摘要
目的 通过分析急性肺栓塞 (APE)患者资料 ,重点评价心电图 (ECG)在APE诊断中的作用。方法 APE患者 2 8例 ,平均年龄 (5 6± 16 )岁 ,结合临床表现、ECG和超声心动图 (ECHO)等检查 ,同时行同位素肺通气灌注扫描确诊。结果 96 4 %患者存在危险因素 ,临床表现为不同程度的低氧血症 ;92 9%有ECG变化 ,其中以ST T改变最为多见 ,占 5 7 1%。结论 ECG改变敏感性较高 ,早期发现ECG的异常变化 ,结合临床症状、血气分析对肺栓塞的及时诊断有重要作用。
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.
