Definition of the nine waveforms.

Waveform	Definition
Up-P	Waveform from the start of the P wave to the peak of the P wave
Down-P	Waveform from the peak of the P wave to the end of the P wave
PR	Waveform from the end of the P wave to the start of the QRS wave
Up-R	Waveform from the start of the QRS wave to the peak of the R wave
Down-R	Waveform from the peak of the R wave to the end of the QRS wave
ST	Waveform from the end of the QRS wave to the start of the T wave
Up-T	Waveform from the start of the T wave to the peak of the T wave
Down-T	Waveform from the peak of the T wave to the end of the T wave
TP	Waveform from the end of the T wave of the current beat to the start of the P wave of the next beat
