Palpitations are the feeling that your heart is racing, fluttering, pounding, or skipping a beat. After you have been diagnosed with a heart condition, you may notice these sensations from time to time. Most are harmless, but some need attention.
Key facts
- Palpitations are common and often harmless, but they can also signal a change in your heart rhythm.
- Keeping a record of when they happen can help your healthcare team find the cause.
- Treatments include lifestyle changes and medical procedures, but never stop or change your prescribed treatment without talking to your doctor.
Yes, many people with heart conditions experience palpitations at some point.
Anyone with a heart condition, regardless of age or how long ago the diagnosis was made. They can also occur in people without known heart problems.

- Physical activity
- Changes in your heart rhythm (like atrial fibrillation)
- Side effects of some medications or supplements (ask your doctor or pharmacist)

- Family history of heart rhythm problems
When to see a doctor
See a doctor urgently if:
- See a doctor the same day if your palpitations become more frequent, last longer, or come with new symptoms like dizziness, light-headedness, or a feeling of heaviness in your chest.
Book a routine appointment if:
- Discuss any new or worsening palpitations at your next scheduled appointment. Bring a note of when they occur, what you were doing, and any other symptoms.
Diagnosis
Your doctor will listen to your symptoms, review your medical history, and may order tests to see how your heart is beating.
Tests that may be done
- Electrocardiogram (ECG or EKG) — a quick recording of your heart’s electrical activity
- Holter monitor — a portable device you wear for a day or two to record your heart rhythm during daily life
- Event monitor — a device you press to record your heart rhythm when you feel palpitations
- Echocardiogram — an ultrasound to look at your heart’s structure and function
- Blood tests — to check for anaemia, thyroid problems, or electrolyte imbalances
What to expect at your appointment
You may not need all tests. Most are painless and can be done in an outpatient clinic. Your care team will explain each step. It may take time, but getting a clear picture of your heart rhythm is key to a safe plan.
Treatment
Treatment depends on the cause and whether the palpitations are linked to a serious rhythm problem. The goal is to reduce symptoms and lower any risk to your heart.
Self-care at home
- Keep a diary of your palpitations — note the time, what you were doing, and how you felt
- Limit caffeine, alcohol, and nicotine
- Get enough sleep and manage stress with techniques like breathing exercises or gentle movement
- Stay well hydrated by drinking water (unless your doctor tells you otherwise)
- Take any prescribed heart medications exactly as directed — never stop them on your own
Medical treatments
Your healthcare provider may suggest medicines to control your heart rate or rhythm (only after a full evaluation). In some cases, a small device called a pacemaker can help regulate the heartbeat, or a cardiologist may perform a procedure to correct an abnormal rhythm. The choice is always tailored to your specific condition and preferences.
When is surgery considered?
Surgery is rarely the first choice, but it may be considered if palpitations are caused by a structural heart problem (like a faulty valve) and other options have not worked.
Living with this condition
You can live a full, active life with palpitations. The key is to know your usual pattern and check in with your healthcare team if anything changes. Most days are normal — and you can do most activities safely.
Lifestyle tips
- Build a consistent sleep routine
- Moderate exercise, such as brisk walks, is usually safe — but ask your doctor what level is right for you
- Practice relaxation exercises when you feel stressed or anxious
- Avoid heavy binge drinking or very high doses of caffeine
- Wear a medical alert bracelet if you have a known serious rhythm condition (ask your doctor if this applies)
Diet and exercise
A heart-healthy diet rich in vegetables, whole grains, lean proteins, and healthy fats supports your heart. Limit salty foods and sweets. For exercise, aim for at least 150 minutes of moderate activity per week, as approved by your care team. Stop and rest if you feel chest pain, severe breathlessness, or faintness.
Mental health and emotional wellbeing
Palpitations can make you feel anxious or afraid. Anxiety can also make palpitations worse, creating a cycle. It is common to worry, and it is okay to feel that way. Talking to a counsellor or a trusted friend can help. Remember that your symptoms are real and your care team takes them seriously.
Prevention
Not all palpitations can be prevented, especially if they are linked to a heart rhythm condition. But you can reduce how often they happen by avoiding triggers like excess caffeine, staying active, and following your treatment plan.
Vaccines
Keep up to date with recommended vaccines, such as flu and pneumonia shots, because infections can put extra stress on your heart.
Screening programmes
Routine check-ups with your healthcare provider help catch changes early. If you have a known heart condition, your follow-up appointments are your best screening.
Complications
If left untreated
- Risk of fainting or falling, which can cause injuries
- If the underlying rhythm problem is serious, it may increase the risk of stroke or heart failure
- Anxiety and reduced quality of life due to worries about the heart
Long-term outlook
Most people with palpitations after a heart diagnosis do very well. Many find that with the right treatment, support, and lifestyle adjustments, symptoms lessen or become easier to manage. Your healthcare team is there to help you live a long and active life.
