[Use of 35-lead mapping of the precordium in the evaluation of left ventricular function in patients after myocardial infarct].
The aim of the investigation was to assess the ejection fraction and regional wall dyssynergy from 35-lead precordial or trunk back ECG taken from 18 consecutive patients after anterior and/or posterior myocardial infarction two months after the acute episode. The percentages of Q waves (% Q) and scores of Q and/or QS waves obtained from 35-lead ECG were compared with the ejection fraction and regional wall dyssynergy recorded by 2D echocardiography. A very good correlation (r = 0.82, SEE = 14.4, p = 0.01) was found between Q% and regional wall dyssynergy in patients with anterior myocardial infarction. There was also a good inverse correlation between ejection fraction and Q% (r = -0.71, SEE = 11.2, p = 0.05) in patients with anterior myocardial infarction. In patients with posterior myocardial infarction no significant correlation was observed by 35-precordial-lead ECG.
