Recording the cardiac interbeat interval distribution.
A compact device is described, which picks up the R wave of the ECG, calculates the duration of successive interbeat intervals, classifies them in eight classes and stores the receptive counts in an integrated-circuit register. The distribution of intervals counted over the experimental period is retrieved through a separate numerical readout device.
