Abstract: To analyze the changes of echocardiogram and pulmonary function indexes in children with wheezing diseases and their clinical significance. Children with wheezing diseases were taken as the observation group and healthy children at the same time as the control group. After admission, the two groups were examined by echocardiography and lung function. The basic data, echocardiogram and lung function tests were compared between the two groups. There was no significant difference in the data of the basic data items such as gender, age, height and body weight between the two groups (P>0.05). The pulmonary systolic pressure and the maximum reflux velocity index of the tricuspid valve in the observation group were higher than those in the control group (P<0.05). The kilogram tidal volume, peak time ratio and peak volume ratio were lower than that in the control group (P<0.05). Echocardiography and pulmonary function indexes can provide a reference for the clinical diagnosis of children with wheezing disease, and help to formulate subsequent treatment plans, which has clinical value.
