I'm running the Lochness Marathon to fundraise (for the very last time I promise) to help buy a defibrillator for St Peter's (CofE) Primary School in Brotton. I hope and pray it will never be used but if ever it is I reckon it's worth 26.2miles of anyone's legs. If you think you can help reach the target I'd love your help.xxx According to official government statistics, as many as 12 young people die each week as a result of sudden cardiac arrest (SCA). Of those, 80% show no prior symptoms. SCA is when the heart's normal rhythm suddenly becomes chaotic. The heart can no longer pump the blood effectively and the victim collapses, stops breathing, becomes unresponsive, and has no detectable pulse. In addition to heart problems, SCA can also be triggered by: asphyxiationelectrocutionchest impact or traumaThe only proven treatment to restore a normal heart rhythm after an SCA is defibrillation with an automated external defibrillator (AED).
