### 2/5 — Lacking complete ECG normal values

*2016-09-06*

I was excited to download this app, mainly for the ECG normal values (I use my own institution's echo Z scores). However I was disappointed to see that normal values for R and S voltages are not included in this app. These values are just as important as other intervals/axis and much harder to remember. The app becomes useless if I need to go to another source for every single ECG anyways... This absolutely needs to be updated!

### 3/5 — Boston?

Why is there no ability to calculate Boston z-scores?

### 5/5 — Really useful
