2D ECG differences in frontal vs preferential planes inpatients referred for percutaneous transluminal coronary angioplasty ?
We compared cardiac vectors of ischemic and healthy patients in two different planes. Planes under study: the Einthoven's plane (FP) and a PCA-transformed plane (PP). We compared the ability to discriminate ischemia from health of both representations. The FP enabled the discrimination of ischemic patients while the PP did not.
