Ea. Berezny et Bm. Lipovetsky, DYNAMICS OF THE CARDIAC-RHYTHM AND ITS VARIABILITY DURING BICYCLE EXERCISE TEST IN PATIENTS WITH ISCHEMIC-HEART-DISEASE, Kardiologia, 37(7), 1997, pp. 29-32
R - R intervals and standard deviations of R - R intervals were measur
ed in 21 patients with ischemic heart disease at maximal work load dur
ing bicycle exercise test and after its termination. Undulating change
s of magnitude of these parameters were found in some patients during
postexercise rest. Presence or absence of these sinuous fluctuations a
llowed to assess individual reaction to fulfilled exercise.
