Help Save Lives. The sudden death of a child, young person or healthy adult is traumatic and devastating. This is why SADS UK donates cardiac equipment to save lives. The charity donates heart monitors to identify abnormal heart rhythms and defibrillators to restart the heart if a person suffers a cardiac arrest. The charity is encouraged by the lives that have been saved by using this equipment. SADS UK supports research into Sudden Arrhythmic Death Syndrome and supports people living with cardiac conditions.
