Time-frequency analysis compensating missing data for Atrial Fibrillation ECG assessment

Wimalaguna Kodituwakku, Sandun; Kennedy, Rodney; Abhayapala, Thushara


We propose a novel algorithm for temporal tracking of the fibrillatory frequency for Atrial Fibrillation (AF) ECG. Both Atrial activity extraction and fibrillatory frequency tracking are combined into a single algorithm and analytical expressions are derived for final time-frequency distributions, thus the proposed method is computationally efficient. It can also serve the general purpose of time-frequency analysis of a non-stationary signal with missing or corrupted data segments. The method...[Show more]
