One of the relatively promising new non-invasive methods for predicting sudden coronary death in patients with coronary heart disease and ventricular arrhythmias (VA) may be an assessment of heart rate turbulence (HRT). Given i ts important prognostic role, primarily in patients after MI, the aim of this work was to study the relationship between HRT and cardiovascular remodeling in patients with VA with history of MI and multivessel nature of coronary lesions.Materials and research methods123 patients with history of MI, aged 38 to 76 years (average age 61.0  ± 7.6 years), were included into the study. The multivessel nature of coronary lesions was established based on the results of diagnostic selective coronary angiography. All patients underwent Holter monitoring of the electrocardiogram (HMECG). HRT was determined using two indicators, in accor dance with the guidelines: Turbulence Onset (To, %) and Turbulence Slope (Ts, ms/RRi).ResultsPotentially dangerous ventricular arrhythmias (PDVA) were noted in more than half of the exam...
