Time-frequency template matching ECG compression algorithm has an outstanding compression effectiveness and very low distortion of medical data content. Its main disadvantage is the presence of spare patterns as a consequence of poor pattern-to-signal synchronization. This issue is investigated in detail in this paper, and possible solutions are derived: P-onset, QRS-onset and R-max synchronization points are used. Finally these three methods are compared with use of the same data set in order to minimize the number of templates created. Results may be interesting to a wide range of scientist working on a time-frequency representation of a heart’s beat, since it gives several considerations on the representation stability.
