Wellens syndrome is described asbiphasic or deeplyinverted T waves in the precordialleads thatis indicative of criticalstenosis of the leftanteriordescendingartery. It isseenin a subset of patients withunstableanginaduring the pain-free interval. . Similar characteristic ECG changes associated with causes other than LAD stenosis have been described as pseudo-Wellens syndrome. In this case report, we present a young 31-year-old man who presented with characteristic Wellens ECG changes in the setting of pulmonary embolism with right ventricular strain., biphasic T waves in the setting of pulmonary embolism are rare. Pulmonary embolism was seen in our patient three weeks after starting risperidone. There is a reported association between antipsychotic drugs and increased risk of thromboembolism. Risperidone could have potentially contributed to the pulmonary embolism in our patient given the temporal association and absence of risk factors.
