Health Conditions Discover Plan Connect. Medically reviewed by Debra Sullivan, Ph. What causes heart murmurs and atrial fibrillation? How are heart murmurs and atrial fibrillation diagnosed? Treatment for heart murmurs. Treatment for atrial fibrillation. This raises your risk for a stroke.
Hall, who compares the lower levels of the heart to water in a stagnant pond. How your heart sounds is just one part of making an atrial fibrillation diagnosis. The gold standard is the electrocardiogram EKG. This is a test that measures the electrical activity of the heart, creating a graph of your heartbeat. Even though an afib heart can cause significant symptoms, such as a quivering heart sensation, dizziness, and chest discomfort, a significant number of people do not know they have atrial fibrillation.
A study of adults published in the journal Stroke found that of those who had atrial fibrillation, only about 60 percent were aware of it. If you've had some of the symptoms of atrial fibrillation, don't try to hear an afib heartbeat on your own. If you have an episode of atrial fibrillation during an ECG, your abnormal heart rate will be recorded. This will confirm the diagnosis of atrial fibrillation and rule out other conditions.
But often it can be difficult to capture an episode of atrial fibrillation, so you may be asked to wear a small portable ECG recorder. The recorder will either trace your heart rate continuously over 24 hours or when you switch it on at the start of an episode.
Page last reviewed: 17 May Next review due: 17 May The intrinsic conduction system sets the basic rhythm of the beating heart by generating impulses which stimulate the heart to contract.
Electrical signals direct your heart to pump the right amount of blood for your body's needs. The signals begin in an area called the sinoatrial node also called the sinus node or SA node. In atrial fibrillation, the electrical impulse of the heart is not regular.
This is because the sinoatrial node no longer controls the heart rhythm. In atrial flutter, the ventricles lower heart chambers may beat very rapidly, but in a regular pattern. Symptoms may start or stop suddenly. This is because atrial fibrillation may stop or start on its own.
The health care provider may hear a fast heartbeat while listening to your heart with a stethoscope. Your pulse may feel fast, uneven, or both. The normal heart rate is 60 to beats per minute. In atrial fibrillation or flutter, the heart rate may be to beats per minute.
Blood pressure may be normal or low. An ECG a test that records the electrical activity of the heart may show atrial fibrillation or atrial flutter. If your abnormal heart rhythm comes and goes, you may need to wear a special monitor to diagnose the problem. The monitor records the heart's rhythms over a period of time. Cardioversion treatment is used to get the heart back into a normal rhythm right away. There are two options for treatment:.
A procedure called radiofrequency ablation can be used to scar areas in your heart where the heart rhythm problems are triggered. This can prevent the abnormal electrical signals that cause atrial fibrillation or flutter from moving through your heart. You may need a heart pacemaker after this procedure.
All people with atrial fibrillation will need to learn how to manage this condition at home. People with atrial fibrillation will most often need to take blood thinner medicines.
