Abstract

Proposed is a piecewise-uniform resampling technique for an ECG signal. Different waves of a heartbeat signal are resampled at different rates. The proposed method was tested on a large number of ECG signals with high and low sampling resolutions. It has been found that the piecewise-uniform resampling method helps to improve the morphology alignment in general. This improvement is significant (e.g. 206%) when the durations of different heartbeats vary largely. Improved morphology alignment of resampled heartbeats could be useful in many applications such as cardiovascular engineering and ECG-based biometrics.
