Abstract：Objective To explore the diagnostic value of ECG changes in children with mycoplasma pneumonia complicated by myocardial damage. Methods A total of 296 children with mycoplasma pneumonia were selected. According to the absence or presence of ECG abnomalities, they were divided into normal ECG group (82 cases) and abnormal ECG group (214 cases). One hundred health children were selected as control group. Basic conditions and difference of myocardial damage were comparatively analyzed among the three groups. The correlation between ECG abnormalities and myocardial damage, and the proportion of each type of ECG abnormalities were also analyzed. Results There is no significant difference in age or sex ratio among groups (P>0.05). The myocardial enzyme indexes in the abnormal ECG group are significantly higher than those of the normal ECG group
and the control group. Only each myocardial enzyme index of the control group is within the normal reference range. And the difference of each index is statistically significant among the three groups (P<0.01). Among the children with mycoplasma pneumonia, ECG abnormalities are significantly correlated with myocardial damage (χ2=8.248，P<0.05), that is, the probability of complicated myocardial damage significantly increases in child patients with ECG abnormalities. In the child patients with mycoplasma pneumonia, various types of ECG abnormalities are found, including arrhythmias and ST-T changes, among which sinus tachycardia, ST-T changes and sinus arrhythmia are more common, accounting for 44.86%, 34.11% and 12.15%, respectively. Conclusion ECG abnormalities have important diagnostic value in child patients with mycoplasma pneumonia complicated by myocardial damage, which help to make early diagnosis and treatment, and improve the prognosis.
