What is Afib?
Atrial fibrillation (Afib) is a common heart condition characterized by an irregular and often rapid heartbeat. Atrial fibrillation is a manageable condition with proper diagnosis, treatment, and lifestyle adjustments. Early detection and proactive management can significantly improve outcomes and quality of life for those affected.
September is Afib Awareness Month; we invite you to take a moment to learn more from Jennifer Law, Cardiology Nurse Practitioner with Centennial Heart at Horizon.
What is Atrial Fibrillation?
1. Afib is a type of arrhythmia (irregular heartbeat) that can lead to stroke, heart failure, and other heart-related complications.
2. Common causes include high blood pressure, heart valve disease, coronary artery disease, and other heart conditions. Lifestyle factors such as obesity, excessive alcohol consumption, and stress can also contribute.
3. Many people with Afib experience symptoms like palpitations, shortness of breath, fatigue, dizziness, or chest pain. However, some may be asymptomatic.
Risk Factors
1. Age - The risk of developing Afib increases with age, particularly in individuals over 65.
2. Other Health Conditions - Conditions such as hypertension, diabetes, and thyroid problems can increase the risk of Afib.
3. Family History - A family history of Afib can also elevate a person's risk.
Diagnosis
1. Electrocardiogram (EKG) - The primary tool used to diagnose Afib is an ECG, which records the electrical activity of the heart.
2. Heart Monitor - This portable ECG device can monitor the heart’s rhythm over 24-48 hours to detect intermittent Afib.
3. Echocardiogram - This ultrasound test helps in assessing heart structure and function, which can provide insights into the underlying causes of Afib.
Treatment Options
1. Medications - Anticoagulants (blood thinners) are often prescribed to reduce the risk of stroke. Rate or rhythm control medications may also be used to manage heart rate and restore normal rhythm.
2. Lifestyle Changes - Weight management, regular exercise, a heart-healthy diet, and limiting alcohol and caffeine can help manage Afib symptoms.
3. Procedures - In some cases, procedures like electrical cardioversion, catheter ablation, or surgery may be necessary to restore normal heart rhythm.
