Note: a new version, called EP Calipers 3, is now on the Microsoft Store. It is has an updated user interface for Windows 10 and 11. Please consider using this new version.
EP Calipers provides electronic calipers for measuring intervals on images of electrocardiograms (ECGs) or electrophysiologic recordings. In the electrophysiology lab electronic calipers are included as part of the recording system. EP Calipers provides similar electronic calipers for use on your Windows computer. The electronic calipers of EP Calipers are more accurate, easier to use, and less dangerous than mechanical calipers (no sharp points!). EP Calipers can open and analyze ECGs stored as image files (e.g. JPG or PNG) as well as PDF format, including AliveCor™ mobile ECG recordings. Transparent windows can be used to make measurements on images on your desktop or in a web browser.
