QTc

In electrocardiography, the duration of the QT interval adjusted for the patient's heart rate. Prolonged QTc's are associated with an increased risk of ventricular dysrhythmia and sudden death.

The followings were identified as useful indices for predicting and estimating the occurrence of a fatal arrhythmia: the interval between the peak and the end of T wave (Tp-Te),[2] the ratio of the Tp-Te interval to the QT interval ([Tp-Te/QT][3]), and the JT interval (JT), which is measured from the end of the QRS complex to Te.[4] The QT interval may be affected by sex and age.[5] However, little is known about the co-effect of the inhaled agent and sex on the corrected QT (QTc) and Tp-Te/QT and Tp-Te/JT ratios.
