### Which QT Correction Formulae to Use for QT Monitoring qtc calculator

The QT interval is a measure of the duration of ventricular repolarization. It approximates the time interval between the start of depolarization and the end of repolarization of the ventricular myocardium.1 QT prolongation is associated with a risk for cardiac arrhythmias given that it can result in early after depolarizations, provoke Torsades des Pointes, and lead to ventricular fibrillation, causing sudden cardiac death.2 The risk assessment for QT prolongation of inhospital patients is based on their medication prSee more on ahajournals.org**Cited by:** 166**Publish Year:** 2016**Author:** Bert Vandenberk, Eline Vandael, Tomas Robyns, Joris Vandenberghe, Christophe Garweg, Veerle Foulon, qtc calculatorWhat is a normal QTc calculation Bazett?To overcome this calculated QT (QTc) is calculated by using a formula.
