Title : A low-cost, automatic, external defibrillator and pacemaker for home/office to prevent sudden cardiac death


S udden cardiac death(SCD)-caused by ventricular fibrillation(VF) or standstill- occurs in  about  1000 persons/day in US alone. Since survival drops by 10% for every minute delay- no ambulance in the world will be quick enough to save them. The existing AEDs, that are now distributed in public places are not a good solution for home-use, due to their high cost for battery and capacitor not needed in TED. AICDs inserted surgically-are very expesive and risky and help only in few patients. Our TED device modifies by computer the sinusoidal alternating electrical current from the mains to a biphasic defibrillatory wave and its cost-affordable to every household. In addition -it can pace the heart in case bradycardia or  standstill caused SCD or it occurred after the electric shock.. In order to prove the safety and feasibility of TED -we performed 2 animal experiments: in the first-we used 5 pigs:repeated defibrillation of stable VF after 15 seconds was applied by TED or by a standard AED. Defibrillation was successful by both devices and thresholds were found to be similar. The second experiment used a rat model: six rats, underwent a mid LAD coronary closure and 3 months later VF was induced and TED defibrillation and external pacing was successfully achieved using TED in all ,at a heart rate above their rate, for an unlimited time before and after defibrillation. We conclude that modified alternating shock delivered by our device-TED- is feasible and as effective as that of the standard AED. This low-cost new technology should be used to prevent sudden cardiac arrest occurring at home/office.

Audience Take Away:

• The audience will become aware of the biggest unmet meet in medicine:the huge toll of sudden cardiac death and the lack of predictive and efficient strategies to prevent them.

• The proposed immediate low-cost home-defibrillation ,if implemented in AEDs and combined with new wearable pulse sensor devices-is the only strategy that will be successful


A.Teddy Weiss has completed his MD from the Hebrew University School of Medicine and Cardiology residency at Hadassah hospital in 1976 and postdoctoral studies at Cedars-Sinai cardiology center in Los-Angeles and since then- a fellow of the American College of Cardiology. He was the director of the intensive coronary care unit in Hadassah for 30 years and now-director of cardiac rehabilitation unit. He has published more than 150 papers in reputed journals with a great impact in nuclear cardiology and pre-hospital thrombolysis for acute myocardial infarction.
