Transient J-Wave Appearance in the Inferior-Lateral Leads during Electrical Storm in a Patient with Brugada Syndrome

A 67-year-old male patient was admitted with an abrupt sudden cardiac death. He represented with an extreme electrical storm of 30 times of ventricular fibrillation (VF) episodes on one day. External shocks were performed to terminate VF. Transient J-wave in the inferior-lateral leads and Brugada electrocardiography pattern on the right precordial leads appeared during the electrical storm. And J-wave disappeared after the termination of electrical storm. We report a case of the appearance of J-wave during electrical storm in a patient with Brugada syndrome.
