PalpitationsCook Children's


Palpitations, or heart palpitations, are rapid or irregular heartbeats that feel like the heart is racing or fluttering.

Lots of things can cause the heart to beat quickly, including exercise, stress, fever, caffeine, nicotine, illegal drugs, thyroid disorders and certain medications. This can trigger palpitations, which are fluttering heartbeats — the feeling that the heart has skipped a beat or is beating irregularly. In most cases, these types of palpitations are harmless.

Frequent palpitations or palpitations that occur with fainting, chest pain, sweating, shortness of breath, weakness, turning pale or nausea might indicate an arrhythmia and your child should be referred to a pediatric cardiologist for evaluation.

Most palpitations won't require any treatment. If an arrhythmia is causing the palpitations, treating its cause usually will stop the palpitations. Palpitations occurring repeatedly or with other associated symptoms should be evaluated by a doctor.
