Computes corrected QT using Bazett's, Fridericia's or Sagie's formula.
compute_qtc(qt, rr, method)
QT interval in msec
QT interval
A numeric vector is expected. It is expected that QT is measured in msec.
RR interval
A numeric vector is expected. It is expected that RR is measured in msec.
Method used to QT correction
Permitted Values: "Bazett", "Fridericia", "Sagie"
"Bazett"
"Fridericia"
"Sagie"
Depending on the chosen method one of the following formulae is used.
method
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 %>%.
