Having an AED in the home is a good idea considering Sudden Cardiac Arrest (SCA) is a leading cause of death in the US, killing an estimated 325,000 Americans each year. SCA kills on average 1,000 people every day. Thatís one person every two minutes. Without emergency medical help, SCA leads to death within minutes. Victims of cardiac arrest can be saved if an AED is available to deliver an electric shock and restore the heart to its normal patterned rhythm.
