What Is Atrial Fibrillation?
Atrial fibrillation, or AFib, is the most common type of irregular heartbeat — the heart’s upper chambers beat chaotically instead of in a steady rhythm. It doesn’t always cause noticeable symptoms, but left untreated, it significantly raises the risk of stroke and other complications.
Dr. Richa Sharma evaluates and manages AFib as part of her broader arrhythmia care, often using a Holter monitor to capture episodes that come and go.
Common Symptoms
A fluttering or racing heartbeat sensation (palpitations)
Fatigue or reduced exercise tolerance
Breathlessness
Occasionally, fainting or near-fainting episodes (syncope)
Why It Matters Beyond the Symptoms
AFib itself may feel manageable, but its real risk lies in how it affects blood flow — increasing the chance of clot formation, which can lead to stroke. This is why AFib is often screened for during a preventive heart check-up, even in people who feel largely fine.
FAQs
Can AFib come and go without me noticing?
Yes — this is called paroxysmal AFib, and it’s one reason extended monitoring like a Holter test is often more useful than a single in-clinic ECG.
Is AFib the same as a heart attack risk?
No, they’re different conditions, though both fall under cardiovascular disease. AFib’s main added risk is stroke, due to how it affects blood flow.
Can AFib be treated without surgery?
Many cases are managed with medication and lifestyle changes. Your specific treatment plan depends on the type and frequency of your AFib episodes.
