Will Hypovolemia Cause Atrial Fibrillation
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 more
HTN, CAD, Hyperthyroi:
High blood pressure
heart defects you're born with (congenital)
an overactive thyroid gland or other metabolic imbalance
exposure to stimulants, such as medications, caffeine or tobacco, or to alcohol
sick sinus syndrome — functioning of the heart's natural pacemaker
emphysema or other lung diseases
previous heart surgery
stress due to pneumonia. ...Read more
Excess alcohol: Heavy drinking iver time can lead to cardiomyopathy as alcohol works as a myocardial suppressant but even in smaller but usually excessive quantities it can cause atrial fibrillation due to its dehydrating and electrolyte depleting effects. This is often referred to as "holiday heart". ...Read more
Clot formation: Because blood in the left atrium is not propelled forward normally during atiral fibrillation, it allows for the formation of clots. Small areas of blood pooling resembling little eddy currents allow blood to slow down and form clots. If one of these clots is then propelled forward it can travel to the brain, become lodged in a blood vessel and cause a stroke. A clot the size of a pinhead can do it. ...Read more
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
Vasoactive amine: Tyramine is derived from the Amino Acid tyrosine. Increased tyramine can cause increases in dopamine, Epinephrine & norepinephrine (particularly when taking 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 more
No: My answer would be NO. I reviewed reliable sources and atrial fibrillation is not listed as a side effect. I found a website with a very unscientific survey among people taking lisinopril who have developed afib, but without any scientific rigor at all. Most people that need lisinopril already have other reasons to develop atrial fibrillation. I hope this helps. ...Read more
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 more
Standstill: The extremely rapid rates of atrial fibrillation are in fact so fast that they create two problems: the top chamber is not mechanically moving very far at all, so it cannot shake clots loose, and the overactive atrial tissue secretes chemicals which increase the likelihood of clot formation. These processes come together to substantially increase stroke risk. ...Read more
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
Only in a Very Few: Generally, the answer to this is a very solid "no." this is a rare complication of people with another condition (on top of their afib) called wolff-parkinson-white syndrome (or wpw). In certain patients having both conditions, the top chamber is too-well connected to the bottom and can trigger ventricular fibrillation. ...Read more
Why the atrial fibrillation causing thromboembolic phenomena while atrial flutter don't cause it?
Short answer: Atrial fib has increased risk secondary to irreg. Firing of atria and valves causing damage to blood cells. In flutter there is a more regular rate and atrial contractile function offers some protection but there is still a slightly increased risk. In chronic flutter, coagulation is necessary given the risk of stroke is the same as atrial fib. Pts with chronic flutter often have a fib as well. ...Read more
What causes atrial flutter? What is the cause of my atrial fibrillation or atrial flutter? Will my condition go away on its own?
What causes atrial fibrillation? Is stress the main cause of atrial fibrillation, and is it genetic?
Not Really: The main cause in ~90% of cases from young persons like you is extra heartbeats starting in structures called the pulmonary veins. Sometimes that's all it is; more often than not though, the top chambers (atria) also have dilation and scar tissue which helps sustain the fib once it starts. Only a small portion of afib is clearly known to be genetic. Stress triggers extra htbeats -? -> fib. ...Read more
