What is Arrhythmia? Atrial fibrillation (AFib), is a common form of arrhythmia. The condition occurs when there are erratic electrical signals between the upper chambers of the heart, or atria. These signals confuse the heart’s natural rhythm, causing the atria to squeeze too quickly. As a result, the heart fibrillates, or quivers. Learn More About AFib Symptoms Triggers Risks What are the symptoms of atrial fibrillation (AFib)? Symptoms of atrial fibrillation (AFib) can vary. Some people experience AFib intermittently (occasionally), while others have persistent episodes that happen more frequently or continuously. Common symptoms include heart palpitations — often felt as a fluttering, racing, or pounding heartbeat — along with chest pain, dizziness or lightheadedness, shortness of breath, fatigue, and general weakness that can make physical activity more difficult. Can stress or caffeine trigger arrhythmias? While stress isn’t typically the sole cause of atrial fibrillation (AFib), chronic stress can contribute to the development or worsening of arrhythmias by increasing heart rate and blood pressure. This may lead to more frequent or intense episodes. Similarly, excessive caffeine intake can sometimes act as a trigger for arrhythmias, though moderate consumption is generally safe. How can I reduce my risk of AFib? Like many cardiovascular conditions, the risk of atrial fibrillation (AFib) can be significantly lowered through healthy lifestyle choices. Managing common risk factors such as high blood pressure, high cholesterol, and diabetes is key. Eating a heart-healthy diet low in saturated fat and sodium, staying physically active, getting enough sleep, cutting out harmful activities like smoking and tobacco use, and reducing stress all play a role in prevention.
