Objective:To evaluate the predictive value of electrocardiographic SⅠQⅢTⅢ pattern in patients with acute pulmonary embolism . Method: ECG was analyzed retrospectively in 102 patients with acute pulmonary embolism confirmed by spiral CT scan and Compared the clinical data between SⅠQⅢTⅢ positive and negative group. Result: In 102 patients 29 cases have positive SⅠQⅢTⅢ , positive rate was 28.4%. In SⅠQⅢTⅢ positive group and SⅠQⅢTⅢ negative group, 41.4% vs 69.9% have vulnerable diagnosis before admitted, respectively(P < 0.05),as well as the massive PE 48.3% vs 23.3% (P < 0.05),mortality rate 24.1% vs 10.9(P < 0.05),bilateral PE 86.3% vs 65.8%(P < 0.05) and right side PE 10.3% vs 31.5%(P < 0.05).Conclusion : positive Electrocardiographic SⅠQⅢTⅢ could not be served as the basic diagnosis criteria for acute PE . positive SⅠQⅢTⅢ ECG could decrease the misdiagnosis of acute PE, indicate higher possibility of bilateral and massive acute PE.
