Carotid ultrasound and heart ultrasound (cardiac ultrasound) can be done together, there is no influence or intervention between the two, and there will be no impact on the results of the examination and physical condition. Carotid ultrasound is mainly to observe the structure of the blood vessels in the neck, to observe whether there is obvious atherosclerosis, whether accompanied by obvious narrowing of the lumen; cardiac ultrasound is mainly to observe the structure of the heart, whether there is developmental deformity, whether accompanied by obvious abnormalities of the valves’ functioning status; there is no interference between the two examinations, and there is no impact on the physical condition, so it is possible to do them together. Before doing the examination, try to ensure that the physical condition is stable, avoid too much emotional tension, and if you find any abnormalities of blood vessels or heart condition, you need to consult a doctor in time for observation and standardized treatment under the guidance of a clinician.
