Use of AEDs in the Home Yields High Survival Rates

Most cases (80%) of sudden cardiac arrest (SCA) occur in the home. A new suggests that deployment of automated external defibrillators (AEDs) in homes may be an important additional strategy for SCA treatment. Using a prospectively-designed post-market study, researchers identified 25 cases in which a privately owned AED was used to treat SCA, including two uses on children.

Results indicate:

Can "Heel CPR" Help?

LOS ANGELES--Is “Heel CPR” a viable alternative to “Hands-Only CPR” for lone rescuers, who may become fatigued and unable to apply adequate force while waiting for EMS to arrive?

Fernando Perez, MD, and Robert H. Trenkamp, Jr., EMT-P, from “Saving Lives in Chatham County explored this question and presented their research earlier this month at the American Heart Association Resuscitation Science Symposium. 

Trenkamp, who serves on the Sudden Cardiac Arrest Foundation Board of Directors, reported the results of examining the duration an adult could maintain two-inch deep chest compressions at a rate of at least 100 per minute using “Hands-Only” and then Pedal Compressions (“Heel CPR”) in two sequential tests. 

Novel Low Energy ICD to be Studied

A novel electrotherapy greatly reduces the energy needed to shock a heart back into rhythm, potentially making ICDs more acceptable to patients.

Blueprint for an airport

If you are one of the 376 airports in the U.S.A. and don't have a program like this, here are the instructions:

On October 17, a woman and her husband were on their way to the United Airlines ticket counter in Terminal 2 when the woman began experiencing difficulty breathing and collapsed. A United Customer Service Agent immediately began assisting and called out for anyone who knew CPR. A nurse practitioner was in the airport and rushed over. The United employee then called for assistance and found Airport Police Officer Eric Davis. Officer Davis immediately responded by grabbing an AED. Both the nurse practitioner and Officer Davis placed the Automated External Defibrillator (AED) on the woman and administered it. The woman then began breathing on her own, and all stayed with her until a rescue crew from the Phoenix Fire Department arrived on-scene. The woman was stabilized for transport to a local hospital.

ICD Battery Alarms Us All

You may have noticed we posted an article (linked to the original Reuters piece) concerning a technology breakthrough that could have major impact on future need for ICD and pacemaker batteries.

Now we have another story to tell on the subject.

What does an ICD battery alarm sound like? Alarm you say, what alarm?
Ah, if you have an ICD, then one day you are likely to hear this sound or something similar.

Sudden Cardiac Death Risk May Be a Family Matter

Relatives of young sudden cardiac death victims appear to have a greater risk of cardiovascular disease than the general population, a Danish study showed.

During up to 11 years of follow-up, there were 292 incident cases of cardiovascular disease in a cohort of relatives, higher than the 219 expected in the background population (standardized incidence ratio 1.33, 95% CI 1.19 to 1.50), according to Mattis Flyvholm Ranthe, MD, of the Statens Serum Institute in Copenhagen, and colleagues.

The risks were particularly high in relatives younger than 35, the researchers reported online in the European Heart Journal.

The findings support a large hereditary component of sudden cardiac death, Ranthe and colleagues argued.

Minority and Suburban Children at Higher Risk of Sudden Cardiac Death

LOS ANGELES -- Among children who suffered sudden cardiac death (SCD), significant risk factors included being black, Hispanic, older than 6 months, and living in the suburbs.

Victoria L. Vetter, M.D., and colleagues reviewed a dataset from 16 states from 2005 to 2009 in records maintained by the National Center for the Review and Prevention of Child Deaths. Among 1,099 cases of child cardiovascular deaths, the team identified 63 percent as SCD and 37 percent as non-sudden cardiovascular death. Prior conditions, identified in 49 percent of the children who died, included congenital heart defects, cardiomyopathy and arrhythmia, with most deaths occurring at home or school (30 percent) or in the hospital (40 percent).

Spring Break Nearly Broke Her

Patricia Harris, Whitsett, NC – 51 at time of event (2010)

Patricia & Ricky Harris

April fools day is not the time to fool around with a heart attack. Not if you live out in the country. And not if you're a Grandmother. Alas, Patricia didn't realize she was suffering a complete blockage of her LAD artery. In men it's called a "widow maker".

A few days before, Patricia's arms had felt sore.
"Like I had been moving furniture!" she said. But she hadn't. She also felt a little out of breath and dizzy.

Tennessee State Football Player Collapses, Dies at Practice

Tennessee State walk-on football player William Wayne Jones III collapsed Wednesday during a non-contact practice and later died, coach Rod Reed said.

Jones, 19, was a freshman defensive back who hadn't played in a game for the Tigers because he was being redshirted.

He had caught a football in the early stages of the practice, which began just after 4 p.m., and was returning the ball to defensive backs coach Ed Sanders when he fell to the grass.

"We didn't think it was anything serious, but the trainers checked on him right away," Reed said.

The trainers found Jones unconscious and without a pulse and immediately tried to revive him, Reed said.

An ambulance was called and Jones was transported to Baptist Hospital. He was pronounced dead at 5:50 p.m.

Reed said he knew of no pre-existing conditions that would indicate Jones' health was at risk.

The players were wearing helmets but not in full gear.

Latest Technology for ICDs & Pacemakers - An Energy-Harvesting Device That Needs No Battery

ICD placement

University of Michigan researchers have found a way to avoid the need to replace an ICD or pacemaker due to battery expiration.

Their research has identified a way to use your own beating heart to power your device. Department of Aerospace Engineering at the University of Michigan in Ann Arbor tested an energy-harvesting device that runs on piezoelectricity (electricity resulting from pressure), and were able to generate more than 10 times the power required by modern pacemakers. And, it is about half the size of batteries now used in pacemakers and includes a self-powering back-up capacitor.

Mission & Vision

The mission of the Sudden Cardiac Arrest (SCA) Foundation is to prevent death and disability from sudden cardiac arrest. The vision of the SCA Foundation is to increase awareness about sudden cardiac arrest and influence attitudinal and behavioral changes that will reduce mortality and morbidity from SCA.
