What is the characteristic EKG morphology for Type 1 Brugada syndrome?

Type 1 Brugada syndrome is characterized by a specific EKG morphology referred to as the "type 1 Brugada pattern." This pattern presents as a right bundle branch block (RBBB) configuration in leads V1 and V2. The most defining characteristic of this type is the descending ST segment that forms a coved shape, which is often followed by a negative T wave. This distinctive morphology is crucial for identifying patients who may be at risk for life-threatening arrhythmias associated with Brugada syndrome.

In clinical practice, recognizing this unique EKG pattern is essential because it differentiates Brugada syndrome from other causes of ST elevation. The coved shape and the inverted T wave provide insight into the underlying pathophysiology of the condition, which involves alterations in cardiac repolarization due to ion channel dysfunction. Understanding these characteristics aids in the diagnosis and management of patients who may be experiencing arrhythmias related to the syndrome.
