Voltage electric activity data (mV) of the fifth annotated heartbeat for patient sel100 in 'QT database'. 200 samples were collected along 0.8 seconds with a sampling frequency of 250 Hz. Data records correspond to samples from 151248 to 151049 and can be dowload as text files from 'Physionet' website. Annotated beats were manually revised by experts including R peaks and fiducial marks.
A numeric vector.
