Great for quick ECG measurements.
Would recommend, fits in pocket or pen holder. Wish it was a little thicker, but would buy again

Fast EKG calculator
Good quality, great information. These fit nicely in my scrub pants along with other reference materials. Don’t need those calipers! Helps to use these at work once in awhile as when you take tests on EKGs, you don’t have the luxury of the data on the test print you are looking at. Probably wouldn’t be allowed to use this tool, but by having it handy and using once in awhile you won’t forget all those numbers and quick calculation information when it is just you and a calculator and maybe calipers.

Handy EKG ruler
This is perfect to keep in my pocket at work! I am still learning g how to read EKG strips and this is just the cheat sheet I need when we have to interpret our tele strips on the weekends.

Expensive but worth it. I have this in my scrub pocket every day. A mini lifesaver

I don’t know why it’s measured in cm instead of mm
