Abstract

It is rare to observe ST-segment elevation in only the anterior leads and not the inferior leads during right coronary artery occlusion. We describe a case with acute myocardial infarction (MI) by right coronary artery occlusion who developed ST-segment elevation only in the precordial leads V1 to V3.

Figure

  • Fig. 1 Standard 12-lead electrocardiography recorded from a patient with chest pain. Note the presence of ST-segment elevations in leads from V1 to V3, and no ST-segment deviation in leads II, III, and aVF.

  • Fig. 2 Coronary angiographic findings of the patient. A: angiographically normal left coronary system. B: the inferior wall of the left ventricle was supplied with rich collaterals from left coronary system. C: coronary angiography showing complete luminal occlusion of the RCA proximally. D: the RCA after percutaneous coronary intervention. RCA: right coronary artery.
