摘要
Signal Averaged Electrocardiography (SAECG) is a technique widely used as an alternative to improve signal to noise ratio (SNR), but sometimes patient's physiology may alter the characteristics of quasi-steady heartbeats that are assumed in the averaging. This paper evaluates the noise as a parameter for measuring the alignment heartbeats by Derivative Dynamic Time Warping (DDTW) and using Piecewise Linear Approximation (PLA) as well. The records were taken from a group of healthy individuals and the results show that the number of heartbeats averaged necessary to improve the SNR is less than the traditional method.
