Heart Palpitations
Introduction
Heart palpitations are a common experience where an individual feels that their heart is beating too hard, too fast, skipping a beat, or fluttering. Usually, palpitations are not serious, but they can sometimes be a symptom of a more significant health problem. This page offers a detailed overview of heart palpitations, including their definition, causes, and when to seek medical attention.
Definition of Heart Palpitations
Palpitations are the sensation of your heart beating in a way that is unusual for you, whether it’s faster, slower, or with an irregular rhythm. They can be felt in your chest, throat, or neck. Palpitations can be alarming, but they are often harmless and not a sign of a serious problem.

The causes of heart palpitations can range from everyday lifestyle factors to underlying medical conditions. They include:
Lifestyle Triggers:
- Stress, anxiety, or panic attacks: Emotional stress can trigger palpitations.

- Caffeine, nicotine, or alcohol: These substances can stimulate the heart.
- Medication: Some cold and cough medications, asthma inhalers, and beta-blockers can cause palpitations.
