Atrial Fibrillation Symptoms
AFib may or may not cause symptoms. If it does, atrial fibrillation symptoms may include the following:
- Quivering or fluttering heartbeat
- Irregular heartbeat
- Chest pain
- Fainting or confusion
- Shortness of breath
How Serious Is Atrial Fibrillation?
Some episodes of AFib resolve on their own. This is also called “spontaneous remission.” But since having AFib symptoms is uncertain, you may still want to monitor your heart and consult your doctor. Some cases of AFib also reveal an underlying condition such as an overactive thyroid, hypertension, diabetes, chronic lung disease or heart valve disease, which would need further treatment.
AFib is a serious condition that may lead to a stroke, heart failure, chronic fatigue, inconsistent blood supply and some other heart rhythm issues. Strokes caused by AFib tend to be more severe than strokes from other causes. This happens when a blood clot or plaque (fatty deposits) in the blood vessel lining block blood flow to the brain. AFib can become life-threatening when left untreated, so be sure to speak with a doctor as soon as you see signs and symptoms of AFib.
How Can You Reduce Your Risk for AFib?
Maintaining a healthy lifestyle is one of the best ways to reduce your risk for AFib. Eat a heart-healthy diet (avoid salt, saturated fats and high-cholesterol foods). Maintain a healthy weight and exercise regularly. Manage your blood pressure. Avoid smoking, recreational drugs, and limit your alcohol and caffeine intake. These things can help you keep your heart healthy and prevent other chronic conditions.
Atrial Fibrillation Treatment Options
Many people may not even be aware that they have AFib. Scheduling a heart screening can help our specialists evaluate and diagnose your condition and also offer a treatment plan to help lower your risks for serious complications. Treatments may include the following:
- Anticoagulants (e.g., warfarin, rivaroxaban, dabigatran, apixaban and edoxaban)
- Atrial fibrillation ablation
- Open-heart maze procedure to restore regular rhythm
Changes in lifestyle or medications for heart rate and rhythm, such as anticoagulants or blood thinners, may be prescribed to prevent blood clots or control heart rate. Cardioversion, another treatment option, may also be recommended to help get the heart back to a normal rhythm by delivering a jolt of electricity to the heart. However, if these efforts are unsuccessful, your doctor may recommend atrial fibrillation ablation or a surgical procedure to restore your regular heart rhythm.
Your health can’t wait. Understand your heart health to stay or track or make a plan. Safe care is available to evaluate for electrical issues of the heart such as AFib. Finding out and taking action can be life-saving.
What is Atrial Fibrillation Ablation?
Atrial fibrillation ablation involves threading a long, thin, flexible tube called a catheter into the heart through a blood vessel in the arm, upper thigh or neck. A specialist uses live X-ray images to carefully guide the catheter into the heart. Several flexible tubes with electrodes on the tips are run through the catheter and directed to make radiofrequency lesions designed to block the abnormal pathways of heart electricity.
What Happens During Atrial Fibrillation Ablation?
Patients are sedated during the procedure, but they may still feel some lightheadedness, rapid heartbeat, burning when any medications are injected, or chest discomfort due to energy application. An atrial fibrillation ablation procedure can last anywhere from four to nine hours. Following the procedure, pressure is applied to the site where the catheter was inserted, and patients must lie still for four to six hours. Their heart rate is closely monitored during this time.
How Effective Is Ablation for AFib?
The success rate of the first atrial fibrillation ablation is approximately 75% and will go up to 90% for the second procedure, if a second one is necessary. Atrial fibrillation ablation may be a more effective treatment than medications; however, as with any procedure, there are risks associated with atrial fibrillation ablation.
What Are the Surgical Options if Catheter Ablation is not Successful?
The Cox-MAZE III surgical procedure is an open heart operation where incisions and freezing lines are created on the atria to direct the electrical pathway of the heart into a normal rhythm for patients who have failed other less invasive modalities or are undergoing heart surgery for other reasons.
