Abstract
Introduction. The development of devices capable of effectively analyzing electrocardiosignals (ECS) is a relevant and significant task, particularly in enhancing their functionality. Currently, there are no single-channel devices that can evaluate ventricular late potentials (VLPs)—low-amplitude components with predictive value. The aim of this study is to assess the feasibility of detecting VLPs in ECS recorded using a single lead. Materials and methods. For this study, Z-lead ECS signals were selected. A total of 271 signals were analyzed using two approaches: the standard method for detecting VLPs (Simson’s method) and a modified version of this method adapted for Z-lead ECS (the proposed algorithm). To improve analysis accuracy, smoothing techniques and an additional correlation-based processing algorithm were applied. Results. The standard approach detected VLPs in 46 cases, whereas the proposed algorithm identified 80 cases. This may indicate a potential advantage of the proposed algorithm, particularly since the analyzed signals exhibited characteristics associated with myocardial infarction. The probability of a correct decision when testing the algorithm exceeded 73%. Conclusion. The proposed algorithm effectively detects VLPs in Z-lead ECS. These findings may contribute to the development of single-channel ECS analyzers.
