POSSIBILITIES OF THE METHOD OF REMOTE ELECTROCARDIOGRAM SELF-REGISTRATION FOR DETECTING SYMPTOMIC HEART RHYTHM DISORDERS

Highlights

• The results of a one-time study are covered. The possibilities of self-registration of an electrocardiogram by patients for diagnosing symptomatic cardiac arrhythmias in everyday conditions have been demonstrated.

Aim. To study the possibilities of remote monitoring of an electrocardiogram by self-registration method for the diagnosis of paroxysmal cardiac arrhythmias and verification of the genesis of subjective complaints.

Methods. The study was conducted with Russian-made devices. 95 patients participated in the study. The inclusion criterion was referral to remote monitoring of an electrocardiogram in order to verify cardiac arrhythmias. A special memo was developed for the patients. The receiving server was prepared. Patients were trained for ECG self-registering at home, ECG Dongle equipment was provided.

Results. An open single-center single-stage (cross-sectional) study was conducted. The average age of the patients was 44 ± 17.1 (Me = 45 [30.0; 58.0] Me [Q25; Q75]). The possibilities of remote monitoring of an electrocardiogram by the self-registration method for the diagnosis and verification of paroxysmal cardiac arrhythmias have been highlighted. The methodology and features of the patient’s organization of examination at the outpatient stage are described in detail. Statistical processing of 332 ECGs was performed. Symptomatic cardiac arrhythmias, including paroxysmal ones, were verified in 43 subjects. The most common causes of symptomatic ECG registration at home were atrial (17.9 ± 4.2%) and ventricular extrasystole (10.7 ± 3.4%). Paroxysmal cardiac arrhythmias (atrial fibrillation, atrial tachycardia, paroxysms of reciprocal atrioventricular tachycardia, orthodromic atrioventricular tachycardia in WPW syndrome) were detected in 16 patients (19.0 ± 4.3%).

Conclusion. The method can be used if the patient is an experienced user of a smartphone. In order to obtain high-quality research results, careful patient instruction, e-mail and mobile Internet access at the monitoring object are required.
