About EP QTc

This app collects over 30 published formulas for calculating the corrected and predicted QT interval (QTc and QTp). Included are details on each formula and reference links. Results are analyzed statistically and graphed. Published definitions of normal and abnormal QTc intervals are also included. This is no ordinary calculator that just gives you the results of Bazett's formula. If you are interested in this fascinating corner of electrocardiology, this app is for you.

What’s new

Version 1.10.0 · Updated February 11, 2026

Allow the choice of only one set of QT limits at a time. Although the previous system could allow choosing criteria for both long and short QT intervals at the same time, some combinations of criteria made no real sense, so this version doesn't allow multiple criteria at the same time. Fix some layout problems. Update icon.
