Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

How can food affect atrial fibrillation?

How can food affect atrial fibrillation?

Food can affect meds: Afib is a rythm that can be very fast and can cause a stroke from blod clots going to the brain. Many patients are on Coumadin (warfarin) a blood thinner that works through vitamin k. So if the patient eats green leafy veges and other foods high in vitamin k , it can reverse the Coumadin (warfarin) and make pt suseptable to stroke. Foods and items high in caffiene like coffee chocolate etc can stimulate the heart rate. ...Read more

What are the common symptoms of atrial fibrillation?

Commonly people notice fatigue and their exercise capacity is mildly reduced. Sedentary people usually don't notice any change. Younger people & folks with their 1st bout tend to be more aware. Frequent bouts and older people are less likely to notice. ...Read more

In which case we can found a regular atrial fibrillation?

Unclear: I am sorry, but I do not understand what you are asking. Atrial fibrillation is never normal. The rate can be controlled with medicine if it is present all the time. Some people have atrial fib at times but not at others, and sometimes the atrial fib. can be converted to a normal rhythm with treatment. Please ask your question again, with a clearer question that we may be able to answer better. ...Read more

How to know what is atrial fibrillation and is it serious?

Atrial fibrillation: Afib is a rapid irregular heart rhythm which can decrease heart efficiency as much as 20% in some patients. It can also be associated with clotting and clots travelling around the body to cause stroke or other problems. Some people have atrial fibrillation as their normal rhythm. Talk to your dr. About it if you have it. ...Read more

Is atrial fibrillation a serious condition? My friend is 45 and has it.

Not usually: Atrial fibrillation may be a consequence of structural abnormalities of the heart, which can indeed be serious. However, if the rhythm disturbance is the only abnormality then it can usually be controlled sufficiently that the patient can be free of symptoms. In older patients with af there is significant risk of stroke, but this too can be mitigated by treatment to reduce blood clots. ...Read more

Funny how a diagnosis doesn't mean much till you have it. What is atrial fibrillation?

Funny how a diagnosis doesn't mean much till you have it. What is atrial fibrillation?

Electrical chaos: The electrical impulses in the upper chambers of your heart (mostly originating from the left side) are completely chaotic leading to a quivering motion of these chambers instead of their typical, coordinated pumping function. The lower chambers beat erratically, as the electrical impulses bombard them in a haphazard way. See a cardiologist or an elelctrophysiologist. ...Read more

What is the difference between atrial fibrillation and nonvalvular atrial fibrillation?

Afib: Afib is the most common heart rhythm disturbance that we treat as cardiologists and can occur in a number of clinical settings and in association with other diseases both cardiac and non-cardiac. Non-valvular atrial fibrillation refers to atrial fibrillation that does not occur in the setting of mitral valve disease such as mitral stenosis or mitral regurgitation. ...Read more

Can stress cause atrial fibrillation?

Can stress 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

Will stress cause atrial fibrillation?

Will stress cause atrial fibrillation?

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 more

How can tyramine cause atrial fibrillation?

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
