Abstract
A new method is presented, different from usual methods, for the discussion of the
results of computer ECG measurement programs, based on a new graphical evaluation
method. The proposed “scatter-graphs” both highlight the main program results and
facilitate the comparison between various wave-recognition algorithms. They allow
the distinction between the reliability of an algorithm, which is its capacity to
provide a maximum of measurements with a minimum amount of errors, and its precision,
i.e., the standard deviation of the differences between its point estimates and the
reference.
The method proves to be a powerful tool for the discussion of individual, as well
as the median program results in CSE Measurement Study. It allows to highlight limitations
induced in performance assessment by the variability of the reference itself, and
to state that the median program is at least as close to the “Gold Standard” as the
median of the referees.
