Right bundle branch block evolving to myocardial ischemia in a patient with chronic middle back pain: A case report

A right bundle branch block (RBBB) is rarely found in patients with myocardial infarction (MI). In addition, back pain is an atypical complaint in patients with angina. It is a challenge for clinicians to recognize and carefully assess a patient’s complaints even if they are admitted for pain that is “atypical” of MI. When ECG shows changes, clinicians need to pay attention to a tricky, hidden, and life-threatening occlusion of the coronary artery.
