What is the difference between cardiac ultrasound and electrocardiogram and coronary CT?

Echocardiography, electrocardiogram, coronary angiography and coronary CT are commonly used in the examination and diagnosis of heart diseases. If the heart is regarded as a house, the echocardiography mainly looks at the structure of the house, the electrocardiogram mainly looks at whether there is something wrong with the wire, and the coronary CT mainly looks at the patency of the water pipe. The heart ultrasound senses whether the hardware structure of the house is defective due to old age or other reasons, the electrocardiogram can see whether the house current is regular and unimpeded, and whether the current in a certain room leads to the burning of the light bulb. and then affect the normal operation of the whole circuit.

If the heart is regarded as a house, the echocardiography mainly looks at the structure of the house, the electrocardiogram mainly looks at whether there is something wrong with the wire, and the coronary CT mainly looks at the patency of the water pipe.

Generally speaking, echocardiography is used to detect whether the hardware structure of the house is defective due to old age or other reasons, such as the size of the room, walls, doors and windows. The electrocardiogram can see whether the house current is regular and unimpeded, and whether there is an excessive current in a room, which leads to the burning of the light bulb, which in turn affects the normal operation of the whole circuit. Coronary artery CT and coronary angiography are to check the patency and occlusion degree of cardiac great arteries (coronary arteries), which can effectively judge the existence of coronary artery stenosis and other problems. All kinds of cardiac examination methods have their own functions and advantages and can not replace each other. (source: Beijing Chaoyang Hospital affiliated to Capital Medical University)
