1. Determine the doctor you want to see, and if possible, make an appointment with the doctor you want to see for a possible visit and surgery. Before you see me, you should pay attention to the clinic hours and closing information on the website to avoid a wasted trip. 2.Apply for a medical card (ID card required) at the hospital outpatient clinic by yourself or by a friend, register at the cardiovascular center nurse station on the third floor of the clinic with your medical card, and attend the clinic in order. 3.When the test results come out, go to the doctor’s clinic to see the doctor you want to see, or go directly to the ward to see the results. If it is inconvenient for out-of-town patients to visit the clinic, they can contact me by telephone consultation to help you interpret the test report. 4. For patients who need to be hospitalized, the doctor will issue an admission card, leave contact information, ask about the approximate time of admission, and wait for notification of admission. If you have special requirements, such as a single room, explain in advance. During this period, if the child encounters special circumstances such as cold and pneumonia, he or she can communicate with me by phone to see if the hospitalization time needs to be changed. 5.After admission, we will ask the bedside doctor and the surgeon about the operation time, and determine who and when to talk to before the operation.
