Popis:	Changes in pre-ejection period (T) and ejection time (E) during the post-extrasystolic beat, as compared to regular sinus rhythm, as well as ratios thereof can be useful for the assessment of myocardial activity and reserve in patients with heart diseases. The potentiation index, proposed by the authors, i. e. the ratio between the difference between absolute delta E-delta T changes and the absolute change in Weisler's coefficient (delta T/E), has the highest value in this respect.
