【Abstract】 The results of serial precordial mapping in 13 patients with anterior myocardial infarction and 2 patients with inferior myocardial infarction and 15 normal subjects as control were reported.The value of the electrocardiographic mapping in assessing infarct size was studied.There was a high positive correlation between ∑ST and CPK(r=0.93,P<0.00l)and a moderate positive correlation between ∑Q and CPK(r=0.60,P<0.05)in acute anterior myocardial infarction.Thus ∑ST and ∑Q can be used as a measure to estimate infarct size.In patients with acute inferior myocardial infarction there was a significant positive correlation between ∑Q in leads Ⅱ Ⅲ aVF and CPK.In chronic myocardial infarction ∑Q may provide a useful electrocardiographic criterion to assess infarct size.更多还原
