With your history, the ECG would show if there is any irregularity or evidence of coronary insufficiency to account for your murmur and the ultrasound would identify which valve was involved.
In a nutshell, is your heart murmur innocent as is probably the case OR is a valve not functioning, which valve, why and do you need treatment..................you probably wont.
they will wish to see which valve is leaking
( on the numbers game it is very likely to be MVR )
and whether it is serious ( ejection fraction)
it should be around 50%
miine is 35% so you can have a pretty crap ejection fraction and still be alive
Sqad as a student used to have to do all this wid just a stethscope. But as Hugh Leather once censor of the Royal College said - of the 35 whoops murmurs and clicks " look the victorians had nothng to do except listen to the heart and if THEY didnt hear it -it probably isnt really there"
but there is a book Aubrey Leatham
Auscultation of the Heart
you may wish to peruse
Innocent means that there is no structural damage to the heart or valves........it really hasn't been explained scientifically, but to me (sqad) it is the blood "sloshing" around the chambers of the heart and through the valves. Not very scientific......but they are the facts.
The shortness of breath may be due to many reasons...your'e getting fat, might be heart valve problems ....might be.....might be.....lets wait until the ECG and Ultrasound results are seen by a specialist.
// But if the murmur is not caused by a faulty valve, what could cause it ? .....What "innocent" cause in other words ?//
innocent - not associated with pathology ( = shortened life ) o jesus there used to be six i children of which embarassigly I can only recollect one - venous hum
