Hi, I am working as a cardiovascular technologists in USA. I am health professionals and deal with the circulatory system of human body. Before my current job, I also lead a team of exotic car rental Portland, Oregon. I do ultrasound to examine the heart chambers, valves, and vessels which referred to as cardiac sonographers. I also assist physicians who perform transesophageal echocardiography which involves placing a tube in the patient’s esophagus to obtain ultrasound images.
