Every year around 75,000 Americans learn that they have atrial fibrillation (AFib)—the most common type of arrhythmia, or abnormal heart rhythm. While the abnormal heart rhythm itself isn’t generally serious; abnormal blood flow and strain to the heart can lead to serious medical conditions. These conditions can be deadly—having AFib doubles a person’s risk of death. It also increases the risk of stroke by 500% and 70% of AFib patients who suffer from a stroke will die. This makes recognizing the signs and symptoms and getting appropriate treatment critical.
