。 154例AMI中,男115例,女39例,年龄在40岁以下5例,41～60岁82例,60岁以上67例,平均年龄58.4岁。 以PTFV_1≥—0.03mms为PTFV_1正常组,计86例(55.84%),其中男72例,女14例;40岁以下4例,41～60岁45例,60岁以上37例。以PTFV_1<—0.03mms为PTFV_1异常组,计68例(44.16%),其中,男43例,女25例;40岁以下1例,41～60岁37例,60岁以上30例。
The clinical significance of P wave end potential (PTFV_1) on the surface ECG V1 lead was first reported by Mor (?) S in 1964. Known as the Morris index. Subsequently, a large number of studies on the diagnosis, prognosis and left ventricular pump function determination of PTFV_1 in coronary heart disease and acute myocardial infarction both at home and abroad affirmed its clinical significance. In this paper, from 1989 to 1992 we observed 154 cases of acute myocardial infarction (AMI) PTFV_1 analysis of the clinical significance of PTFV_1. There were 115 males and 39 females in 154 cases of AMI, 5 cases under 40 years of age, 82 cases 41 to 60 years old and 67 cases over 60 years old, with an average age of 58.4 years. There were 86 cases (55.84%) with PTFV_1≥-0.03mms in PTFV_1 normal group, including 72 males and 14 females; 4 patients under 40 years old, 45 cases 41 to 60 years old and 37 cases over 60 years old. There were 68 cases (44.16%) with PTFV_1 <-0.03mms as the abnormal group of PTFV_1, including 43 males and 25 females; 1 case under 40 years old, 37 cases 41 to 60 years old and 30 cases over 60 years old.
