The description of your medical condition referring to heart valves is considered medically insignificant and may not progress or cause symptoms. An EF of 60 is good, and it represents the percent of blood pumped with each heartbeat (normal is 50 to 70%)
For your doctor to make a diagnosis regarding a heart rhythm disorder may require an EKG test. The test involves monitoring and recording the electrical impulses as it passes thru the heart.
With a 60% EF there should not be any shortness of breath due to a heart issue. But if there is a heart problem causing shortness of breath it can be due to the heart is not receiving sufficient blood from the lungs as the right side has a problem pumping blood to the lungs, Under that condition the 60% is irrelevant because the cardiac output is low. There can be a medical problem that causes low oxygen levels in the blood such anemia, etc.
Any advice should be based on your health history, concomitant health issues, medication, etc, and your treating doctor should have good information that can help you.
