ECG Rhythm App: Corrected QT

The ECG Rhythm App: Corrected QT is a user-friendly tool designed for health professionals to precisely calculate the corrected QT interval (QTc) from electrocardiogram (ECG) readings. This app incorporates three well-known correction formulas—Bazzet, Fredericia, and Framingham—to adjust the QT interval according to heart rate variations, providing an accurate estimate at 60 beats per minute.

Ideal for assessing ventricular depolarization and repolarization, this app helps identify prolonged QTc intervals linked to risks such as ventricular arrhythmias and Torsades de Pointes. Simply input the QT interval in milliseconds and heart rate in beats per minute to get reliable QTc values. The app is completely free and strives to support clinical judgment, although users are advised to consult experts and verify results before making clinical decisions.
