Looks at heart: An echocardiogram uses sound waves (sonar) to look at the structure and function of the heart. The strength of the heart muscle, size of the various heart chambers and the structure and function of the heart valves is determined. Damaged heart from a heart attack can be seen any any valves that are narrowed (stenosed) or leaky are easily seen.

SeeHeart & BloodFlow: Issues detectable by symptoms, stethoscope and/or ekg are limited; e.g. Most heart attacks & valve problems missed. Using us, 1-10 mhz, motion of the muscular chambers & blood flow become visible, measurements can be made & more issues evaluated. Us: safest of medical imaging techniques, yet quality very dependent on machine/tech/person/reader. Best always get video copies, read yourself & save.
