Causes Of Fibrillation
Atrial fibrillation: Atrial fibrillation , or afib, is a very common rhythm disturbance, the most common in this country. It is most often associated with hypertension, but can also be associated with valvular disease specifically mitral valve disease. It can be treated with either rate control or converting back to the normal sinus rhythm. Patient are often placed on blood thinners to prevent complications. ...Read moreSee 1 more doctor answer
Generally, not: If there is no underlying cardiac problems that may predispose one to atrial fibrillation, it would be unusual for stress to be actual cause; however stress can be the underlying to so many maladies, that one never says never. If one develops atrial fib, must look for underlying heart disease, and--even it none is found-be treated for it by cardiologist specializing in cardiac rhythm disorders. ...Read moreSee 1 more doctor answer
May provoke: Stress alone usually doesn't cause the arrhythmia unless there is some underlying predisposition. Having said that, someone with the predisposition, can have recurrences, especially with acute stress. You should make every effort to manage with stress-reducing techniques. ...Read moreSee 1 more doctor answer
Alcohol=toxic : Excessive alcohol can be toxic to your body including the heart. The cardiac cells that make up the sinus node (the automatic pacemaker) on the top part of your heart, as well as the rest of the heart are subject to the toxic effect of alcohol and thus can fibrillate(shaky) just as your brain cells do that make you unable to walk-a-straight-line test! cut it down. Drink responsibly. Good luck. ...Read moreSee 1 more doctor answer
Vasoactive amine: Increased tyramine can cause increases in dopamine, Epinephrine & norepinephrine (particularly when taking a type of drug called an mao-inhibitor). This can result in increased blood pressure, and it can also cause abnormal heart rhythms, including atrial fibrillation. The 1st reported case of atrial fibrillation caused by tyramine was in grimsby, england, in 1987. ...Read more
Yes: Atrial fibrillation is an irregularly irregular heart rhythm , it can happen when the atrium( upper chamber of the heart) is enlarged. Hypertension causes the heart to work harder, develops hypertrophy to have enough force to push the blood forward from the ventricle ( lower chamber of the heart); the atrium in turn enlarges to push blood to ventricle and eventually dilates then a-fib develops. ...Read moreSee 1 more doctor answer
Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more
