You did good. I teach my students to listen. The U turn at the throat is the arch of the aorta. Sound is different there. I am not familiar with those sounds. Doppler fast Fourier analysis makes the sound, the rest is magic. Looks like you had a good tech.
You are right; If it was serious you would be in the hospital.
Let's start planning the North Carolina Joey Rocket Run .
STOP Smoking and STOP drinking Dr. Pepper!!!!!!!!!!!!!!! Drink red wine Can't walk - like 1K9 said, start with short walk.... stay consistent with it. consistency is better that high intensity/long endurance for you at this point No fatty foods - You'll learn to adapt with healthy foods, grille, use lots of herbs & spices for flavor. After a while you won't miss fatty foods. 2 yrs...no riding m/c - do what it takes to work your way back to it 10 yrs...no sex - LOOK AT ALL THE MONEY YOU'LL SAVE!!!!!!
Good news! Hang in there & treat the problems per the Dr's orders
