(a) Section of 10 s of raw ECG from a measurement lasting 1800 s. (b) The heart rate determined from the ECG was averaged with respect to the onset of the finger movement task performed by the subject. The changes in the averaged heart rate are within a range of 4 beats/min. This is small in relation to the 63 beats/min mean value and it can be concluded that the subject was relaxed.
