QTc Bazett
Correct the QT interval for heart rate with the Bazett formula.
Description
Correct the QT interval for heart rate with the Bazett formula.
QTc Bazett is a focused biology tool that correct the QT interval for heart rate with the Bazett formula. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use QTc Bazett
Use QTc Bazett when you need to correct the QT interval for heart rate with the Bazett formula. Enter QT interval and RR interval using the definitions and units below so the result can be reproduced.
- QT interval
- A finite measured or assumed value greater than or equal to 5e-324, expressed in ms.
- RR interval
- A finite measured or assumed value greater than or equal to 5e-324, expressed in s.
How QTc Bazett calculates the result
The published tool contract uses this rule: Correct the QT interval for heart rate with the Bazett formula.1
- Corrected QT interval
- The calculated corrected qt interval in ms.
Limitations of QTc Bazett
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original QT interval and RR interval values and their units alongside the result. QTc Fridericia is useful when you instead need to correct the QT interval for heart rate with the Fridericia formula. RPP provides another view by helping you compute the rate pressure product from heart rate and systolic pressure.
