Electrocardiographic changes similar to Wellens\u2019 wave are not exceptional to acute coronary occlusion and can also be seen in cardiac and non-cardiac conditions, such as left ventricular hypertrophy, persistent juvenile T wave, bundle branch blocks, cerebral haemorrhage, pulmonary oedema, pulmonary embolism, pheochromocytoma, Takotsubo syndrome, digitalis and cocaine-induced coronary vasospasm. Cocaine-induced pseudo-Wellens\u2019 syndrome should be considered as one of the differentials, since cocaine is used frequently by young adults and can cause left anterior descending coronary vasospasm mimicking Wellens\u2019 syndrome. Initiation of the beta-blocking agent in pseudo-Wellens\u2019 syndrome as a part of acute coronary syndrome management can be disastrous. We illustrated a case of cocaine-induced pseudo-Wellens\u2019 syndrome presented with typical chest pain associated with Wellenoid ECG.<\/jats:p>","DOI":"10.1136\/bcr-2017-222835","type":"journal-article","created":{"date-parts":[[2017,12,14]],"date-time":"2017-12-14T23:40:46Z","timestamp":1513294846000},"page":"bcr-2017-222835","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":20,"title":["Cocaine-induced
