How common is palpitations in generalised anxiety disorder?

Anxiety-related palpitations may occur with trembling, sweating, rapid breathing, muscle tension, stomach upset or difficulty sleeping. They can feel frightening even when the rhythm is normal. Caffeine, nicotine, decongestants, thyroid problems, anaemia and heart rhythm conditions can also cause palpitations, so a new symptom should not automatically be attributed to anxiety.

A clinician may ask about the pattern, worry symptoms, medicines and stimulants, and may examine you or arrange a heart tracing when appropriate. Mental health support can help reduce the cycle of worry and body monitoring.

Arrange a review if episodes keep returning, disturb sleep or lead you to avoid normal activities. During an episode, sit safely, loosen tight clothing and breathe slowly with a comfortable longer exhalation. Reduce caffeine and nicotine if they trigger symptoms. Psychological therapy, prescribed treatment and practical anxiety strategies can be discussed with a clinician.

Seek emergency care for palpitations with chest pain, severe breathlessness, fainting, new confusion or a sudden one-sided weakness. Get prompt medical advice when the heartbeat is persistently very fast or irregular, starts during exertion, or is unlike previous anxiety episodes. If anxiety brings thoughts of self-harm, seek immediate crisis support or emergency help.

Ask how anxiety and heart causes can be distinguished, whether a heart tracing is appropriate, which treatments may help, and what symptoms should trigger urgent care.
