Overview
Brugada syndrome usually becomes apparent in adulthood, although signs and symptoms, including sudden death, can occur any time from early infancy to old age. The mean age of sudden death is approximately 40 years. This condition may explain some cases of sudden infant death syndrome (SIDS), which is a major cause of death in babies younger than one year. It is characterized by sudden and unexplained death, usually during sleep. Sudden unexplained nocturnal death syndrome (SUNDS) is a condition characterized by unexpected cardiac arrest in young adults, usually at night during sleep. This condition was originally described in Southeast Asian populations, where it is a major cause of death. Researchers have determined that SUNDS and Brugada syndrome are the same disorder.
Complications
The following arrhythmias may occur in the patient with Brugada syndrome:
- Polymorphic VT resembling a rapid Torsade de Pointes (TdP)
- Monomorphic VT is observed infrequently
- VT/VF often terminates spontaneously in patients with the Brugada syndrome which may explain why patients wake up at night after episodes of agonal respiration caused by the arrhythmia.
