Actually, when Xia Shu was at Fuwai Hospital, he wasn't familiar with echocardiography either, in terms of both theory and practical operation. He rarely engaged with it, and usually relied on the assistance of ultrasound doctors to complete echocardiography examinations. After coming to the Sanbo Hospital Surgery Research Institute, Xia Shu began to learn how to perform echocardiography and make diagnoses himself. Now, Xia Shu had mastered the principles and operations of ultrasound, and he was very proficient in them.
Yang Ping watched as Xia Shu operated; the ultrasound transducer began to examine Mr. Karen's heart, comprehensively evaluating the size of the heart chambers, the thickness of the ventricular walls, the opening and closing of the valves, and the movement of the myocardium, not missing any detail, especially the condition of the valves, which needed to be carefully assessed to detect any subtle potential risks.
