The price of infant cardiac ultrasound in a tertiary care hospital is 280 dollars, which is relatively high, why? Because it includes cardiac color Doppler ultrasound, tissue Doppler imaging, left heart function measurement, two-dimensional echocardiography, cardiac M-mode ultrasound and ventricular wall motion analysis, which is relatively comprehensive, so the price is relatively high. The price may be lower at the grassroots level, because the level of hospitals are different, including the content, the project is different, the cost is also different, its price from 120-300 dollars between the price varies, said the above is the current price of the three hospitals.
