About the QTcF Calculator (Fridericia's Formula)

This QTcF calculator is a clinical tool that helps healthcare providers determine the corrected QT interval using Fridericia’s formula. It is particularly useful in TB management when QT prolongation is a concern due to medications like bedaquiline or clofazimine.

By entering the patient’s QT interval (in milliseconds) and heart rate (in bpm), this tool instantly provides the QTcF value, aiding safe treatment decisions and ongoing ECG monitoring. It is suitable for both adult and pediatric TB patients.
