Electrocardiograms of the patient: A) electrocardiography on admission to the emergency department, showing ventricular tachycardia with the right bundle branch block configuration and a superior axis; and B) post-cardioversion electrocardiography, showing a normal sinus rhythm

The use of direct current cardioversion restored the sinus rhythm (Figures 1A and 1B) and improved the patient's blood pressure and hemodynamic state.
Coronary angiographic studies of the patient: A) left anterior oblique caudal view, revealing a patent left descending anterior coronary artery (LAD) and circumflex artery (CX) without thrombus, dissection, or coronary slow flow; B) left anterior oblique cranial view, revealing a patent LAD and CX without thrombus, dissection, or coronary slow flow; C) right anterior oblique view, revealing a patent right coronary artery (RCA) without thrombus, dissection, or coronary slow flow; and D) left ventriculogram obtained from the right anterior oblique view, showing the true left ventricular aneurysm (arrow) on the posterobasal segment of the left ventricle

However, cardiac ventriculogram confirmed that the position of the aneurysm was on a posterobasal segment (Figures 2).
