Sudden cardiac arrest (SCA) is an ‘electrical’ problem.  Sudden cardiac arrest occurs when the heart malfunctions and suddenly and unexpectedly stops beating normally. If this happens, blood stops flowing to the brain and other vital organs. This results in the victim becoming unresponsive and not breathing or not breathing normally (gasping).  If it’s not treated, sudden cardiac arrest usually causes death within minutes.

Every minute counts.

With sudden cardiac arrest (SCA), every minute without CPR and defibrillation reduces the chance of survival by 7-10 per cent. The shorter the time to defibrillation, the better the chance of survival. If a victim receives a shock within one minute, there is a 90% chance of survival. If a victim waits 10 minutes for a shock, the chance of survival drops to less than 5%.


Cardiac Science was founded in 1991, and has quickly become a leader in developing and marketing potentially life-saving AED technology. The company has continually brought innovation to the AED category, and has achieved more than 100 patents in pursuit of its primary goal: to contribute to saving more lives by delivering the highest quality AEDs available.

From Rescue Ready® technology that self-tests Powerheart® AEDs every day and helps ensure readiness, to STAR® Biphasic technology that customises defibrillation energy to the patient,
Powerheart AEDs incorporate technology that ensure they are easy to use and ready to rescue. It’s a legacy of innovation that goes back to the company’s early days, when Cardiac Science developed the first FDA-cleared fully automatic defibrillator.
