This clot can travel to the brain and block a vessel there, causing a stroke.īlood-thinning medicines help reduce this risk. What are possible complications of atrial fibrillation? Sleep study, when obstructive sleep apnea is suspected.Blood work, to check for thyroid levels, diabetes, and possible health conditions.Cardiac stress testing, to check the blood flow in the heart.Echocardiogram, to check the hearts structure and function.Other tests might be used to help plan treatment. This can monitor for arrhythmias over several years.

If your symptoms are very infrequent, you may have a small implantable heart recording device called a loop recorder implanted under the skin just over the heart. This measures and records your ECG as you go about your daily activities, allowing your healthcare provider to assess your heart's activity over time. If your arrhythmia symptoms come and go, you might need to wear an ECG Holter monitor or event recorder for 24 - 48 hours or longer. In some cases, the diagnosis can be made based on this test alone. Healthcare providers use this test to study the heart signal and rhythm. You may be sent to a cardiologist for more assessment and treatment.Īn electrocardiogram (ECG) is very important for a diagnosis. An internist or primary care healthcare provider will often makes the diagnosis. This is not yet fully understood.ĭiagnosis starts with a health history and physical exam. This is because of differences in genes they inherited from
Running marathons, can develop atrial fibrillation. People who do a lot of repeated vigorous endurance exercises, such as Some of the risksĭuring an infection or right after surgery. There is a range of things that can increase this risk.
Problem that changes the way the heart handles electricity. This is why AFib greatly increases the risk for stroke. These clots can then be pumped out of the heart and travel to the brain,Ĭausing a stroke. But they haveįound that during AFib, blood can pool inside the lobes increasing the risk of formingīlood clots. This pouch is often large with severalĭoctors don't fully understand the physiological purpose of this pouch. Referred to as the left atrial appendage. That's because the left atrium has a pouch in the muscle wall, This pooling can cause blood clots to form inside the heart. The ventricles may not be able to pump blood efficiently to the body.īlood pooling in the heart because the blood is not pumped efficiently from chamberĬhamber. The amount of blood pumped out to the body will vary with each heartbeat. The contraction of the atria and the ventricles is no longerĬoordinated. It causes them to contract irregularlyĪnd sometimes quickly. Signals are then transmitted to the ventricles. This causes the atria to quiver (fibrillate). The ventricles contract to move blood out to the body.Įlectrical signals that come from outside the SA node causing the atria to contractĭisorganized fashion. The atria contract with each heartbeat to move blood into the ventricles, As it travels, the signal triggers the chambers of the heartĬontract. Tissues call the AV node, to reach the left and right ventricle, the two lower pumpingĬhambers of the heart. From the right atria, it travels to the upper-left fillingĬhamber of the heart (left atrium) and from there, it passes through another node TheseĬells are referred to as the sinoatrial (SA) node.
Normally, a specific groupĬells in the right upper heart chamber gives the signal to start your heartbeat. Most common type of abnormal heart rhythm (arrhythmia).
