LOINC short name : Q-T interval corrected Fridericia;
LOINC description : The purpose of calculating a corrected QT interval (QTc) is to normalize each individual
QT measurement from a given study to a single measurement that would represent the
QT interval if the patient had a heart rate of 60 beats per minute. Several formulas
are available to calculate QTc, including the Bazett formula and the Fridericia formula.
Bazett's formula is used most commonly, but for situations in which the patient's
heart rate is significantly elevated, the Fridericia formula may yield a more accurate
QTc that reflects the QTc that would have been obtained were the patient in normal
sinus rhythm. [PMID: 23972343] To report a QTc without specifying a method, use LOINC
code 8636-3 QT interval corrected. To report QTc calculated using the Bazett formula,
use LOINC code 76635-2.;
