Brief summary
The article substantiates the use of magnetic resonance imaging to identify the nature of idiopathic arrhythmias, which allows to establish the likely cause of heart rhythm disturbances in patients. The study involved 545 patients with significant cardiac arrhythmias. Three groups were formed: Group 1: patients with rhythm disturbances according to the type of frequent ventricular premature beats - 96 people (16 women and 80 men), Group 2: patients with rhythm disturbances according to the type of frequent supraventricular extrasystoles - 343 people (72 women and 271 men), 3rd group: patients with combined cardiac rhythm disturbances (supraventricular and ventricular extrasystoles) - 106 patients (12 women and 94 men). Instrumental examinations included: echocardiography, electrocardiography, 24-hour Holter ECG monitoring, chest X-ray. magnetic resonance imaging of the heart with contrasting, which allowed to establish the probable cause of cardiac arrhythmias (2/3 of all examined). The use of magnetic resonance imaging increases the possibility of early diagnosis of myocarditis.
