VCG ST correlates with epicardial changes in canines; extends preclinical validation but leaves open human translation.
Does an external 3-lead orthogonal vectorcardiographic system accurately reflect epicardial ST-segment changes during myocardial ischemic injury in a canine model?
Precordial VCG ST magnitude accurately reflects epicardial ST changes during myocardial ischemia in a canine model, suggesting potential clinical utility as a rapid, noninvasive assessment tool.
