Q. Define ST Elevation in aVR?

Lead aVR often develops ST elevation as a reciprocal of ST depression in lead V2 to V6 or leads 2 and 3. It may occasionally show ST elevation in the absence of significant changes in the other leads. aVR is positioned so that it reflects the left ventricular cavity and when the right and left coronary beds are ischaemic and cancel out, changes in the apex can be manifested. It has been suggested that ST elevation in aVR of a 0.5 mm is significant for ischaemia. It has been reported that this finding has a sensitivity of 89 per cent but a specificity of only 44 per cent for LAD disease.
