摘要： An automatic method of measuring parameters of multi-channel cardiac electrogram signals including at least one ventricular channel and at least two other cardiac channels, the method comprising: (a) digitizing and filtering a ventricular-channel signal and a first other cardiac signal over a first preset time window to generate corresponding absolute-value velocity signals; (b) estimating a pulse interval in the ventricular absolute-value velocity signal; (c) autocorrelating the first other cardiac absolute-value velocity signal; (d) selecting a peak value of the autocorrelation based on ventricular pulse-interval estimates; and (e) setting the cycle length of the first other cardiac signal to the lag value of the selected peak in the autocorrelation. Local activation times are measured, and several multiple-channel configurations decrease measurement time, decrease the impact of signal degradation, and increase the amount of data generated during a procedure.
