QT Calculator lets you take a picture of anyECG, and with a few taps on your screen, calculates the QTinterval, QTc, and RR of your ECG. You can also chose betweenBazett’s, Fredericia’s, Framingham, and Hodges formula for the mostaccurate corrections. This app makes it easy to analyze the QT fromyour ECG without having to count tiny squares all day long.

Feel free to contact me about ideas for the app. Enjoy!
