ECG Caliper 4.0

This application offers a practical approach to measuring intervals in electrocardiograms (ECGs) captured through the camera or imported from the Photo Library. It facilitates the measurement of essential intervals such as PR, RR, and QTc with ease, even at various zoom levels.

Features:

• Utilizes iOS Document Scanning support to scan ECGs directly into the app.
• Allows measurement of intervals at any zoom level once calibrated.
• Enables straightforward calculation of QTc, PR, and RR intervals.
• Includes an overlay grid for assessing rhythm regularity and identifying repeating patterns.
• Automatically copies calculated intervals to the clipboard for convenient export.

How it works:

The application relies on a standard paper speed of 25 mm per second for ECG recordings. This allows for the translation of distance on-screen between two points into a duration post-calibration. The app displays the distance between two points in milliseconds (ms), which can subsequently be recorded. The QTc interval can be calculated using the Bazett formula.
