[Graphic analysis of electrocardiograms with the exercise test].

The effort ECG is one of the most useful and most commonly employed methods for the early diagnosis of coronary disease in patients with a normal ECG at rest. Perfection of a computerised method for this purpose is reported. An effort test is run on the cyclergometer and the ECG is read for 2 min at rest, during the test, and for 3 min afterwards. The chest bipolar leads are used. The diagnostic possibilities are greatly improved by computerisation and interpretation of the effort ECG.
