Atrial Fibrillation

The most common kind of arrhythmia is called an atrial fibrillation, which results in a racing heartbeat, usually averaging between 300 and 600 beats per minute. Atrial fibrillation occurs when the atrioventricular (AV) node receives several electrical impulses at once from the upper chambers of the heart. In these cases, the AV node typically only allows a few impulses to successfully travel to the lower chambers of the heart. This results in a heart that appears to be racing or beating chaotically, but a heart that is not pumping enough blood throughout the rest of the body.

Atrial fibrillation can be a sign of a deeper problem, such as high blood pressure, heart disease, lung disease, heart failure, cardiomyopathy, or a pulmonary embolism.

Chronic untreated atrial fibrillation can create serious consequences for the patient. This arrhythmia can lead to blood clots, stroke, heart failure, or sudden.
