What can trigger atrial fibrillation?

As a medical professional with expertise in cardiology, I can provide you with a detailed explanation of what can trigger atrial fibrillation (AFib). Atrial fibrillation is a common heart rhythm disorder that can be caused by a variety of factors. Here are some of the most common triggers: 1. Heart Disease: Conditions such as coronary artery disease, heart failure, and valvular heart disease can increase the risk of developing AFib. 2. High Blood Pressure (Hypertension): This is one of the most significant risk factors for AFib. 3. Sleep Apnea: This sleep disorder can disrupt breathing during sleep and has been linked to AFib. 4. Alcohol Consumption: Excessive alcohol intake, particularly binge drinking, can trigger episodes of AFib. 5. Obesity: Being overweight or obese can increase the likelihood of developing this heart condition. 6. Diabetes: This chronic condition can lead to various heart problems, including AFib. 7. Thyroid Disease: An overactive thyroid (hyperthyroidism) can cause AFib. 8. Congenital Heart Disease: People born with heart defects are at a higher risk of developing AFib. 9. Electrolyte Imbalances: Imbalances in the body's levels of potassium, calcium, or magnesium can lead to AFib. 10. Stress and Anxiety: These can trigger AFib in some individuals, particularly if they have an underlying predisposition to the condition. It's important to note that AFib can also occur without any identifiable cause, and it may be the first sign of an underlying heart problem.
