represents the type (for example: V means ventricular premature beat, S means atrial premature
beat), the percentage means what percentage this kind is in the total. No percentage means no
wave.
V: ventricular premature beat module
S: supra premature beat module
Af: atrial fibrillation module
VF: ventricular flutter module
Vf: ventricular fibrillation module
The top right window is display window for the selected template in the template cluster, which
displays every waveform.
The bottom right window is the waveform show window, which displays the detailed
