Sudden arrhythmia death syndromes (SADS) are genetic heart rhythm abnormalities conditions that can cause sudden death in young, apparently healthy people, who may be undiagnosed. These conditions can be treated and deaths can be prevented. Warning Signs: family history of unexpected, unexplained sudden death under age 40; fainting or seizure during exercise, excitement or upon sudden shock or surprise; consistent or unusual chest pain and/or shortness of breath during exercise.
SADS conditions are passed down from parent to child with each child of an affected parent having a 50% chance of inheriting the condition. It is estimated that over half of the 4000 SADS deaths each year of children, teens, or young adults had one of the top two warning signs: 1) family history of a SADS diagnosis or sudden unexplained death (usually undiagnosed and untreated) of a family member, or 2) fainting.
