“…The upright T-waves in V1-V2 in conjunction with the right bundle branch block (RBBB) as a "mirror-image" of inverted T-waves in posterior leads V7-V9. It also can as be represented isolated lateral myocardial infarction (LMI), with the circumflex artery which is usually responsible for artery of infarction [7] . Life-threatening MI might be missed when RBBB is present, and the present of RBBB should be able to predict a proximal right coronary artery lesion [1] .…”

“…The upright T waves at V1–V2 in conjunction with the RBBB appear as a “mirror-image” of inverted T waves at posterior V7–V9. It could as represent isolated lateral myocardial infarction (LMI) of the circumflex artery, which is usually the artery responsible for infarction [ 9 ]. Life-threatening MI might be missed when RBBB is present, and the presence of RBBB should be able to predict a proximal RCA lesion [ 1 ].…”

“…One day after catheterization, the patient received coronary artery bypass grafting (CABG). Manzur-Sandoval et al [ 9 ] reported a patient with non-reperfused MI with RBBB. The coronary angiography showed TIMI Flow 0 at the proximal segment of the circumflex artery, and the patient received initial management with aspirin 300 mg, clopidogrel 300 mg, unfractionated heparin 4000 IU, and atorvastatin 80 mg.…”

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

Background 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. Case A 77-year-old Javanese male was admitted with middle back pain that he had had for several months but that had become worse in the past week. He received an oral nonsteroidal anti-inflammatory drug as analgesic therapy but the pain did not improve. The patient came to the emergency room and an electrocardiogram (ECG) showed complete RBBB and first-degree atrioventricular block. Three days after hospital admission, his chief complaint of pain had worsened, and ECG showed new deep arrow-head inverted wave at V3–V6, II, III, and aVF, as well as infero-anterolateral ischemia. The coronary angiography revealed 95% critical stenosis in left circumflex artery. Discussion 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.
