Besides many other noninvasive and blood-related tests, perhaps the most informative test is the “echocardiography”.
In echocardiography, our patient lies in a special side-lying position, we apply a jelly-like material to the heart area of the front chest, to certain points. Then from device through a long cable network, an image form from the sound waves that emit a sound; and reflection return from those sound waves, just like radar systems. We send sound waves to the heart by applying that jelly with long reflective equipment device and we call this “probe”.
This sound passes through the atria, ventricles, valves of the heart and all the soft tissues, and returns and sends this refleceted miror sound image in the machine, and also measures the reflections from the sound and reflects it on the screen as a silhouette.
