title: Detection of evolving right ventricular infarct during right coronary artery stent insertion using PRIME ECG body surface mapping with colour map reconstruction.
abstract: We present the evolutionary changes of isolated right ventricular infarction (RVI) in a patient undergoing right coronary artery stenting using a novel imaging system. Twelve ECG and body surface maps were recorded at 30-s intervals during right coronary angioplasty, during which a right ventricular branch of the right coronary artery (RCA) occluded, resulting in a short-lived episode of chest pain and minor changes on a 12 lead ECG. Using computer-derived colour reconstruction of the ECG data, the changes of isolated right ventricular infarction is obvious, in contrast to the transient and equivocal changes seen on the 12 lead ECG.
  
  
  CONCLUSIONS
  Isolated RVI may be missed on 12 lead ECG criteria. Body surface mapping (BSM) allows unequivocal diagnosis of isolated RVI by colour map reconstruction that is able to localise the ischaemic change.
