Correct a measured QT interval for heart rate using Bazett’s equation.
| Input | What it means |
|---|---|
| Heart rate/pulse | Use the observed finding or laboratory value for this criterion, following the definition shown in the form. |
| QT interval | Use the observed finding or laboratory value for this criterion, following the definition shown in the form. |
At 60 bpm, RR=1 second, so a QT of 400 ms gives QTc=400 ms.
