#' Fifth annotated beat (lead MLII) from patient sel100 in 'QT database'
#'
#' 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.
