Would an echocardiogram detect an atrial fibrillation?

Yes. Although an echocardiogram can detect atrial fibrillation, there are easier ways to diagnose it. Your doctor should be able to tell if your pulse is irregular and confirm afib with a simple ekg. Atrial fibrillation sometimes makes interpretation of an echocardiogram more difficult if the heart rate is too fast.
No. No, not unless you happened to be in af at the time of the echo. It can detect signs that a heart is prone to atrial fibrillation, like enlarged atria.

In a fit, healthy 18 year old. Whats the worst that could happen if I have atrial fibrillation? Normal echocardiogram, ekg, but didn't have palps during

Nothing. Other than the sensation of palpitation, atrial fibrillation in young healthy persons are benign. Since in this age group the arrhythmia is often associated with a very rapid heart rate they often require treatment to control heart beat or intervention to convert them back to regular rhythm.

How dangerous could atrial fibrillation be in a healthy, very fit 18 year old with no other problems? Normal echocardiogram, ekg, and stress test

Confused. Having a normal EKG essentially rules out having atrial fibrillation.
Not likely. Atrial fibrillation is not as common in young individuals as in elderly. Sometimes benign arrhythmias are over diagnosed as atrial fibrillation. In your case how was your atrial fibrillation diagnosed? Otherwise atrial fibrillation remains a significant medical condition with a variety of possible complications, the most common being stroke.

Is atrial fibrillation hereditary?

No. Congenital heart problems can be inherited and this can lead to afib. But afib itself is not.
Possibly. While there are no clear genes identified (and in fact we know relatively little about an issue that plagues so many people) there clearly are families in which atrial fibrillation is more common through the generations. So while this is far from medical fact, most physicians who treat a lot of atrial fibrillation would argue that there is likely some type of inheritance.
Rarely. Familial AF is described and little is known so far. Different genes have been implicated and it probably constitutes 5% or less of AF cases.

Why is atrial fibrillation dangerous?

Cva, mi. 1 - if the rate goes too fast...This can become a problem 2 - more commonly, when they beat so erratically, it gives an opportunity for the blood to clot in the atria, and then when that clot is pushed into the ventricles it can be pushed into the circulation where it may cause an mi or cva.
Causes strokes. Atrial fibrillation causes stagnation of blood in the atrium contributing to the formation of clots there which may travel to the brain causing a stroke or cva or sudden death.
Generally, It's Not. Afib isn't a fatal condition and while people who have it live shorter lives, most of that is because they also have other issues. It's problematic if the lower chamber (ventricles) are driven too fast (>130/min on ongoing basis, usually) which can result in impaired pumping function of the heart (rate related cardiomyopathy). Many people also have disabling symptoms from the fast/irreg heart rate.

Can an atrial fibrillation be lethal?

Yes. When the heart is in atrial fibrillation, it causes blood to clot in the chambers of the heart. These clots can flow out of the heart and cause strokes. Strokes can be lethal. Doctors sometimes put people on a blood thinner called warfarin (coumadin) to help prevent clots in people with atrial fib. It's a serious condition, but manageable! Cheers!
Only if… Only if the atrial rate is conducted in a very rapid fashion to the lower chamber. Your heart has built-in protection to keep this from happening. However, patients with a condition known as Wolff-Parkinson-White sometimes lack this protection and under the right circumstances can die as a result of atrial fibrillation.

How is atrial fibrillation diagnosed?

Ekg. Multiple different ways such as physical exam, most of them usually have to be confirmed by e k g.
EKG /Physical exam. Different ways. Listening to the heart there is obvious irregular rhythm with irregular rate. The electrocardiogram is diagnostic. Some times atrial fibrillation may appeared transiently or paroxystically. A holter monitor or cardiac monitor could show the characteristic features of the EKG changes.

What does atrial fibrillation feel like?

Rapid heart beat. You may feel that your heart is racing, sometimes you may feel like passing out, you feel irregular heart beat.

Is atrial fibrillation dangerous to have?

It can be. It can lead to stroke unless you take anticoagulants.
It depends. Appropriate management can lower the risk. Specifically, the heart rate needs to be controlled and stroke risk needs to be addressed. Specific guidance should be available from your physician.
It can be. Increased stroke risk is the major consideration here. Talk to your cardiologist about what yours is & whether you should be on blood thinners or just Aspirin (for lower risk patients).
