Ideopathic hypertrophic subaortic stenosis
Even though the sound of it is something quite atrocious.
If you hear the murmur you can make the diagnosis:
Ideopathic hypertrophic subaortic stenosis!
My father the doctor sang this sometimes. He described it as meaning, from the greek:
Ideopathic - We have no idea why it's doing this
hypertrophic - overgrown/overfed muscle
subaortic - below the aorta
stenosis - swelling that squeezes off a blood vessel.
