Quantitative criteria for the diagnosis of dorsal infarction using the Frank vectorcardiogram

Influence of Posterobasal Myocardial Infarction (PBMI) on the QRS and T Wave Amplitude in the Limb and V₆ Leads

“…However, such an assumption does not appear to be warranted. Our ECG findings are in accordance with the vectorcardiographic findings of recent reports from W alsh [15], Hoffman [6] and W o lff [16] and modify the previously mentioned thoughts for the following reasons. The height of the QRS complex in limb and V6 leads depends on the projection of the maximum vector on each lead.…”

“…Following Levy's [9] and Elek's [3] observations that several infarctions are associated with a prominent R wave in lead V,, Grant [4,5] described the strictly posterior infarction. Thereafter, various authors called this entity strictly [10], di rect [11], dorsal [6,13], true [8], high posterior [14] and finally posterobasal [16] myocardial infarction (PBMI). This last term is now preferred as more indicative of both the anatomical and spatial location of the lesion.…”

Vectorcardiogram versus Thallium-201 Planar Scintigram and Single-Photon Emission Computed Tomogram in the Diagnosis of Inferior Myocardial Infarction

“…The vectorcardiographic (QRS) criteria used for the diagnosis of inferior or posterior myocardial infarction were those of Hoffman et al [1,2]. The diagnosis criteria for inferior lateral myocardial infarction were those of Chou et al [3] and for anteroseptal myocar dial infarction those of Hugenholtz et al [4].…”
