[Comparative characteristics of intervals Q-T and J-T in patients with unstable angina and myocardial infarction based on standard electrocardiography and electrocardiotopography].

We examined 94 patients (mean age 61,7 +/- 9,9 years) with unstable angina and myocardial infarction. Comparative characterization of prognostic value of Q-T and J-T intervals obtained at conventional 12-lead electrocardiography and 35-lead electrocardiotopography in assessment of risk of repetitive coronary events during follow up for 1 year was carried out. It was found that prolongation of maximal corrected Q-T interval obtained by electrocardiotopography at admission had greater prognostic significance for assessment of risk of unfavorable outcome. Increase of this parameter of Q-T interval was not related to augmentation of area and degree of subendocardial myocardial damage and left ventricular systolic dysfunction.
