Atrial fibrillation (AFib) can, in rare cases, cause sudden death. AFib is an irregular heart rhythm caused by abnormal electrical signals in the atria, or upper chambers, of the heart. This can lead to a number of symptoms, including palpitations, shortness of breath, and lightheadedness. In some cases, AFib can cause a stroke or heart attack, both of which can be fatal.
In addition, AFib can cause a rapid and chaotic heartbeat known as ventricular fibrillation, which can lead to sudden cardiac arrest. During ventricular fibrillation, the heart’s electrical signals become so chaotic that the heart stops beating, leading to a lack of blood flow to the brain and other vital organs. This can be fatal if not treated quickly.
The risk of sudden death from AFib is low, but it increases with age and if the condition is left untreated. Other factors may also increase the risk, such as high blood pressure, prior heart attack or stroke, and certain medications.
To reduce the risk of sudden death due to AFib, it is important to get regular medical care. Patients should also talk to their doctor about lifestyle changes, such as quitting smoking, exercising regularly, and eating a healthy diet. Additionally, medications can help to reduce the risk of stroke and other complications of AFib.
