Prevalence and Etiological Factors of Cardiac Rhythm and Conduction Disorders Among Those Seeking Medical Care From a Cardiologist at the Outpatient Stage

Abstract

The study included 652 patients with persistent rhythm and conduction disturbances who consulted a consultative and diagnostic polyclinic cardiologist for 2 years. Possible etiological factors of arrhythmias occurrence in the examined patients were revealed. In 48 (8.84%) patients no visible causes of rhythm disturbances were revealed. This group of patients underwent magnetic resonance imaging (MRI) of the heart to clarify the nature of arrhythmias. In 32 patients cardiac MRI allowed to determine the probable cause of cardiac rhythm disturbances, and the high frequency of myocarditis signs detection at MRI (⅓ of patients examined) is noteworthy
