Abstract：It is particularly important to give patients with acute pulmonary embolism(APE) complicating acute coronary syndrome(ACS) correct and timely diagnosis and treatment for its severity. When persistent chest pain, serious right ventricular dysfunction, and refractory atrial arrhythmia occur in APE patient, APE complicating ACS should be considered. The most convenient and practical diagnostic tool is electrocardiogram(ECG), and the diagnostic criteria are summarized as follows: (i) the conventional ECG changes of APE +ST segment changes in left chest leads; (ii) T wave inversions are mostly found in Ⅲ, V1, and V2 lead of APE patients, with the deepest in V2 lead while they synchronously appear in left chest leads, deeper and wider than those in right chest leads; (iii) ST segment elevation is observed in right chest leads and aVR lead.
