POSSIBILITIES OF MAGNETIC RESONANCE IMAGING FORDIAGNOSTIC ETIOLOGIC FACTORS IN THE OCCURRENCE OF ARRHYTHMIASOF THE MILITARYS

Abstract

Surveyed 652 patients with persistent violations of rhythm who applied to the cardiologist of the center of VMA during the 2 years. Of 652 patients was highlighted that some patients (543), in which the rhythm disturbance with daily monitoring Holter ECG were significant, that is, the number of ventricular and supraventricular extrasystoles exceeded the acceptable rate. These patients were divided into 3 groups to assess the frequency of ventricular and supraventricular arrhythmias: Group 1: patients with a primary rhythm disturbance according to the type of ventricular arrhythmia — 96 people (80 men and 16 women). Their average age was 68 years (18–89). Group 2: patients with a primary rhythm disturbance according to the type of supraventricular extrasystole — 343 (271 male and 72 female). Their average age was 67 years (17–83). Group 3: patients with complex arrhythmias (supraventricular and ventricular premature beats) — 106 patients (94 male and 12 female). Their average age was 65 years (18–87). Compulsory medical examination for the patient included a complete medical examination with the filling of a formalized medical history; laboratory studies (clinical blood analysis, biochemical blood — potassium, sodium, magnesium, chlorine, glucose, lipid spectrum, creatinine, total protein, coagulation profile, thyroid hormones T3, T4, TTG); instrumental examinations (ECG, daily monitoring of Holter ECG, radiography of the chest, echocardiography). Identified possible etiologic factors in the occurrence of arrhythmias in patients. The main etiological factors of arrhythmia were: ischemic heart disease (IHD), arterial hypertension (AH), heart failure II–IV FC, the presence of sclerodermatineae acquired heart disease, cardiomyopathy, diabetes mellitus type II, thyroid disease (hyperthyroidism and hypothyroidism), cancer, history of pulmonary embolism (PE), acute violations of cerebral circulation (cerebral vascular accident), coronary artery bypass graft (CABG), family history of coronary heart disease, overweight, menopause. The main provoking factors according to the survey patients were: alcohol abuse and Smoking, daily repeated use of strong tea and coffee, psycho-emotional and physical stress, infectious diseases.48 surveyed (8,84%) did not identify any apparent cause arrhythmias. This group of patients underwent heart MRI for the purpose of clarifying the nature of the arrhythmias. In 32 patients performing MRI of the heart has allowed to establish probable cause rhythm disturbances, draws attention to the high frequency of detection of MR-signs of myocarditis (1⁄3 of the surveyed).
