What is atrial fibrillation and how does it affect the heart?

Atrial fibrillation (AF) is a type of arrhythmia, where the heart beats irregularly. This condition can lead to poor blood flow and increase the risk of stroke and heart-related complications. Symptoms may include palpitations, dizziness, fatigue, and shortness of breath. For British South Asians, the prevalence of AF can be higher due to risk factors such as high blood pressure and diabetes. It's essential to consult your GP if you experience these symptoms. Treatment options may include lifestyle changes, medications, or procedures to restore normal heart rhythm. The NHS provides guidelines and resources to manage AF effectively.
