Can vectorcardiogram criteria unmask inferior Q-waves in Mason-Likar 12-lead ECG?

Background: Torso placement of 12-lead ECG electrodes is commonly used to reduce noise. The main differences between Mason-Likar (torso) and standard placement on wrists and ankles are frontal plane QRS-axis and missing Q-waves with inferior myocardial infarction (IMI). We developed and tested a combination of Frank orthogonal lead estimation, Mason-Likar (ML) correction and VCG criteria to maintain adequate inferior MI (IMI) detection with torso electrode placement.
