This is a critically important determination because of the 2017 AHA/ACC/HRS Guidelines for Management of Patients with Ventricular Arrhythmias and the Prevention of Sudden Cardiac Death. Frick's presentation in today's case is its simplicity in conveying a critically important finding affecting the outcome of this patient.

Brugada syndrome is thought to account for about one fourth of sudden cardiac deaths in individuals with structurally normal heart. Even though mutations in other channels have been described in Brugada syndrome, only those in SCN5A gene are considered to be definitely disease causing. mV or R/q ≥ 0.75.
