What are the triggers for atrial fibrillation?

As a medical professional with expertise in cardiology, I can provide you with information on the triggers for atrial fibrillation (AFib). Atrial fibrillation is a common heart rhythm disorder characterized by irregular and often rapid heart rates. There are several factors that can trigger or exacerbate AFib, including: 1. Alcohol consumption: Drinking alcohol, particularly in excess, can trigger AFib in some individuals. 2. Caffeine: High levels of caffeine can also act as a trigger for some people. 3. Stress and anxiety: Emotional or physical stress can lead to an episode of AFib. 4. Obesity: Excess weight can put pressure on the heart and increase the risk of developing AFib. 5. Sleep apnea: This sleep disorder can cause pauses in breathing during sleep, which may trigger AFib. 6. High blood pressure: Also known as hypertension, it's a significant risk factor for developing AFib. 7. Heart-related conditions: Conditions such as heart failure, coronary artery disease, and valvular heart disease can increase the risk of AFib. 8. Thyroid problems: An overactive thyroid (hyperthyroidism) can cause AFib. 9. Physical exertion: Intense exercise can sometimes trigger AFib, especially in those with underlying heart conditions. 10. Certain medications: Some medications, including certain asthma medications and stimulants, can trigger AFib. It's important to note that not all individuals with AFib will have the same triggers, and some may not have any identifiable triggers at all. Treatment often involves managing these triggers and may include lifestyle changes, medications, or procedures to regulate the heart rhythm.

Atrial fibrillation (AFib) is a medical disorder that affects the upper chambers, known as atria, of the heart. People with AFib experience irregular heartbeats caused by abnormal electrical signals in the atria. ... Many people who have paroxysmal AFib experience transient episodes brought on by a specific trigger.
