Palpitations: What They Mean and When to See a Cardiologist

Palpitations are one of the most common reasons people seek medical advice from a cardiologist. They’re often described as a feeling that your heart is pounding, fluttering, skipping beats, or racing unexpectedly. While palpitations are usually harmless, they can sometimes be a sign of an underlying heart rhythm problem—or simply cause anxiety due to their sudden and uncomfortable nature.

If you're experiencing frequent or unexplained palpitations, it’s important to have them evaluated. Dr Li, a leading private cardiologist in London, offers expert assessment and personalised care to help you understand and manage your symptoms with confidence.

What Are Palpitations?

Palpitations are sensations that make you unusually aware of your heartbeat. You might feel like your heart is:

  • Racing or beating too fast

  • Skipping or adding extra beats

  • Fluttering or pounding in your chest or throat

  • Beating irregularly or unpredictably

Palpitations can occur at rest, during exercise, or even while lying down, and they may last just a few seconds or continue for longer periods.

Common Causes of Palpitations

Palpitations can be triggered by lifestyle factors or medical conditions, such as:

  • Stress or anxiety

  • Excessive caffeine, alcohol, or nicotine

  • Dehydration or fatigue

  • Thyroid problems

  • Certain medications or supplements

However, in some cases, palpitations may be a symptom of a heart rhythm disorder, such as:

When to See a Specialist

While occasional palpitations are usually nothing to worry about, you should consider seeing a cardiologist if you:

  • Experience frequent or long-lasting palpitations

  • Feel dizzy, breathless, or faint during episodes

  • Have chest pain or tightness

  • Have a history of heart conditions or arrhythmias

These could be signs of a more serious rhythm issue that deserves prompt medical attention.

Treatment Options

Treatment for palpitations depends on the cause. Dr Li offers a range of personalised options, including:

  • Lifestyle advice to manage triggers like stress, caffeine, or dehydration
