Atrial flutter is another type of abnormal heart rhythm. It happens when a short circuit causes the upper chambers of your heart (atria) to pump too fast. In atrial fibrillation, the heart's electrical impulses come from multiple areas, causing the atrial walls to contract instead of contractin...
Stroke is a typical disease which occurs when a blood clot(凝块)blocks an artery(动脉) or a blood vessel(血管) breaks,interrupting blood flow to an are a of the brain.When either of these things happens,brain cells begin to die and brain damage occurs.Abilities controlled by that are a ...
A natural history of atrial fibrillation and dementia: What happens to those who remain on anticoagulation and those who do not?A.R., OrkabyA., OzonoffJ.I., ReismanA.J., Rose
What is the pathogenesis of atrial fibrillation? If the left ventricle stops working in the heart, what will happen? How does coronary artery disease cause atrial fibrillation? How does valvular heart disease cause atrial fibrillation? When the ventricular walls contract, what happens to the bicuspid...
5 Good results have still been reported when the rotor/focal source happens to lie at a site where the basket makes contact.6 In these cases, many electrodes away from this site may not be in contact, and basket repositioning is needed to map the entire chamber. Future...
Cerebral palsydescribes the condition where a developing infant's brain is deprived of oxygen and fails to develop normally. This may occur in the uterus before birth or may be due to an injury or illness that happens within the first couple of years of life. Often, it is an infection or...
Atrial fibrillation that happens in younger people (under 60 years old), without an obvious cause is called lone AFib. Lone AFib can be triggered by exercise, eating, sleeping, and alcohol. Sometimes it comes and goes on its own and may not need immediate treatment. Consult your doctor. ...
Atrial fibrillation is a condition that affects the heart- specifically the atria, hence the name. It can be caused by abnormalities or damage to the heart. Answer and Explanation:1 Atrial fibrillation is known as an irregular heartbeat and can lead to stroke, heart failur...
Stenosis happens when you have a narrowed or hardened valve that restricts the amount of blood passing through it. Regurgitation occurs when blood leaks back into the ventricle through poorly sealing leaflets. In either scenario, your heart must pump harder to push the proper amount of blood throu...
