There are two types of ST elevation: (1) the type I pattern has ST elevation that is convex upward, terminating in a negative T wave; this is the most sensitive and specific pattern; (2) the type II pattern has ST elevation that is concave upward (saddleback pattern) and is less sensitive and less specific. +++ Pearls ++ Brugada syndrome is thought to be a sodium channelopathy. Patients with Brugada syndrome are at risk for spontaneous arrhythmias and sudden cardiac death. ECG changes in Brugada syndrome patients are transient and often unmasked by fever, ischemia, and sodium channel–blocking drugs. Consultation with a cardiologist is recommended for electrophysiologic testing and automated implantable defibrillator placement. ++ FIGURE 23.43A Brugada Syndrome. (ECG contributors: Clifford L.
