Optimizing the discrete representation of the electrocardiogram the particular signal sections of a heartbeat show different diagnostic importance and different local bandwidth, this irregularity is correlated with the positions of waves in an electrocardiogram, that are easily detectable by the software of today,  optimizing the discrete representation of the ECG consists in local adaptation of sampling frequency and quantization level performed stepwise or smoothly  [18],[25],[28],[29],[30],[35],[47],[48],[49]
