QTcF Calculator

QTcF Calculator calculator can be used to correct the QT interval for heart rate differences using the Bazett formula.

Input Parameters

Calculation Results

Calculation Formula

QTcF = QT / √RR interval

Where:
QTcF is the corrected QT interval on a fixed heart rate.
QT is the QT interval measured in seconds.
RR interval is derived from the heart rate (RR = 60 / heart rate).

Result

QTcF: -- seconds

How to Use the QTcF Calculator

The QTcF calculator is used to correct the QT interval for differences in heart rate. This is important because a longer QT interval can indicate a higher risk of arrhythmias. To use the calculator:

  1. Enter the QT interval in seconds.
  2. Enter the heart rate in beats per minute (bpm).
  3. Click the "Calculate" button.
  4. The corrected QT interval (QTcF) will be displayed in seconds.

Understanding the Formula

The Bazett formula is used to correct the QT interval:

QTcF = QT / √RR interval

Where QT is the QT interval and RR interval is calculated as 60 divided by the heart rate.

Interpreting the Results

A corrected QT interval (QTcF) that is prolonged may indicate an increased risk of arrhythmias. It is important to consult with a healthcare professional for interpretation and management of QT interval prolongation.
