I don't know when you got the adult undergraduate education. According to the relevant provisions of the Law on Medical Practitioners, there are some restrictions on adult undergraduate courses. You can refer to it All the ECG room doctors in our hospital have obtained the qualification of clinical practitioners, and some have obtained the qualification certificate of large-scale equipment. As for the license of Chinese medicine, some units can't engage in western medicine, so they should adjust measures to local conditions. But the most basic thing is that the unit agrees to let you work in the ECG and B-ultrasound room, and you have to pass the examination as a western medicine practitioner. As for large equipment, I don't know. I hope it helps you.
