What are supraventricular cardiac arrhythmias?
Your heart is comprised of four chambers: two upper compartments known as the atria and two lower ones known as the ventricles. An arrhythmia, or abnormal heart rhythm, may begin in various locations within the heart.TypesWhile there are a wide variety of cardiac arrhythmias, they can be classified into two categories: ventricular and supraventricular.IdentificationVentricular arrhythmias begin in one of the two ventricles, while supraventricular arrhythmias originate in the part of the heart above the ventricles. Supraventricular arrhythmias typically occur in the atria, but may also begin in the electrical conduction pathways of the heart.ExamplesCommon supraventricular arrhythmias include supraventricular tachycardia, which occurs when a part of your atria sends abnormal electrical signals that speed up your heart rate, and atrial fibrillation, a rapid and irregular heartbeat in which muscle fibers in the atria contract on their own.
