Performance evaluation of heart rate turbulence detection using an extended IPFM model

Abstract:

In a previous study, we presented a new approach to characterize heart rate turbulence (HRT). An HRT detector was developed which involved a HRT test statistic T(x), being based on Karhunen-Loève (KL) basis functions. The purpose of the present study is to evaluate the performance of T(x) on simulated data and compare to that of turbulence onset (TO) and turbulence slope (TS). Three different simulations were performed for the purpose of studying the influence of signal-to-noise ratio (SNR), QRS jitter, and ECG sampling rate. The results show that T(x) performs strikingly better in all simulations.
