How long does an interventional cardiographic exam take?

Cardiac interventional angiography usually takes 20-30 minutes.

If the patient is more cooperative, the degree of cardiac stenosis is low, the doctor is more skilled and efficient, and the examination time is relatively short, usually about 20 minutes. If the patient is less cooperative, the degree of cardiac stenosis is high, and the examination difficulty is easy to increase, the doctor is unfamiliar and the efficiency is low, the examination time will also be prolonged, generally about 30 minutes.

After the examination, the patient should closely monitor vital signs, such as heart rate, respiration, blood pressure, oxygen saturation, etc., and inform the doctor in time if there is any abnormality.
