JTc Interval Calculator
JTc Interval: Explanation and Clinical Context The JTc interval represents the corrected JT interval, calculated as the QT interval minus QRS duration, adjusted for heart rate. It isolates ventricular repolarization from depolarization, offering a more precise assessment than QTc in patients with wide QRS complexes. Normal values are generally <330 ms for men and <340 ms for women. Prolonged JTc is associated with an
