In the current study, different correction methods generally corrected for heart rate changes the same way with placebo and drug, with the exception of the linear population-based method, QTcPL, which more effectively removed the heart rate dependence on exenatide than on placebo (Table 1).
Current methods include QT intervals corrected for heart rate (HR).
B. The left ventricular ejection time (or flow-time) corrected for heart rate provides an index of preload (hypovolemia).
Objective: To examine the effects of halothane, isoflurane, and sevoflurane on Q-Tc interval (corrected for heart rate) during inhalation induction of anesthesia.
Objectives: To evaluate whether QT interval, QT interval corrected for heart rate (QTc), and QTc dispersion changes are already present in children and adolescents with diabetes.
Objective: To determine if increased QT interval dispersion (corrected and not corrected for heart rate) is associated with perioperative silent myocardial ischemia or postoperative adverse cardiovascular events.
QT dispersion was significantly greater in AN than in the thin and control groups (QT dispersion: 50 ± 14 vs 34 ± 9 and 37 ± 11 ms, P <.001; QT interval dispersion corrected for heart rate: 49+12 vs 34 ± 9 and 36 ± 7 ms, P <.01, respectively).
All pertinent physiologic parameters were corrected for heart rate.
QTc (QT interval corrected for heart rate) was corrected for heart rate by using the Bazett formula [ 25].
QT interval was corrected for heart rate using the Bazett formula (Bazett 1920).
The QT intervals were corrected for heart rate (HR) (QTc) using Bazett's formula.
