Sudden Cardiac Arrest »
Introduction to sudden cardiac arrest
A natural disaster hits, the power goes off and the lights go out. It's a
common scene that plays out during hurricane and tornado seasons, and it's very
similar in trying to explain sudden cardiac arrest. The heart sustains an insult,
the electricity is short circuited, the heart can't pump, and the body dies.
The heart is an electrical pump, where the electricity is generated in
special pacemaker cells in the upper chamber, or atrium, of the heart. This
electrical spark is carried through pathways in the heart so that all the muscle
cells contract at once and produce a heart beat. This pumps blood through the
heart valves and into all the organs of the body so that they can do their work.
This mechanism can break down in a variety of ways, but the final pathway in
sudden death is the same: the electrical system is irritated and fails to
produce electrical activity that causes the heart to beat. The h...

I have congenital aortic stenosis. It was diagnosed when I was 6 years old after a noticeable heart murmur. It was mild to moderate through grade school and middle school. I was a pretty normal kid, playing sports and all that. I went in annually for an Echo/EKG. At age 13, they noticed it was getting worse and becoming severe (.9 cm opening), so we elected to do the balloon catheterization. After monitoring the results, it was determined that it was NOT successful, but we tried again with the balloon catheterization at age 15. This one was a success. The valve opening was estimated at 2.1 cm. I was back to "normal" again but was not allowed to play basketball/soccer/football in high school. This was a drag because I was and am very athletic. I've monitered my aortic stenosis every since, and have seen the valve slowly deteriorate over time. From the age of 15 to age 30, it has now gone down from 2.0 cm to 1.0 cm. I can still run and jump and play pickup basketball. Once I get a sweat going, I can maintain moderate exercise like basketball or hiking. I cannot however go jogging, or use a treadmill, as I will very quickly tire out. I'm now considered moderate to severe and have Echo/EKG every 6 monhts, in the next couple of years I will have to have another operation. I'm debating on which one. I'm kind of leaning towards valve replacement, but I don't really like my current options. I hope and pray that more science can be developed so that I can live a long and healthy life and raise a family. Published: December 18 ::
