EKGraph with SonoHealth is very convenient and for most things and I like it very much. However, I have a unit that I bought from another company most of a decade ago. It’s old and inconvenient BUT it produces significantly more detailed and accurate wave forms. With SonoHealth, the little P waves tend to get lost in the noise. (I use it with one hand and chest.) My best guess is that the older unit’s advantage comes from the fact that it relies on traditional pads that stick to your chest and arm. It would be nice if this were a SonoHealth option for the times when you really want to see the details of the wave form. I suspect it’s uncommon enough that you wouldn’t want to include pads and wires with the product, but a place to attach them and some guidelines would be useful enough.
