Brugada Syndrome - ECG

Brugada syndrome is a rare inherited defect that can cause a certain ECG changes that may be found in a young patient. The problem is caused by a mutation of an ion canal in myocardial cells. It can have more ECG manifestations; there are usually mentioned three main types. Some of them are very hard to diagnose even for a skilled cardiologist and therefore I will mention at least the most obvious type. The maximal changes are located in chest leads V1-V3 where we find a bizarre rSr' pattern with a saddle-shaped elevated ST segment and a negative T wave. 

 

Brugada Syndrome - ECGBrugada syndrome – rSr' pattern with a saddle-shaped elevated ST segment and a negative T wave is seen in lead V1 and V2.
 

Conclusion: Such finding is a very serious in a patient with a recent episode of unconsciousness. The suspicion of Brugada syndrome must be confirmed or excluded by a cardiologist and eventually further examined in a specialized cardiologic department. If the syndrome is confirmed, implantation of ICD is usually indicated as there is a higher risk of sudden death due to an episode of ventricular fibrillation.
