ECG pattern analysis for high sampling rate acquisition

In this article is presented an analysis on ECG signal, acquired with 10 to 100kHz sampling rate. This approach allows highlighting new items regarding the waves patterns of ECG signal. At a deeper detailing of the recorded signal can be observed new patterns of P wave, the extinction of T and S waves as peaks and their replacement with curves. These peaks depend on the noise level and the slopes of the T waves. Also, in all ECG recordings can be observed an important variation of the P, S and T waves from one complex to another.
