Electrical storm after conus branch occlusion

Abstract Ventricular arrhythmias can occur in the course of myocardial infarction due to ischemia of substantial parts of the myocardium and often reside after the occluded vessel has been reopened. We hereby report a case of a 73-year-old male, who presented with acute coronary syndrome and was treated for a subtotal stenosis of the ostial right coronary artery. Subsequently, he developed Brugada syndrome type ECG changes and electrical storm, which was later explained by occlusion of the conus branch. After re-opening of the occluded vessel no further arrhythmias were recorded.
