Table 5 Formulae for the calculation of the corrected QT interval [80]
From: Assessment and management of cardiovascular complications in eating disorders
Bazett formula for corrected QT interval | Friderica formula for corrected QT interval |
|---|---|
\(QTcB = \frac{{QT\;{\text{int}} erval\;in\;\sec onds}}{{\sqrt {Cardiac\;cycle\;in\;\sec onds} }} = \frac{QT}{{\sqrt {RR} }}\) | \({\text{QTcF}} = \frac{{{\text{QT}}\;{\text{ interval}}\;{\text{ in}}\; {\text{seconds}}}}{{\sqrt[3]{{{\text{Cardiac}}\;{\text{ cycle}}\;{\text{ in}}\;{\text{ seconds}}}}}} = \frac{{{\text{QT}}}}{{{{{\text{RR}}}}}}\) |
