ECG Caliper funktioniert nicht

This application allows you to measure intervals in ECGs that you capture with the camera, or import from the Photo Library.  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.  ECGs are recorded with a paper speed of 25 mm per second.  Intervals such as PR, RR or QTc can be easily measured, at any level of zoom.  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.
