People describe palpitations in different ways, but common experiences include:

• A racing heartbeat, even at rest.
• Fluttering or a feeling that the heart is “flip‑flopping.”
• Skipped beats or sudden strong thumps in the chest.
• A rapid, irregular rhythm that comes in bursts or lasts minutes to hours.
• Associated symptoms such as dizziness, breathlessness, chest discomfort, or fatigue.

These sensations may occur during exercise, stress, caffeine intake, or without any clear trigger.

Heart‑related palpitations arise when the electrical system of the heart is disrupted or when the heart muscle is under strain.

• Coronary artery disease can reduce blood flow to the heart muscle, making abnormal rhythms more likely.
• Heart failure can stretch or stiffen the heart, affecting its electrical pathways.
• Valve disease may cause the heart to work harder, triggering irregular beats.
• Atrial fibrillation, one of the most common rhythm disorders, causes an irregular and often rapid heartbeat that many people feel as palpitations.
• Ventricular arrhythmias, though less common, can be more serious and require urgent evaluation.

Not all palpitations are due to heart disease—stress, caffeine, alcohol, thyroid problems, and some medications can also play a role—but distinguishing the cause is important.

Immediate medical attention is important if palpitations are:

• Accompanied by chest pain, fainting, severe breathlessness, or collapse.
• Lasting longer than a few minutes with significant symptoms.
• Occurring in someone with known heart disease.

Even milder palpitations that are new, frequent, or interfering with daily life should be discussed with a clinician, as early assessment can identify treatable causes.

Several lifestyle measures help reduce the likelihood of palpitations linked to heart disease:

• Regular physical activity suited to one’s health.
• A balanced diet low in excess salt, sugar, and unhealthy fats.
• Avoiding smoking and moderating alcohol and caffeine.
• Managing blood pressure, cholesterol, and diabetes.
• Regular check‑ups, especially for people with a family history of heart rhythm problems.

Understanding palpitations and recognising when they may be heart‑related helps people act early and confidently. Are you looking to include this in a broader set of public‑facing heart health materials?
