Analysis of Electrocardiosignals by Z Lead on Presence of Low-Amplitude High-Frequency Components

Purpose of this study is effective registration of low-amplitude high-frequency components with predictive value - ventricular late potentials (VLPs) - in heart signals (ECS) by single Z lead. 206 signals were preliminary evaluated to detect VLPs by Simson’s method. VLPs were detected in 30 signals. In this study Simson’s algorithm was applicated to signals by Z lead. To realize that algorithm R-peak of heartbeat signal was used as synchronization point. VLPs were detected in 52 signals using designed algorithm. Originality: new approach to detect VLPs by single Z lead was designed. Opportunity to detect VLPs in signals by Z lead was evaluated: it is possible to register VLPs by single Z lead. Results of this research are practically significant: they can be integrated in onboard communication equipment related with telemedicine.
