After collapsing mid-game and losing her pulse, a 17-year-old soccer player required an AED. At the hospital she was found to have long QT syndrome on ECG. In this Medmastery lesson, learn to recognize long QT on ECG by reviewing rhythm, rate, and axis, then calculating the corrected QT interval (QTc) with Bazett's formula in a pediatric patient.
