Question

Question 10 0.5 points Saved Which of the following describing the relationship between atrial fibrillation (A-fib) and stroke is true? A-fib patients are at higher risk for stroke due to the weakness of the blood vessels which carry blood to the brairn. O A fib patients are at a higher risk of stroke due to due to aberrant electrical signals which can reach the brain. O A fib patients are at a higher risk of forming clots which could result in a stroke. O There is no link between A-fib and stroke

Answer 1

The correct answer is in the third option.

A fib patients are at a higher risk of forming clots which could result in a stroke.

The explanation is as follows:

Atrial fibrillation is a condition in which the atria of heart beats irregularly and at an abnormally higher rate. The normal heart beats regularly at normal rate. The atrial fibrillation increases the risk of having a stroke by nearly five times. The irregular heartbeat in this atrial fibrillation is associated with irregular flow of blood in the body. This irregular circulation leads to some areas where the blood flow is impaired and blood becomes stagnant. This stagnant collection of blood increases the chances of clot formation. This clot can be dislodged from that place. If this clot enters the brain during the blood circulation, it can cause a blockade of the vessel causing stroke.

This is a brief explanation. Hope this helps you out. Please feel free to give your feedback and if you need further explanation on this topic. Thank you and have a great day.
