The JT Interval and Pro-Arrhythmic Risk Measured from the J-point to the end of the T-wave, the JT interval represents the time for ventricular repolarization in the setting of ventricular conduction abnormalities. JTc=QTc-QRS When do you use the JT Interval? - Right Bundle Branch Block - Left Bundle Branch Block - Ventricular Pacing Prolonged JT interval was a stronger risk factor for mortality than prolonged QT interval in patients with QRS ≥120 ms Rachel Klosko, PharmD @rachel_klosko #JT #Interval #JTInterval #QTc #electrocardiogram #pathophysiology #ekg #ecg #cardiology
