Ecocardiogram is also pretty good - they rub probe around on your chest and a picture of your heart will come up on a screen - will show how it works or is working. Drs could tell I had problem just by listening to my heart with stethoscope
Starting to see a cardiologist by 35 is good idea - Lord blessed me by letting me have a reason to go to dr or I would never had sense enough to go and my time would hav come a long time ago. Now a heart dr listens to my heart 1/year and I get an eco about every 3 years - i hav a pig valve n my heart
