Atrial Fibrillation (AFib): Understanding This Common Heart Rhythm Disorder
Atrial fibrillation (AFib) is a prevalentable type of heart arrhythmia characterized by an abnormal or irregular heartbeat. Patients often describe AFib as a quivering or fluttering sensation in their chest, indicative of the heart's upper chambers beating chaotically. If you're experiencing potential AFib symptoms, don't delay seeking cardiovascular care.

What Triggers AFib? Identifying Causes and Risk Factors
AFib occurs when the heart's electrical system is disrupted, leading to an irregular heartbeat. Several conditions and lifestyle choices can contribute to this electrical dysfunction and increase your likelihood of developing AFib.
Key Causes of AFib Related to Heart Conditions
Damage to the heart, which can trigger AFib, is often associated with pre-existing cardiovascular issues. These include:
- Coronary Artery Disease: Narrowing of the heart's arteries.
- Heart Attack: Damage to the heart muscle from blocked blood flow.
- Heart Valve Disease: Issues with the heart's valves that regulate blood flow.
- High Blood Pressure (Hypertension): Chronically elevated blood pressure puts strain on the heart.
- Congenital Heart Defects: Heart abnormalities present at birth.
Additional Risk Factors for AFib
Beyond direct heart issues, other factors can significantly raise your risk, including:
- Alcohol Abuse: Excessive alcohol consumption can disrupt heart rhythm.
- Family History of AFib: Genetic predisposition plays a role.
- Obesity: Being overweight or obese increases cardiovascular strain.
- Advanced Age: The risk of AFib increases significantly with age.
- Certain Medical Conditions:
- Chronic Lung Disease: Conditions like COPD can strain the heart.
- Diabetes: Poorly managed blood sugar levels can damage blood vessels and nerves.
- Sleep Apnea: Interrupted breathing during sleep puts stress on the heart.
- Thyroid Disease: Particularly an overactive thyroid (hyperthyroidism).
Understanding these AFib causes and risk factors is crucial for prevention and effective management. If you have concerns about your risk, consult with a cardiac specialist.
Understanding AFib Symptoms
It's important to know that AFib symptoms can vary greatly among individuals. Some people with AFib may experience no noticeable signs at all, with the condition only being detected during a routine medical examination.
Types of Atrial Fibrillation Based on Symptom Pattern
AFib is categorized by how often symptoms occur, and their response to treatment.
- Occasional (Paroxysmal) AFib: Symptoms come and go, often resolving on their own within minutes to hours.
- Persistent AFib: This form of irregular heartbeat does not go away without medical intervention. Treatment is necessary to help restore and maintain a normal heart rhythm.
- Permanent AFib: In this stage, a normal heart rhythm cannot be restored. However, effective AFib management focuses on controlling your heart rate to significantly reduce possible complications like stroke.
Diagnosing AFib
Accurate AFib diagnosis is crucial for effective treatment. Your doctor will assess your medical and health history, conduct a comprehensive physical exam, and evaluate your individual risk factors. To confirm the presence of an irregular heartbeat, common diagnostic tests for AFib include:
- Echocardiogram: Uses sound waves to create images of your heart's structure and function.
- Electrocardiogram (EKG/ECG): Records the electrical activity of your heart.
- Holter Monitor: A portable device worn for 24 to 48 hours (or longer) to record heart activity during your daily routine.
- Stress Testing: Evaluates heart function during physical exertion.
Comprehensive AFib Treatment Options
The primary goals of AFib treatment are to control your heart rate, restore a normal heart rhythm when possible, and significantly reduce the risk of serious complications like blood clots and stroke. Your personalized treatment plan may involve various approaches aimed at resetting your heart's rhythm, such as:
Catheter Ablation
Targeting and destroying small areas of heart tissue responsible for abnormal electrical signals, helping to correct the irregular heartbeats.
Maze Procedure
An advanced surgical procedure that creates a specific pattern of scar tissue to interrupt chaotic electrical pathways in the atria.
Pulsed Field Ablation (PFA)
PFA is a new, non-thermal catheter ablation technique is used to treat AFib by using electrical pulses to target and eliminate the abnormal heart tissue causing the irregular heartbeat, offering a potentially safer and more efficient alternative to traditional thermal ablation methods.
Watchman Procedure
An innovative implant designed to close off the left atrial appendage, significantly reducing AFib stroke risk without long-term blood thinners for eligible patients.
Identifying the best treatment option for AFib requires a thorough evaluation by a cardiac specialist. We encourage you to consult with a specialized cardiologist or heart surgeon at Dignity Health, St Rose Dominican Hospital to discuss your condition and tailor a treatment strategy that's right for you.
