How to Tell If You Have Atrial Fibrillation

Atrial fibrillation, commonly known as AFib, can be difficult to identify on your own. One of the primary signs is an irregular and often rapid heartbeat. For instance, your heart rate may exceed 100 beats per minute, and the rhythm may feel unpredictable, with beats that vary in strength and spacing. If you check your pulse and notice it's inconsistent, this could be a sign of AFib.

Common Symptoms of Atrial Fibrillation

Many individuals with AFib experience sensations such as fluttering in the chest, shortness of breath, fatigue, or dizziness. However, some people may not feel any noticeable symptoms at all, making it even more challenging to self-diagnose.

Accurate Diagnosis Through Medical Testing

Electrocardiogram (ECG) for AFib Detection

The most reliable method to diagnose atrial fibrillation is through an electrocardiogram (ECG). This non-invasive test records the electrical activity of the heart and can detect irregularities in heart rhythm. If symptoms are intermittent, a 24-hour Holter monitor or event recorder may be used to capture heart activity over a longer period.

When to See a Doctor

If you experience episodes of irregular heartbeat, especially if they occur frequently or are accompanied by dizziness, chest pain, or difficulty breathing, it's important to seek medical attention promptly. Early diagnosis and treatment can help prevent complications such as stroke or heart failure.

In cases where AFib occurs only occasionally, diagnosis can be more complex. Your doctor may recommend periodic monitoring or wearable heart rhythm trackers to catch any irregular episodes that happen sporadically.
