What is ventricular fibrillation?
The heart beats when electrical signals move through it. Ventricular fibrillation (ven-TRIK'u-ler fib"rih-LA'shun) ("V fib") is a condition in which the heart's electrical activity becomes disordered. When this happens, the heart's lower (pumping) chambers contract in a rapid, unsynchronized way. (The ventricles "flutter" rather than beat.) The heart pumps little or no blood.
AHA Scientific Position
Ventricular fibrillation is very serious. Collapse and sudden cardiac death will follow in minutes unless medical help is provided immediately. If treated in time, V fib and ventricular tachycardia (ven-TRIK'u-ler tak"eh-KAR'de-ah) (extremely rapid heartbeat) can be converted into normal rhythm. This requires shocking the heart with a device called a defibrillator (de-FIB'rih-la-tor).
Today one effective way to correct life-threatening rhythms is by using an electronic device called an implantable cardioverter-defibrillator. This device shocks the heart to normalize the heartbeat if the heart's own electrical signals become disordered.
My advice is NOT to have one if at all possible.

I m 25. My Heart stopped unexpectedly last year. They where unable to figure out why. They installed and (ICD) exactly a year and a day later (yesterday) it went off because my heart was racing. I have no idea if it was ventricular tachycardia or not. I was put on IC Metoprolol Tarta. I was wondering if there were any side effect besides dizziness. I was also wondering if these slight sensations with my heart and chest are due to the shock yesterday or the medicine, or both. Also the (ICD) went of more specifically because the top two chambers of my heart were beating faster them the lower two.
My 9 year old had a screening EKG in order to be prescribed an ADD medication and the results were not normal. My son is adopted from Guatemala and I know nothing of his family s medical history or the nirth mother s behavior during pregnancy. The report indicated soemthing about possible ventircular problems and an emlargement or thieckening of the heart. I did not see the report, the neirologist who ordered the EKG read it to me over the phone. I am taking him to see a pediatric cardiologist next week,but in the meantime, I am wondering how much to worry. (My son appears healthy, is of average height and below average weight.)
