Atrial fibrillation (AFib) is the most common type of arrhythmia, affecting millions of people worldwide. Often described as a “quivering” or “irregular” heartbeat, AFib can significantly increase the risk of stroke, heart failure, and other complications if left untreated. At Korban Cardiology, we believe in empowering patients with knowledge to identify and manage this condition effectively.
What is Atrial Fibrillation?
In a healthy heart, electrical signals coordinate the steady contraction of the heart’s upper chambers (atria). In AFib, these signals become chaotic, causing the atria to beat irregularly or too quickly. This disrupts blood flow, increasing the likelihood of blood clots and other cardiovascular problems.
Signs and Symptoms of AFib
AFib can be tricky to detect because some individuals experience no symptoms. However, common signs include:
- Heart Palpitations: A noticeable fluttering or racing sensation in your chest.
- Fatigue: Feeling unusually tired, even after rest.
- Shortness of Breath: Difficulty breathing, particularly during physical activity or while lying down.
- Dizziness or Lightheadedness: Feeling faint or off-balance.
- Chest Discomfort: Tightness, pressure, or pain in the chest area.
If you experience any of these symptoms, especially if they appear suddenly or worsen over time, seek medical attention promptly.
Risk Factors for AFib
Several factors can increase your risk of developing AFib, including:
- Age: Risk increases significantly after age 65.
- High Blood Pressure: Uncontrolled hypertension can strain the heart and lead to AFib.
- Heart Disease: Conditions like coronary artery disease or heart failure are strongly linked to AFib.
- Sleep Apnea: This condition disrupts breathing during sleep, stressing the heart over time.
- Excessive Alcohol or Stimulant Use: Alcohol binge drinking or frequent use of stimulants can trigger irregular heart rhythms.
Why AFib is Dangerous
One of the most serious complications of AFib is stroke. Because blood flow in the atria is irregular, blood clots can form and travel to the brain, causing a blockage. In fact, individuals with AFib are five times more likely to suffer a stroke than those without the condition. Additionally, untreated AFib can weaken the heart over time, leading to heart failure.
Diagnosis and Treatment
At Korban Cardiology, we use advanced diagnostic tools like electrocardiograms (EKGs), Holter monitors, and echocardiograms to detect and evaluate AFib. Once diagnosed, treatment options may include:
- Medications: Blood thinners, antiarrhythmic drugs, or beta blockers may be prescribed to prevent blood clots, regulate heart rhythm, and control heart rate.
- Cardioversion: This procedure involves resetting the heart’s rhythm using electrical shocks or medication.
- Ablation Therapy: A minimally invasive procedure that targets and destroys areas of the heart causing abnormal electrical signals.
- Lifestyle Changes: Managing risk factors like high blood pressure, obesity, and sleep apnea can reduce the likelihood of AFib episodes.
- Surgical Options: In severe cases, surgical procedures like the Maze procedure may be recommended to create new pathways for electrical signals in the heart.
Living with AFib
While AFib is a chronic condition, many patients live full, active lives with the right management plan. Regular check-ups, lifestyle modifications, and adherence to prescribed treatments can dramatically reduce the risk of complications.
