[Differences in reference values in 2-dimensional echocardiography in men and women].

A total of 126 voluntary blood donors (90 men, mean age 30 +/- 0.5 yrs, and 36 women, mean age 34 +/- 0.5 yrs) were examined to establish standards for two-dimensional echocardiography.

[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.
