Symptoms and Causes of Atrial Fibrillation

Atrial fibrillation is characterized by an irregular and often rapid heart rate that can lead to poor blood flow. Dr. Dale Adler, MD, explains that changes in heart geometry and function, such as mechanical stretching of the heart chambers, can predispose individuals to atrial fibrillation. Recognizing symptoms like palpitations, fatigue, and shortness of breath is crucial for early diagnosis and management.

Lifestyle Management for Atrial Fibrillation Prevention

Dr. Dale Adler, MD, emphasizes the importance of maintaining a healthy heart to prevent atrial fibrillation. Key strategies include controlling blood pressure, managing diabetes, and maintaining a healthy weight. These measures help reduce the stretch in the heart's upper chambers, decreasing the risk of anatomical changes that lead to atrial fibrillation.

Medication Options for Atrial Fibrillation

For patients with atrial fibrillation, Dr. Dale Adler, MD, discusses the use of oral anticoagulants to prevent stroke and medications to control heart rate. While antiarrhythmic medications can be effective, they must be used cautiously, especially in patients with structural heart disease or coronary artery issues. Dr. Adler advises that these medications are worth trying under careful medical supervision.

Pulmonary Vein Isolation Procedure

Dr. Dale Adler, MD, describes pulmonary vein isolation as a highly effective treatment for atrial fibrillation. This procedure involves inserting catheters into the pulmonary vein to disconnect electrical triggers from the heart. With an 80% to 90% success rate, pulmonary vein isolation can potentially cure atrial fibrillation, although some patients may require a second procedure within months of the first.

Importance of a Second Opinion

Dr. Anton Titov, MD, highlights the value of seeking a second opinion to ensure a correct and complete atrial fibrillation diagnosis. A second opinion can also help patients choose the best treatment strategy, providing confidence in their care plan. Dr. Dale Adler, MD, supports this approach, particularly for complex cases like paroxysmal atrial fibrillation.

Dr. Anton Titov, MD: How to prevent atrial fibrillation? Treatment of atrial fibrillation by pulmonary vein isolation. Second opinion ensures that atrial fibrillation diagnosis is correct and complete. Second opinion also helps to choose the best treatment strategy for atrial fibrillation. Seek second opinion on paroxysmal atrial fibrillation and be confident that your treatment is the best. New oral anticoagulants in AFib treatment.

Dr. Anton Titov, MD: Prevention of atrial fibrillation is based on trigger and substrate reduction. Mechanical stretching of heart chambers predisposes to AFib. Paroxysmal atrial fibrillation can signify transition to permanent cardiac arrhythmia.

Dr. Dale Adler, MD: The prevention of atrial fibrillation is really in having a healthy heart. To prevent atrial fibrillation, patients need to control blood pressure very well. Patients need to control diabetes very well. Patients need to control weight very well. This should reduce the amount of stretch in the top chamber of the heart. This will reduce the risk of anatomical change that leads to atrial fibrillation.

Dr. Dale Adler, MD: What else can you do to treat atrial fibrillation? As we discussed, we put patients on oral anticoagulant medications. We also use medications to slow down their heart rate. But in those patients who still have atrial fibrillation, we favor the use of antiarrhythmic medications.

Dr. Dale Adler, MD: We do not really like to use antiarrhythmic medications in the long term. Sometimes you are trying to alter the heart's rhythm, then you usually can make the rhythm worse potentially instead of better. But antiarrhythmic medications are worth a try. Antiarrhythmic medications in patients with atrial fibrillation have to be used cautiously.

Dr. Dale Adler, MD: There are patients who have structural heart disease. There are also patients who have problems with coronary arteries that supply blood to the heart. Antiarrhythmic medications may be okay in such patients. The heart is getting plenty of blood flow. But using antiarrhythmic medications may not be okay when a patient is not getting enough blood flow to the heart.

Dr. Dale Adler, MD: But after taking all precautions, we usually feel that antiarrhythmic medicine in a patient with atrial fibrillation may be used. It is useful to try for a period of time. Sometimes antiarrhythmic medicines do not work well in a patient with atrial fibrillation. Then we can do a treatment procedure called "pulmonary vein isolation". This treatment method can be very effective.

Dr. Dale Adler, MD: "Pulmonary vein isolation" for atrial fibrillation works like this. Catheters are inserted into the pulmonary vein. There is an attempt to disconnect from the rest of the heart those electric triggers that come from the pulmonary vein. Patients who consider pulmonary vein isolation for atrial fibrillation might need to repeat this procedure a second time. It is repeated within the first several months of the first pulmonary vein isolation for atrial fibrillation.

Dr. Dale Adler, MD: But there is an 80% to 90% probability that pulmonary vein isolation will permanently cure atrial fibrillation.

Dr. Anton Titov, MD: Cure can happen in those who agree to do pulmonary vein isolation. Atrial fibrillation prevention and treatment. How to reduce changes in heart that cause AFib. Antiarrhythmic drug therapy and pulmonary vein isolation.
