Atrial Fibrillation: Understanding the Most Common Arrhythmia
Atrial fibrillation (AFib) is the most common type of abnormal heart rhythm, affecting millions worldwide and significantly increasing stroke risk.
What is Atrial Fibrillation?
In AFib, the electrical signals in the atria become chaotic. Instead of contracting in a coordinated manner, the atria quiver irregularly, causing the ventricles to beat irregularly and often too fast.
Why AFib is Dangerous
Stroke: AFib increases stroke risk five-fold because blood can pool and form clots.
Heart Failure: The rapid, irregular heartbeat can weaken the heart over time.
Reduced Quality of Life: Symptoms can significantly impact daily activities.
Treatment Approach
AFib treatment has three main goals:
- Rate Control: Slowing the heart rate to a normal range
- Rhythm Control: Restoring and maintaining normal rhythm
- Stroke Prevention: The most critical aspect—anticoagulants reduce stroke risk
Living with AFib
Many people with AFib lead full, active lives:
- Take medications exactly as prescribed, especially blood thinners
- Maintain healthy weight and exercise regularly
- Limit alcohol and manage caffeine intake
- Know the warning signs of stroke (FAST: Face drooping, Arm weakness, Speech difficulty, Time to call emergency)
"Kahit irregular ang tibok, hindi kailangan irregular ang buhay." (Even if the heartbeat is irregular, life doesn't have to be.)
