Algorithms for ECG analysis in mobile cardiac monitoring system

This work presents algorithms and software for the automated ECG processing and analysis in the mobile cardiac monitoring system based on smartphone. The key component of the system is portable ECG acquisition device realized in the form of smartphone case. The registered ECG is preprocessed by the smartphone software and is transferred further via Internet to the cloud service where additional computer analysis of the signal is implemented and the ECG and its analysis results are stored in the database. The data from the cloud service are available both to the patient and to his doctor. The following main functions of ECG analysis are realized by the algorithms: pacemaker spikes detection, heart rate control, cardiac arrhythmia recognition and heart rate variability analysis. Several modifications of the ECG acquisition device for iPhone series 5/5S, 6/6S are in batch production now in the frames of CardioQVARK project. At the same time the data from the system database are used permanently for the further enhancement of the algorithms.
