Palpitation is commonly attributed to stress, alcohol, tobacco, caffeine and certain medicines. Elimination of these might help in recurrence. Thyroid problems are the culprit, sometimes, and removal of the thyroid problem helps. At times, palpitations call for an electric shock or cardiac defibrillation.
