EKG Inverted unless I hold it inverted

If I hold it in my hands like the picture, my P Wave goes down. So of course when I hold the device upside down I see what I expect to see.

Anyone else have this issue and know why?

Here’s what I expect to see.

Same here. It’d be great if someone could say something about this…

You can invert the image by selecting the three dots in the upper right corner and choosing invert. Unfortunately this only works on the waveform you are viewing and reverts when you exit.
