I would really love to find out if I need to invert the waveform when using the hand to chest lead. Lead V mine looks to hav extremely deep and peaked waveforms and I want to make sure I’m reading correctly. Does anyone at the company checking these questions???
I am definitely not an expert on these issues, but I do the hand to chest method, with the device contacting my chest under my left nipple. The wave form seems to be the same type as when I do hand to hand; but with hand to chest, I see clearer, bigger waves with fewer irregularities and less noise.
P.S. I think you get a different wave form if you put the device against other parts of your chest. I have not tried to figure that out. I just stay with the contact point under my left nipple, as I mentioned in a message a few minutes ago.
