Utilize our ECG QTc Interval Calculator to accurately determine the Corrected QT (QTc) interval. This crucial metric helps assess cardiac repolarization, identifying potential risks like long QT syndrome and guiding clinical decisions based on your measured QT interval and heart rate.
Formula:
The Corrected QT (QTc) interval is typically calculated using Bazett's formula, which adjusts the QT interval for heart rate:
QTc = QT / √(RR Interval in seconds)
- QTc: Corrected QT Interval (in milliseconds, ms)
- QT: Measured QT Interval (in milliseconds, ms)
- RR Interval (seconds): The time between two consecutive R waves, calculated as 60 divided by the Heart Rate (BPM).
By providing your measured QT interval and heart rate, this tool determines your QTc value, offering a rate-corrected measure of ventricular repolarization.
