This application allows you to measure intervals in ECGs that you capture with the camera, or import from the Photo Library. Intervals such as PR, RR or QTc can be easily measured, at any level of zoom.

• Scan ECG directly into the app with iOS Document Scanning support
• Once calibrated, intervals can be measured at any level of zoom
• QTc can be easily calculated, as well as PR and RR intervals
• A grid can be overlaid on top to check for regularity of rythm, or repeating patterns
• Once calculated, intervals are automatically copied to the clipboard for easy export

How it works:
ECGs are recorded with a paper speed of 25 mm per second. That means that the distance on screen between 2 points can be translated into a duration, once calibration is achieved. 
The distance between two points in the ECG will then be displayed in millisecond (ms) and can be recorded. QTc can be computed using the Bazett formula.

No medical decision regarding diagnosis or treatment should be taken on the basis of results provided by this app without seeking professional medical advice.
