Heart murmurs, are caused by structural abnormalities of the heart, defective heart valves or holes in the walls of the heart...innocent heart murmurs, usually found in children, do not affect the patient s health and require no treatment. Heart murmurs due to septal defects may require surgery. Those due to valvular defects may require antibiotics to prevent infection during certain surgical or dental procedures, severely damaged valves can be repaired or replaced through surgery, two types for adults are diastolic (while relaxing) and systolic (during contraction of the heart muscle) some defects close on their own, others require surgery to prevent progressive damage to the heart, severe murmurs cause shortness of breath, dizziness, chest pains, palpitations, and lung congestion and if not treated can cause death...your heart does not skip a beat, you hear the vibrating and sloshing sounds made by turbulent blood flow in between the normal beats of your heart. You didn t say which kind of heart murmur you have or which tests your doctor has performed such as chest x-rays, an electrocardiogram and an echocardiogram to determine treatment. I suggest you ask your doctor about your concerns and questions you have.
