Palpitations—the feeling that your heart is beating rapidly, forcefully, irregularly, or skipping a beat—can have several causes. These include lack of sleep, caffeine, stress, medication, and heart rhythm problems. The symptom alone does not show that someone is having a stroke.
Palpitations do not by themselves diagnose atrial fibrillation or stroke
Atrial fibrillation can increase the risk of blood clots and stroke in some people, but palpitations alone do not confirm atrial fibrillation. A clinician may need to assess the heart rhythm and other risk factors. Blood-thinning medicines have both benefits and risks, so do not start them on your own.
People with recurrent or longer-lasting palpitations, or a history of heart disease, should discuss the symptoms with a clinician. An electrocardiogram may be needed.
Know when to seek urgent help
Palpitations with chest pain, shortness of breath, dizziness, or fainting need urgent medical attention. Sudden facial drooping, arm weakness, or difficulty speaking can be signs of a stroke; seek emergency help.
What to note before an appointment
- When the episode began and how long it lasted
- Your pulse, if you were able to check it
- Medicines and caffeine consumed around that time
