Understanding Atrial Fibrillation
What is the difference between supraventricular arrhythmias (SVT) like atrial flutter and atrial fibrillation?
In supraventricular or "atrial arrhythmias," the heart rate is sped up by abnormal electrical impulses starting in the atria or surrounding the AV Node, the tissue between the atria and the ventricles.
What are the causes and risk factors of atrial arrhythmias?
High blood pressure, coronary artery disease, and other heart and lung conditions are associated with atrial arrhythmias
What are symptoms of atrial arrhythmias?
Symptoms of atrial arrhythmias vary. Some people feel a flutter in their chest, while others feel dizzy, faint, or short of breath.
How is atrial arrhythmia diagnosed?
To diagnose atrial arrhythmias, your doctor will typically start with an electrocardiogram (ECG) test.
How is atrial arrhythmia treated?
Doctors may prescribe medications, cardioversion, surgery, a pacemaker, or a combination of these therapies for the treatment of atrial arrhythmias.
