From: Myocardial bridging presenting as myocardial ischaemia induced cardiac arrest: a case report
The electrocardiogram (ECG) performed in the local emergency department showed a normal sinus rhythm with a right bundle branch block (RBBB) with ST elevation and Q-waves over V1–V4 (a). ECG performed at our institution showed complete resolution of ST elevation on V1–V4 (b). Coronary angiography showed significant myocardial bridging in the distal segment of the left anterior descending coronary artery and diagonal branch with compression up to 100% stenosis during systole (arrow) (c, d)
