Palpitations Understanding heart palpitations

Heart palpitations are a sensation of the heartbeat. This may feel like heart racing, heart fluttering, pounding, skipping, or irregular beats.

Palpitations are common and, in many cases, are not caused by serious heart disease. They may occur in healthy individuals and can be triggered by stress, caffeine, hormonal change, illness, or fatigue.

However, in some situations, palpitations may reflect an underlying heart rhythm disturbance. The role of assessment is to determine whether symptoms are benign or require further management.

What heart racing or fluttering can mean

Heart racing may occur during anxiety, exertion, fever, dehydration, or hormonal fluctuation. Heart fluttering can sometimes represent extra beats or brief rhythm changes that are often harmless.

Less commonly, palpitations may be related to sustained rhythm disturbances such as supraventricular tachycardia or atrial fibrillation. These conditions may require specific treatment.

Key features that guide assessment include:

  • How suddenly symptoms start and stop
  • How long episodes last
  • Whether there is associated dizziness, chest discomfort, or breathlessness
  • Frequency and pattern of episodes
  • Family history of rhythm disorders

Most palpitations are intermittent and not dangerous. Careful history often provides as much information as testing.

How palpitations are assessed

Assessment begins with a detailed discussion of symptoms and triggers. A resting ECG may be performed to evaluate the baseline rhythm.

Because many rhythm disturbances are intermittent, ambulatory monitoring is often useful. This may involve a Holter monitor worn for 24 to 48 hours or extended monitoring for 1 to 2 weeks. These devices help correlate symptoms with heart rhythm.

Testing is selected to answer a specific clinical question rather than performed routinely. In many cases, results are normal and provide reassurance.

When to seek assessment

Cardiac review may be appropriate if heart palpitations are:

  • Persistent or worsening
  • Associated with dizziness or fainting
  • Accompanied by chest discomfort or breathlessness
  • Occurring in the context of known heart disease

If symptoms are severe or accompanied by collapse, urgent medical attention is required.

For many people, however, palpitations are benign and can be managed with education and simple lifestyle adjustments.

Management and next steps

Management depends on the cause identified. Some rhythm disturbances require medication or procedural treatment, while others require only reassurance and monitoring.

Lifestyle factors such as sleep, hydration, caffeine intake, and stress can influence heart racing and fluttering. Addressing these may significantly reduce symptom burden.

The goal of assessment is clarity. Understanding what symptoms represent often reduces anxiety and allows people to return to normal activity with confidence.

Frequently Asked Questions

Heart palpitations can be caused by stress, caffeine, dehydration, hormonal changes, illness, or heart rhythm disturbances. Many causes are benign.

Heart racing is not always dangerous. It depends on the cause, duration, and associated symptoms. Assessment helps determine whether further treatment is needed.

Heart fluttering is often described as a brief, rapid or irregular sensation in the chest. It may represent extra beats or short rhythm changes.

Palpitations should be assessed if they are persistent, worsening, associated with fainting, or occur alongside chest pain or breathlessness.

Diagnosis may involve clinical history, ECG testing, and ambulatory monitoring, such as a Holter monitor to capture intermittent rhythm changes.

Anxiety can trigger palpitations or heart racing. However, symptoms should be assessed to exclude underlying rhythm disorders before attributing them solely to anxiety.
