I recently took a pre-employment medical and the clinic doctor found the following:
"Early diastolic murmur, Grade I, heard at left 4th intercostal space, radiating to apex. Asymptomatic of unknown significance. Normal ECG. Also very faint late diastolic sound, suggestive of split S1. No previous family history. Blood pressure 120/70."
I am 29 and this is the first time I have had anyone tell me they heard a murmur. I have an echo scheduled although the results won't be available for sometime. Just curious what the possibilities are based on what the clinic doctor found. I follow a fairly intense cardio workout routine and have had no symptoms associated with exercise so far.
