SADS
Sudden Arrhythmia Death Syndromes
Sudden Arrhythmia Death Syndromes are genetic heart conditions that can cause sudden death in young, healthy people.
Warning signs:
- Family history of unexplained sudden death under the age of 40.
- Fainting or seizure during exercise, excitement, or stress.
- Consistent or unusual chest pain or shortness of breath during exercise, excitement, or stress.
SADS conditions are:
- Brugada Syndrome
- Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)
- Long QT Syndrome (LQTS)
- Short QT Syndrome (SQTS)
- Timothy Syndrome
- Wolff Parkinson White (WPW)
Other SADS related conditions may include malformations of the heart muscle. A dysplasia (misplaced) or cardiomyopathy (thickening) of the heart muscle can be related to Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C), hypertrophic cardiomyopathy (HCM), or Dilated Cardiomyopathy (DM). These conditions can also cause sudden cardiac arrest in the young.
