目的:探讨急性肺栓塞早期心电图(ECG)的临床特征。方法:回顾性分析了2009.09-2012.09入住我院的122例急性肺栓塞患者的临床资料,对本组患者早期心电图特点进行分析与研究。结果:本组患者中有92.62%(113/122)的患者存在基础性的危险因素,临床表现症状主要为呼吸困难、胸闷、咳嗽以及胸痛等方面的症状,其体征主要以呼吸急促以及心跳过速和下肢肿胀等方面的体征有着一定的关系。113例存在基础性危险因素的患者血气分析为程度不同的低氧血症、肺泡-动脉血氧分压以及低碳酸血症。结论:ECG改变敏感性非常高,并发现ECG出现早期异常性的变化,结合易患因素以及临床主要特征、患者的血气分析对肺栓塞的早期诊断具有十分重要的作用。血浆D-二聚体正常对APE的早期临床诊断具有较大的排除作用。
Objective: To investigate the clinical features of early electrocardiogram (ECG) in acute pulmonary embolism. Methods: The clinical data of 122 acute pulmonary embolism patients admitted to our hospital from January 2009 to September 2012 were retrospectively analyzed. The characteristics of early ECG in this group were analyzed and studied. Results: There were 92.62% (113/122) patients in our group with the basic risk factors. The clinical manifestations were mainly dyspnea, chest tightness, cough, chest pain and other symptoms. The main symptoms were shortness of breath and heartbeat Speed and lower limb swelling and other aspects of the signs have a certain relationship. Blood gas analysis of 113 patients with underlying risk factors for varying degrees of hypoxemia, alveolar-arterial partial pressure of oxygen and hypocapnia. CONCLUSIONS: The sensitivity of ECG changes is very high, and the early abnormal ECG changes are found. Combined with the predisposing factors and the main clinical features, the blood gas analysis of patients plays an important role in the early diagnosis of pulmonary embolism. Plasma D-dimer normal APE early clinical diagnosis has a greater exclusion.
