Objective To investigate the clinical diagnostic value of electrocardiogram in acute pulmonary embolism (APE). Methods A total of 72 patients with suspected APE in hospital from March 2016 to December 2017 were selected, all of the patients underwent electrocardiogram examination. The pulmonary angiography results were taken as the gold standards, the clinical diagnostic value of electrocardiogram in APE and electrocardiogram changes were analyzed. Results Sixty-five cases of APE were diagnosed by pulmonary angiography among the 72 cases; the accuracy, sensitivity, specificity, positive predictive value, negative predictive value of electrocardiogram were 90.28%, 96.92%, 28.57%, 92.65%, 50.00%; the electrocardiogram of 5.56% of patients was within the normal range, there were 72.22% of sinus tachycardia, 2.78% of ventricular premature beat, 12.50% of right axis deviation, 11.11% of avR upward main wave and right bundle branch block, 5.56% of P-pulmonale, 13.89% of SⅠQⅡTⅢ, 25.00% of V1-3T wave inversion, 8.33% of V1-6T wave inversion. Conclusions The electrocardiogram has better clinical diagnostic value in APE, which can increase the diagnostic accuracy.
