Abstract :
The correlation between the parameters reflecting ventricular repolarization inhomogeneity and the results of programmed ventricular stimulation was assessed in 58 post-myocardial infarction patients. Registration of increased QTc interval duration and QT and QTa interval dispersion in patients with high risk of sudden death as compared to the patients without it according to the results of programmed ventricular stimulation (469.5±43.2 and 435.5±29.6 ms, 60.2±23.6 and 43.8±11.3 ms, 56.71±27.0 and 33.7±14.5 ms, respectively) demonstrate the efficacy of this non-invasive method in identification of high-risk subgroup of post-myocardial infarction patients
