ECG characteristics and clinical datum analysis of 56 aged patients with pulmonary embolism / 心血管康复医学杂志

ABSTRACT

Objective:To explore clinical characteristics and diagnosis in aged patients with pulmonary embolism. Methods:The data of electrocardiogram (ECG),clinical characteristics and diagnosis were summarized and ana-lyzed in 56 aged patients with pulmonary embolism.Results:The most frequent symptom was exertional dyspnea (69.6%).ECG had characteristic changes in 12 patients (21.4%).All 56 patients received multi-slice spiral CT pulmonary arteriography,and thrombus within pulmonary artery was found in all patients (100%);38 cases re-ceived nuclide lung ventilation perfusion scanning,the results were 32 cases (84.2%)with mismatching pulmonary perfusion and ventilation imaging;Ultrasound examine found there were phlebothrombosis in deep vein of lower limb of 26 cases (46.4%).MisdiagnosisThe 26 cases (46.4%)were misdiagnosed.A total of 14 cases (53.8%) were misdiagnosed as respiratory system diseases,including eight cases of infectious shock and six cases with pulmo-nary infection;12 cases (46.2%)were misdiagnosed as circulatory system diseases,including five cases of acute cor-onary syndrome,four cases of heart failure and three cases of cardiogenic shock.Conclusion:The most frequent symptom is exertional dyspnea in aged patients with pulmonary embolism;ECG has characteristic changes only in few patients;the pulmonary arteriography is major diagnosis method.
