  1. Prevention of Sudden Cardiac Death Ali Shakir, MD Medical Director, Electrophysiology Services Henry Ford Macomb Hospital September 17th, 2011

  2. Objectives • What is Sudden Cardiac Death (SCD)? • Background • Heart Function • AED

  3. Normal Heart Beat

  4. Sudden Cardiac DeathDefinition The term sudden cardiac death refers to natural death from cardiac causes, heralded by abrupt loss of consciousness within one hour of the onset of acute symptoms A sudden, unexpected loss of heart function. The term "death" is somewhat misleading because some people survive Typically resulting from a sudden change in the rhythm of the heart

  5. Sudden Cardiac Arrest Facts SCA claims an estimated 325,000 lives each year 1,000 lives every day, one life every two minutes SCA accounts for half of all cardiac-related deaths Over half of SCA victims have no prior symptoms Survival requires emergency medical intervention and defibrillation within the first few minutes following arrest The survival rate is as high as 90 percent if treatment is initiated within the first few minutes following arrest 1Heart Rhythm Society. “Sudden Cardiac Arrest Facts”. 2008. HRS Online Feb 2009

  6. Epidemiology More people die from sudden cardiac arrest than from AIDS, breast cancer, and lung cancer combined 1 1Heart Rhythm Society. “Sudden Cardiac Arrest Facts”. 2008. HRS Online Feb 2009

  7. Know Your Ejection Fraction • The ejection fraction is an estimate of the amount of blood pumped out of the heart chambers every beat • Normal is > 55% • Increased risk for sudden cardiac death are those with ejection fraction < 35%

  8. A  man was riding his Harley along a Michigan highway when suddenly the sky clouded above  his head and, in a booming voice, God  said, 'Because you have TRIED to be  faithful to me in all ways, I will grant you  one wish.' The biker pulled over and  said, 'Build a bridge to Hawaii so I can Ride over anytime I want.

  9. God said, 'That  request is materialistic, think of the  enormous challenges for that kind of  undertaking; the supports required to  reachthe bottom of the Pacific and the  concrete and steel it would take! It will  nearly exhaust several natural resources. I  can do it, but it is hard for me to justify your  desire for worldly things.Take a little more  time and think of something that could possibly  help mankind.'The biker thought about it for  a long time.

  10. Finally, he said, 'Okay,  I wish that I, and all men, could  understandour wives; I want to know how she  feels inside, what she's thinkingwhen she  gives me the silent treatment, why she cries,  what shemeans when she says 'nothing's  wrong', and how I can make a woman truly  happy.

  11. And  God replied, 'You want two lanes or four  lanes on that bridge?'  

  12. Automated External Defibrillator (AED) • AED is a portable electronic device which automatically diagnoses cardiac arrhythmias and treats through defibrillation (shock to the heart)

  13. Time is Critical • For every minute that a person in cardiac arrest goes without being resuscitated, the chance of survival decreases by 7 percent per minute • After/while calling 911, AED can provide life saving capabilities

  14. AED • Designed to be used by non health care professionals • Majority of units have spoken prompts to instruct the user • Can be found in public areas • Often brightly colored and found near entrance

  15. AED • AED will instruct the user to connect the pads to the bare chest of the patient • After connected, everyone should avoid touching the patient as this can interfere with detection of the heart rhythm • If dangerous rhythm is found, it will automatically deliver a shock

  16. Future Directions Teach Basic Life Support and Advanced Life Support Classes for those who are interested Increase availability of AEDs in public places Educate more individuals regarding use of

  17. CONCLUSIONS • Know your ejection fraction (Heart Function) • Know where AEDs are located and understand basic function • Great tool for saving lives
