Detection of the Electrocardiogram Fiducial Points in the Phase Space Using Area Calculation

چکیده
The paper proposes an extension of a known method for heart-beat detection based on ECG reconstruction in a 2D phase space coherent to the delay method to detection of the P-Q-R-S-T characteristic (fiducial) points. The QT Database was used for evaluation and algorithm performance was assessed using sensitivity (Se) and positive predictive value (PPV). Results are 99.19 %, 99.67 % and 94.58 % for Se and 95.02 %, 99.67 % and 94.55 % for PPV for the P points, heartbeats and T points, respectively.
