Atrial Fibrillation (AF): Out of rhythm, but not out of control. What Everybody Should Know
❤️🩹Atrial fibrillation is the most common heart rhythm disorder. It means the upper chambers of the heart (the atria) beat irregularly and often too fast. Instead of pumping blood smoothly, the heart rhythm becomes chaotic.
👉Why does atrial fibrillation matter?
- AF can reduce how efficiently the heart pumps blood.
- More importantly, it increases the risk of blood clots forming in the heart. These clots can travel to the brain and cause a stroke. People with AF have about a 5-fold higher risk of stroke compared to those without it.
🩺Common symptoms
Some people feel AF clearly, others not at all:
• Palpitations (feeling the heart racing or fluttering)
• Shortness of breath
• Fatigue or reduced exercise capacity
• Dizziness or chest discomfort
• Sometimes no symptoms – AF can be “silent”
💔Who is at risk?
AF becomes more common with age, but other factors play a role:
• High blood pressure
• Heart disease or heart failure
• Diabetes
• Obesity and sleep apnea
• Excess alcohol intake
• Thyroid disorders
💊 How is AF treated?
Treatment depends on symptoms and individual risk, but usually focuses on three key goals:
1. Stroke prevention – often with blood thinners (anticoagulants)
2. Heart rate control – slowing the heart rate
3. Heart rhythm control – restoring or maintaining a normal rhythm (medication or procedures like ablation)
Early diagnosis and proper treatment can significantly reduce complications and improve quality of life.
🗝️Key message:
An irregular heartbeat is not something to ignore. Detecting atrial fibrillation early can be lifesaving.
