Answer: Choice 2: Brugada Type 2
Explanation:
Type I: Lead V1 has a “coved” ST segment elevation of at least 2 millimeters, followed by a negative T wave.
Type II: There is a “saddleback” appearance of the ST segment in lead V1 with ST segment elevation of at least 2 millimeters; this can be present in normal individuals as well.
Type III: Features of type I (coved) or type II (saddleback) with < 2 mm of ST segment elevation.
These ECG changes can be provoked in the electrophysiology lab by infusing procainamide.
The treatment for Brugada Syndrome is an ICD (implantable cardioverter defibrillator).
