Exercise-Induced ST-Segment Elevation in ECG Lead aVR Is a Useful Indicator of Significant Left Main or Ostial LAD Coronary Artery Stenosis

Abstract: Stress (ETT)-induced STE in lead aVR is an important indicator of significant LMCA or ostial LAD stenosis and should not be ignored.

“…Several studies have highlighted its usefulness for the detection of demand ischemia during exercise and for the recognition of left main and proximal left anterior descending stenoses. 36,37 It is likely that much of this diagnostic value is attributable to the relationship of the derived lead to the axis of the left ventricle as a result of torso placement of the electrodes (which actually makes a torso-based -aVR somewhat similar to CM 5 in axis). It should be noted that the spatial diagnostic information contained in aVR cannot exceed that of the other routine electrocardiographic leads because it is mathematically dependent on (and calculated from) any 2 bipolar limb leads.…”

“…Exercise-induced ST-segment elevation ≥1 mm occurring in a non-infarct territory usually indicates transmural ischemia and is associated with severe proximal coronary [14]. While ST-segment depression does not localize the site of coronary ischemia, the localization of ST-segment elevation is relatively specific for the distribution of the coronary artery involved.…”

“…Kliničkom studijom koja je pratila bolesnike podvrgnute testu opterećenjem protokola po Bruceu dokazano je da je elevacija ST segmenta u aVR odvodu ≥ 1mm na pomenutom testu bila prediktor stenoze glavnog stabla leve koronarne arterije ili ostijalne stenoze RIA, što je dokazano naknadnim invazivnim hemodinamskim ispitivanjem sa senzitivnošću 75% i specifičnošću 81% (26).…”
