MOBILE ARRHYTHMIA MONITORING SYSTEM BASED ON MULTIMODAL BIOSIGNAL ANALYSIS: SYNCHRONIZATION OF ECG, PCG, AND PPG

Cardiovascular diseases and, specifically, arrhythmias account for one of the top priority problems of global healthcare systems.Although routine diagnostic procedures, including electrocardiography (ECG) and phonocardiography (PCG), remain cardinal during cardiac activity assessment, the single-modality application restricts diagnostic effectiveness.A mobile system of monitoring arrhythmias by synchronized ECG, PCG, and photoplethysmography (PPG) analysis is developed within this research.Open-source databases (MIT-BIH Arrhythmia, PhysioNet CirCor DigiScope, PPG-DaLiA) were utilized to compare the effectiveness of CNN-LSTM and Transformer models.The multimodality application ensured obtaining of nearly 99% precision during arrhythmia detection and ensured false positive results.The system's capability to function in real-time and to run on mobile devices ensures patient-oriented monitoring.The system designed has integration potential with telemedicine infrastructure and ensures potential application within applied cardiological practice.
