compute_qtc {admiral} | R Documentation |
Computes corrected QT using Bazett's, Fridericia's or Sagie's formula.
compute_qtc(qt, rr, method)
qt |
QT interval A numeric vector is expected. It is expected that QT is measured in msec. |
rr |
RR interval A numeric vector is expected. It is expected that RR is measured in msec. |
method |
Method used to QT correction Permitted Values: |
Depending on the chosen method
one of the following formulae is used.
Bazett:
\frac{QT}{\sqrt{\frac{RR}{1000}}}
Fridericia:
\frac{QT}{\sqrt[3]{\frac{RR}{1000}}}
Sagie:
1000\left(\frac{QT}{1000} + 0.154\left(1 - \frac{RR}{1000}\right)\right)
Usually this computation function can not be used with %>%
.
