Sudden sleep death

J-wave syndrome is the culprit of sudden sleep death, and J-wave is intrinsically related to sudden death. J-wave syndrome is a general term for a variety of clinical syndromes related to J-wave, including premature repolarization syndrome, unexpected sudden death syndrome, Brugada syndrome, and idiopathic ventricular fibrillation. Brugada syndrome is a primary ECG disease caused by abnormal ion channel genes. It belongs to a high-risk group of sudden cardiac death and has a severe prognosis. The disease was first proposed by the Spanish scholars Brugada P and Brugada J in 1992. In 1996, Japan's Miyazaki et al. Named the disease Brugada syndrome. Brugada syndrome is more common in men. Brugada syndrome needs to be identified in clinical work in time to intervene early. Patients without symptoms, such as ECG, are also normal, and can be used for induction tests or electrophysiological examinations to confirm the diagnosis. Immediate ICD implantation once the diagnosis is established is the only effective way to prevent sudden death in patients.
