ABSTRACT

Objective To assess the value of ECG in the diagnosis of acute pulmonary embolism (APE). Methods Twenty-eight patients with APE were included,with mean age of 56?16,and PaO 2,electrocardiogram (ECG),echocardiogram (ECHO) and ventilation/perfusion lung scan were performed. Results 96.4% patients had risk factors,and had different degree of hypoxia. 92.9% patients had ECG changes,most of whom (57.1%) showed ST-T changes. The ventilation/perfusion lung scan confirmed the diagnosis. Conclusion Considering the clinical symptom,arterial blood gas analysis,the early changes of ECG are useful in the diagnosis of the APE.
