Development of advanced method for heart ventricular fibrillation detection
Introduction. The article deals with modern algorithms for detecting ventricular fibrillation such as TCI, VF, SPEC, CPLX, HILB. The best sensitivity among them is the HILB algorithm, based on the construction of phase-space plot using the Hilbert transform.
Results. It was founded opportunities to improve the specificity of the HILB algorithm by introducing additional features of the phase-space plot, such as the center of mass and the standard deviation of points. The software for analyzing the one lead ECG signal was developed. The software implements preliminary filtration of the signal and the proposed method for detecting ventricular fibrillation.
Validation of the method was performed based on well-known open databases such as MIT-BIH Arrhythmia Database, American Heart Association Database (AHA), Creighton University Ventricular Tachyarrhythmia Database (CU). Sensitivity obtained for CU database is 83% and positive predictive value is 93%, for MIT-BIH — 100% and 100%, for AHA — 90% and 98%, respectively.
Comparison of results with TCI, VF, SPEC, CPLX and HILB algorithms was performed. Sensitivity and positive predictive value of the proposed method are better than known algorithms.
