实验狗于结扎冠状动脉后,出现ST段抬高的部位,以及心肌中肌酸磷酸激酶值的降低,提示ST段的抬高程度直接和心肌缺血或坏死的范围有关。因此有人连续数天,每天用多导联放在患者前胸,计算其每天ST段抬高数的总和值,以测定心肌缺血的严重度及范围。本文对26例正常人(40～84岁,平均年龄55岁)及19例急性心肌梗塞患者(30～72岁,平均年龄53岁,其中14例属穿壁性,5例属非穿壁性或心内膜下心肌梗塞),用48个导联置于胸前区,在每一肋间自胸骨中线右侧开始直到左腋后线,分置8个导联,共作6个肋间。用TP作为基线,测定ST段抬高的程度(1毫伏=20毫米,纸速为25毫米/
Experimental dogs in the coronary artery ligation, there ST segment elevation, and decreased myocardial creatine phosphokinase value, suggesting that the extent of ST segment elevation and myocardial ischemia or necrosis range. So some people for several days, every day with multi-lead on the patient’s chest, calculate the sum of daily ST-segment elevation to determine the severity and extent of myocardial ischemia. In this paper, 26 normal people (40-84 years old, mean age 55 years) and 19 cases of acute myocardial infarction (30-72 years old, mean age 53 years old, of which 14 cases were transmural and 5 cases were non-transmural Or subendocardial myocardial infarction), with 48 leads placed in the chest area, in each intercostal line from the right side of the midline of the sternum until the left axillary line, the separation of the 8 leads, a total of 6 intercostal space . Using TP as a baseline, the extent of ST elevation was determined (1 millivolt = 20 mm, paper speed 25 mm /
