Often palpitations are innocent, but they can also be of moderate importance or represent an extremely dangerous situation.  Because of the potential for a serious problem to result from a 'palpitation', all patients who experience this sensation should consult their GP.  In some patients, a referral to a cardiologist is required for investigation and possible treatment of the underlying issue.

Investigations often include blood tests, an echocardiogram (heart scan), a 24 hour Holter monitor and an exercise treadmill test.  Some patients require more extensive investigations.  Treatments range from reassurance through various medicines and even ablative therapy:  a therapeutic 'burn' on the inside of the heart to "cut" an unwanted electrical circuit, or an implantable defibrillator device:  for the very occasional patient with very serious electrical problems.
