The treatment depends on what's causing the condition:
Side effects depend on the treatment used. Heart medications used to quiet the palpitations can cause worsening of the palpitations, life-threatening arrhythmias, swelling, severe allergic reactions, fatigue, dizziness, headache, and depression.
Simple, intermittent palpitations require no treatment and have no long-term consequences. If the palpitations continue, then long-term follow-up is required. If the underlying disease is curable and the palpitations go away, no further treatment may be needed.
The person monitors the frequency of palpitations. Any irregularity lasting longer than a few minutes should be evaluated immediately by a healthcare provider. Medical help should be sought immediately if the person has chest pain, shortness of breath, excessive sweating, dizziness, or fainting. Regular visits to the healthcare provider to adjust heart medications may be required. Changes in the pattern, intensity, or duration of palpitations should be reported to the healthcare provider right away.
