Abstract. Predicting adverse outcomes in people who have suffered a myocardial infarction remains a serious and unresolved problem, which pushes researchers to search for new technologies. One of the relatively promising new noninvasive methods for predicting sudden coronary death in patients with coronary artery disease and ventricular arrhythmias may be a noninvasive assessment of myocardial electrical instability. Taking into account its important prognostic role, primarily in patients with ventricular arrhythmia who have suffered a myocardial infarction and have a multivessel character of coronary lesion, the purpose of this work was to study the characteristics of QT interval variance and heart rate variability in this category of patients.
Keywords: QT interval variance, heart rate variability, ventricular arrhythmia, myocardial infarction, sudden coronary death.
