What causes atrial fib?

Many causes. There are many factors that can lead to atrial fibrillation. Common predisposing conditions include hypertension, heart failure, sleep apnea, and genetic predisposition.
Many causes. Most of the time however the cause is not clear. Electrical conductive disease, thyroid disease, coronary artery disease, cardiomyopathy, alcohol, drugs like amphetamines and cocaine or other speed like drugs. Also severe infections or physiologic stress can it also.These are but a few.
Atrial fibrillation. The two most common causes of atrial fibrillation are hyperthyroidism (overactive thyroid) and degenerative disease of the cardiac conduction system as we get older. Other causes include heart surgery, alcohol (chronic intoxication), and conditions which enlarge the atria (like heart valve problems).

Can hyper-thyroidism cause atrial fib?

One Factor. Although I am a dentist, I am we'll versed in basic medicine. One factor that could cause atrial fibrillation is a hyper-active thyroid. I would suggest at your age a visit to the cardiologist or an internist to determine the cause and best treatment options for you. Read more...
Yes. Atrial fibrillation is associated with hyperthyroidism. You have other comorbidities that may also contribute ie smoking, high cholesterol. You will need therapy for the thyroid either meds or surgery or radioactive iodine treatment. You will also need therapy for atrial fibrillation usually beta blockers. Read more...

Can anxiety cause atrial fib?

Yes. Anxiety/stress may be associated with catecholamine excess (adrenalin) which increases automaticity of the heart (irritability) which can encourage the development of afib. Read more...

Mother in law has atrial fibrillation but cannot handle blood thinners (they cause her bleeding issues). What else can treat Atrial fib besides blood thinners?

Ablation. she can be seen by a EP cardiologist to be evaluated for atrial ablation. she may or may not be a good candidate. also based on her risk factors rate control with B-blockers (IE metoprolol) may suffice as a proper treatment for A fibrilation. Read more...
Prevention/treatment. Blood thinners are used mainly for stroke prevention in patients with atrial fibrillation. There are numerous proposed personal scores/scales based on which they are recommended. The bleeding risk is usually the limiting factor in the use of blood thinners. Atrial fibrillation treatment is a different topic and it involves mainly controlling the heart rate/ heart rhythm. Read more...
Quite a few! without directly reviewing the patients full history, labs, etc. I cannot give specific medical advice BUT there has been an entirely new group of treatments and might be less risky for some patients. https://www.heart.org/HEARTORG/Conditions/Arrhythmia/AboutArrhythmia/Atrial-Fibrillation-Medications_UCM_423781_Article.jsp dabigitran.

Can Diastolic Dsyfunction cause Atrial Fib with symptoms? Can it cause Bradycardia with symptoms? What is the best Treatment plan for these types

Yes. Diastolic LV dysfunction can cause atrial fibrillation particularly if the left atrium becomes enlarged. Diastolic dysfunction cannot cause bradycardia per se. Often the best treatments of diastolic dysfunction can cause bradycardia; such as beta blockers or calcium channel blockers. We do not have any real good treatment specifically for diastolic dysfunction. Ranolazine has shown some promise. Read more...
Not necessarily. Diastolic dysfunction is due to problem with compliance of the heart while paroxysmal atrial fibrillation are related to ectopic pacemaker cells, accessory pathways, usually found in the left atrial portion of the heart proximal to the pulmonary veins, which is often treated by radiofrequency catheter ablation. Chronic atrial fibrillation can lead to diastolic dysfunction. Read more...

Is it common for teenagers to have atrial fib?

No. Af is a disease that become more common after age 50. It is unusual, but not especially rare, to have af before this age. Often other conditions can be found that trigger af in young people - like hyperthyroidism, caffeine, alcohol, valve disease, etc. Sometimes af can occur "out of the blue" in young people - usually referred to as "lone af".

What should I do if my atrial fib intermittent?

See your cardilogist. An intermittent atrial fib can be dangerous because of its unpredictability. Read more...
Depends. Possibly nothing but it depends on how often and severe it is. The main issue is rate control meaning the prevention of it going fast. There is also the risk of stroke prevention as that is one of the major concerns in Afib and is treated with anticoagulation. There are are all things to discuss with your doctor. Read more...

Is it dangerous to travel to high elevation.10000 if have atrial fib and hi B.P. well controlled?

Not necessarily. Traveling to 10000 feet should be OK. See your doctor before you go, because they may want to prescribe you Diamox (acetazolamide) to prevent altitude sickness. Hope this helps! Read more...
Altitude. Altitude sickness can be severe unless appropriately acclimatized,Hypertension and AF if controlled are not specific contraindications to higher altitude travel. Read more...
