signals
Sample EEG and ECG data.
signals
A data.frame containing 10 seconds of data
electrophysiological data, sampled at 256 Hz with a 24 bit A/D converter,
measured in microVolts. The data frame consists of 2 columns (channels):
electroencephalogram (EEG) data measured from electrode Pz according to the 10-20 system, referred to algebraically linked mastoids (the brain's alpha rhythm is clearly visible).
electrocardiogram (ECG) data, recorded bipolarly with a V6 versus V1 chest lead (this lead maximizes the R wave of the ECG with respect to the P, Q, S, T and U waves of the cardiac cycle).
