Description
This is a tool for people reading EKGs. Simply hold the edge of your phone to an ekg, then use the touchscreen to adjust caliper width. You can customize caliper size and estimate heart rate after a one-time calibration.Real calipers cost $4-$10. This is a great substitute if you don't own a pair and need a quick fix!

Works ok. Calibration and r to r measurements are off a bit. Would like to be able to adjust for sweep speed and measur pr qrs and qtc as well as amp

Does it's job. Wish it could measure PR and QRS intervals.

Pretty simple but useful for quick rate and rhythm determination. The calibration says to set it to 1 cm but setting it to 2 large boxes works best.
