Objective: Evaluation of obesity influence on ventricular activity dispersion parameters. Material and method: Fifty chronic myocardial infarction patients, divided in two groups: obese and normal weight patients, underwent electrocardiographic investigation to calculate the heart rate corrected (HRC) QT interval variability indices: QTdc (HRC QT dispersion), JTdc (HRCJT dispersion), QRSdc (HRC QRS dispersion), and the average values of the QT (QTm) and JT (JTm) intervals.

Results: Obesity increases significantly only QRS dispersion (p=0.0027), but not the other variability QT indices.

Conclusions: Intraventricular conduction is affected in obese coronary patients and QRSdc should be adjusted to the body mass index in coronary patients.
