title: [Variability and stability of ventricular extrasystole in patients with a history of myocardial infarction].
abstract: Changes in ventricular extrasystole were examined using 3 sessions of 24-hour Holter ECG monitoring in 304 myocardial infarction survivors. The highest reproducibility was shown by the maximum ventricular extrasystole gradations 1, 3, 4b, according to the Lown-Wolff classification. Evidence of possible transformation of the maximum ventricular extrasystole gradations at repeated prolonged ECG monitoring sessions is presented.
