Test your knowledge on atrial fibrillation and the risk of stroke

* Atrial fibrillation is a condition that affects:

• the digestive system
• the knee
• the heart

* Atrial fibrillation patients:

• all feel symptoms
• feel symptoms in 80% of the cases
• are all symptom-less

* Atrial fibrillation can cause:

• a stroke
• skin cancer
• changes to the pupil's color

* Atrial fibrillation can cause a stroke when:

• a clot formed in the heart reaches the brain
• a clot formed in the heart reaches the lungs
• a clot formed in the heart reaches a kindey

* In atrial fibrillation a blood clot can form:

• in the heart because the blood is not flowing well
• in the stomach
• in the liver

* Atrial fibrillation's treatment goals are:

• make the heart recover a regular beat
• avoid blood clots to prevent stroke
• make the heart recover a regular beat and avoid blood clots to prevent stroke

* A blood clot is:

• an air bubble that forms in the blood
• formed by platelets, fibrin and red blood cells
• a build up of cholesterol

* In a normal heart beat:

• atria and ventricles contract with a regular rhythm
• only the atria contract
• only the ventricles contract

* During atrial fibrillation:

• the atria and the ventricles contract too slowly
• the ventricles don’t contract
• the atria quiver while the ventricles contract with an irregular rhythm

* Atrial fibrillation is an important threat for:

• the legs
• the brain
• the teeth
