Atrial Fibrillation (AFib)
Nearly 4 million people in the United States have atrial fibrillation (AFib). This heart rhythm abnormality can increase the chance of having a stroke and may lead to heart failure. The earlier AFib is treated, the better the chances are of staying in a “normal” heart rhythm.
What is atrial fibrillation (AFib)?
Atrial fibrillation is a rapid, irregular heartbeat in the top chambers of the heart. The atria “quiver” instead of contracting, increasing the chance of blood clot formation. At first, AFib starts and stops on its own. Over time, AFib progresses and controls the heart rhythm.
How can I know if I have AFib?
Usually when someone has AFib, their pulse is irregularly irregular (no pattern). Tests are needed to be 100% certain. Heart palpitations, racing, pounding, shortness of breath, weakness and lightheadedness are common. Tiredness, fatigue and a decreased ability to do household chores and exercise are also common.
What Increases the Risk of Having AFib?
- High blood pressure (# 1 cardiac cause)
- Sleep apnea (#1 non-cardiac cause)
- Smoking
- Being overweight
- Diabetes
- Heart failure
- Recent heart and lung disease or surgery
What can I do to reduce AFib triggers?
- Limit alcohol intake
- Avoid stimulants, like over the counter decongestants or recreational drugs
- Maintain a healthy body weight
- Do not smoke
- Limit your caffeine intake
- Avoid energy drinks entirely
- Reduce your stress level
What is the treatment for AFib?
There are several treatments for AFib. Sometimes, patients are given blood thinning medicine or a device to prevent blood clots and prevent stroke. A patient might also be given heart medicine to control the heart rate and help the heart stay in a normal rhythm. If further prevention is needed, a non-surgical procedure can be done called an ablation is done in the electrophysiology lab.
