DIFFERENCES IN NEGATIVE T WAVES IN RIGHT PRECORDIAL LEADS BETWEEN ACUTE PULMONARY EMBOLISM AND WELLENS SYNDROME

The aim of this study is to estimate the possibility of using the differences of negative T waves in the right precordial leads for the differential diagnosis of the pulmonary thromboembolism (pulmonary embolism) and Wellens syndrome. We studied the first ECGs with T -wave inversion in leads V 1 –V 3 in 70 patients (38 patients with pulmonary embolism and 32 patients with Wellens syndrome). The ratio of the magnitude of negative T wave in the lead V 1 to the magnitude of negative T wave in the lead V 3 (T V1 /T V3 ) was more than 0.5 in all patients with pulmonary embolism and in only one (4.5%) patient with Wellens syndrome. So, this criterion T V1 /T V3 >0.5 may by useful for the differential diagnosis of these diseases.
