compute_qtc: Compute Corrected QT

In epijim/admiral: ADaM in R Asset Library

Description

Computes corrected QT using Bazett's, Fridericia's or Sagie's formula.

Usage

compute_qtc(qt, rr, method)

Arguments

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: "Bazett", "Fridericia", "Sagie"

Details

Depending on the chosen method one of the following formulae is used.

Bazett:

QT/√(RR/1000)

Fridericia:

QT/(RR/1000)^(1/3)

Sagie:

1000(QT/1000 + 0.154(1 - RR/1000))

Value

QT interval in msec
