Abstract

Remote electrocardiographic techniques were used in outpatient departments of the city clinical hospital (CCH) and the Central district hospital (CDH).

The CDH performed 18,654 electrocardiographic studies (ECS). The automatic conclusion of devices was corrected by specialists of functional diagnostics (FD). In complex cases, an in — depth analysis was performed- an electrocardiogram of 12 leads (ECD -12) — using vectorcardiography (VCD). Pathological ECD syndromes were detected in 5038 individuals (27%). Among the obtained number of ECSs with abnormalities, the most frequently detected were: right leg block ( RLB) — 1029 (20.4%), left ventricular hypertrophy (LVH) — 981 (19.4%), left leg block — 661 (13%), myocardial scarring — 442 (8.7%), extrasystole — 377 (7.4%), atrial fibrillation-310 (6%). The method of VCD was able to clarify 39% of cases of LVH, 40% of cases of focal scarring of the myocardium, and 92% of matches for atrial fibrillation (AF). The use of VCD supplemented the diagnostic capabilities of the remote ECD-12.

According to the results of AF screening by remote single-channel ECD, 69 cases with AF (3.2%) of the total number of examined patients (2,146 people) were detected in the CCH. When analyzing the history, it was clarified that 24 (34.7%) patients had AF for the first time, and 45 (65.3%) individuals had a history of AF.

Remote long-term Holter ECD monitoring system (LTHECD) 27 studies were performed in 20 individuals. Complex, combined heart rhythm disorders were detected in 85%, and ST-T depression was detected in three cases (15%).

Using new electrocardiographic techniques in addition to single-channel ECD, ECD-12 improves the quality of diagnostics of cardiovascular diseases (CVD).
