Why Does Atrial Fibrillation Cause Strokes
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 moreSee 1 more doctor answer
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
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
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 moreSee 2 more doctor answers
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

This can result in increased blood pressure, and it can also cause abnormal heart rhythms, including atrial fibrillation.

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

Not usually: Ms originates in the brain and affects skeletal muscles, causing the person to loose voluntary control of them. It can also affect vision, causing optic neuritis and sometimes blindness, double vision or other visual problems. It can also cause cognitive problems and dementia. However, it doesn't typically affect the heart directly. ...Read moreSee 1 more doctor answer
What makes atrial fibrillation not immediately life threatening while ventricular fibrillation is?
A circuit breaker: The rhythms in the top chamber during atrial fibrillation can reach and exceed 600 bpm. If this were conducted directly to the lower chamber, it would be as fatal as ventricular fibrillation. However, nature built in a circuit breaker called the av node between the two such that only some of the top chamber heartbeats in fibrillation make it to the bottom chamber. ...Read moreSee 1 more doctor answer
Clots and Ischemia: Atherosclerosis, an accumulation of white blood cells within the walls of arteries, typically starts in childhood, artery walls thicken & the opening remains unchanged for decades. Rupture of the endothelial lining over the plaque showers clot inducing tissue into the blood blocking arteries downstream occasionally, clots over the rupture block the opening. Yet majority of events are asymptomatic. ...Read moreSee 1 more doctor answer
