Abstract

The aim of the study was to determine a complex of informative electrocardiogram (ECG) parameters in revealing coronary artery lesions. Parameters of heart rate variability, QT and T loop morphology were analysed in 199 patients (additional group for QT dispersion analysis only, consisted of 94 patients). Informative signs to determine coronary artery stenosis ≥ 50 % were following: T loop index ≥ 1,5, T loop area ≥ 226 and age ≥ 50 years. QTd and QTcd were not informative parameters for this determination. By applying a complex of parameters (αP – angle between QRS and P vectors; αQRS-T angle between QRS and T vectors; QTc and age) sensitivity for detection coronary artery stenosis has increased to 85 %, specificity to 65 % (r=0,5). Ill. 2, bibl. 11 (in English; summaries in English, Russian and Lithuanian).
