Heart palpitations are typically harmless and may go away without any interventions or treatments. In the event that there is an underlying cause of the heart palpitations, your doctor will suggest changing the behaviors that initiate the palpitations. In some cases, beta-blockers or calcium-channel blockers are administered if lifestyle changes fail to prevent heart palpitations. If an underlying medical condition is causing the heart palpitations, the underlying condition is treated. When your doctor is unable to cure your heart palpitations, you may be referred to a heart rhythm specialist (electrophysiologist) for treatments.
