RESEARCH OVERVIEW

Abstract

In the Cardio-Rheumatology Department of the Samarkand Regional Multidisciplinary Children’s Clinical Center, we conducted clinical and electrocardiographic analyses of 50 young patients diagnosed with non-rheumatic myocarditis (NM) between 2020 and 2021.

Findings: The study revealed that 86% of young children diagnosed with non-rheumatic myocarditis had a history of acute respiratory infections. The clinical symptoms of non-rheumatic myocarditis were as follows: general weakness (88%), excessive sweating (86%), cough (50%), cyanosis around the lips and nose (58%), and pale, marble-like skin (76%). A muffled heart sound was observed in all patients, while a “gallop” rhythm was detected in 32% of cases. Other findings included tachycardia (80%), arrhythmia (14%), extrasystole (14%), and bradycardia (4%).

ECG changes: Rhythm disorders: Sinus tachycardia (88%), sinus arrhythmia (12%), extrasystole (14%), and sinus bradycardia (6%). Right ventricular hypertrophy was identified in 24% of cases, while left ventricular hypertrophy was observed in 46%. Cardiomegaly was detected in 20% of the patients. Our investigation showed that sinus tachycardia (88%) and weakening of the first heart sound at the apex (72%) were common cardiac signs. In comparison, studies by O.A. Mutaf’yan and Yu.M. Belozerov reported tachycardia in 65% and 62.5% of cases, respectively. However, symptoms such as bradycardia, arrhythmia, and extrasystole were two times less frequent in our study than in those of Yu.M. Belozerov (2014) and O.A. Mutaf’yan (2016).
