Abstract:
Objective To explore the value of ECG score in predicting the danger level of acute pulmonary embolism (APE). Methods Clinical data of 108 patients with APE who were admitted to and treated in our hospital from January 2012 to January 2014 were retrospectively analyzed. According to patients' disease conditions, 41 patients were as-signed to low-risk group, 61 patients in medium-risk group, and 6 patients in high risk group. ECG was carried out for patients 24 hours after the admission. Relations between waves of ECG and risk stratification were studied. Relations of number of leads by ECG T wave with anteroposterior diameter of right ventricle, SPAP, PaCO2, pH value and PaO2 were analyzed. Results Commonly seen changes of ECG for patients with APE were as follows: Precordial T wave inversion was seen in 193 patients, among whom patients were V1, and 58 patients were V2, followed by 49 cases of V3 patients. Number of leads by T wave inversion was not correlated with arterial blood pH value, anteroposterior diameter of right ventricle, and PaCO2. Number of leads by T wave inversion was positively correlated with SPAP, and was negatively correlated with PaO2 in arterial blood gas analysis. Conclusion ECG and the danger level of patients with APE have good correlations, and ECG has favorable predicting values for patients with APE.
