[Dynamic ECG changes as a result of Brugada syndrome, an overlooked diagnosis?]

Brugada syndrome is a primary electrical disease involving a wide spectrum of phenotypes. The hallmark of Brugada syndrome is the ST elevation in leads V1 to V3. We present three cases of Brugada syndrome. The first patient was diagnosed via routine ECG and a programmed electric stimulation. The second patient was mistakenly diagnosed as having a right coronary occlusion. The last patient had been resuscitated before admittance and received an implantable cardioverter-defibrillator. Treatment of patients with Brugada syndrome is limited by the lack of reliable indicators of risk.
