The wideband signal is shown in the upper panel and a filtered signal in the lower panel (third order Butterworth bandpass filter with cutoff frequency of 5–50Hz). One second of data is shown. Following an isopotential period, a QRS cardiac wave form can be seen (cardiac depolarization) followed by a T-wave (cardiac repolarization).
