Atrial Fibrillation vs Premature Beats: Understanding the Symptom Differences

Atrial fibrillation (AFib) and premature beats share several overlapping symptoms, such as palpitations or a noticeable pause in the heartbeat. Patients with either condition may also experience chest tightness or discomfort. However, AFib often presents with more severe symptoms, especially during the initial episodes. These may include a rapid heartbeat, repeated sensations of fluttering in the chest, trembling hands, sweating, shortness of breath, and even nausea.

Key Symptom Differences

One of the hallmark symptoms of premature beats is the distinct feeling of the heart "skipping a beat." This occurs because after an early heartbeat, the heart resets its rhythm, leading to a brief pause that patients often notice. While this sensation is common with premature beats, some AFib patients may also feel similar pauses, particularly when long intervals occur between heartbeats.

When to Seek Medical Evaluation

If symptoms are confusing or difficult to distinguish, it's crucial for patients to undergo an electrocardiogram (ECG) to accurately diagnose the underlying condition. Proper identification of AFib or premature beats is essential for effective treatment and management. If you experience persistent or worsening symptoms, consult a healthcare professional for a thorough evaluation.
