  • Title: [On the diagnostic value of indirect electrocadiographic signs of left posterolateral basal infarction].
    Author: de Micheli A, Aranda A, Medrano GA.
    Journal: Arch Cardiol Mex; 2007; 77(2):150-5. PubMed ID: 17715628.
    Abstract:
    The left basal posterolateral infarct does not give pathological Q waves nor ventricular QS complexes in the low lateral leads V5 and V6. For that, the increased voltage of R waves in the lead V2 and or transitional leads V3 and V4, constitutes only an indirect sign of the presence of dead myocardium in the left posterolateral basal regions. Naturally, in these cases, a differential diagnosis with left ventricular or biventricular hypertrophy is mandatory. Therefore it is suitable to register left posterior thoracic leads V7-V9 or, preferably, a complete thoracic circle. We present here three examples: two experimental and another clinical, in which the electrocardiographic findings corresponded to anatomical data of a left posterolateral basal infarction. This fact speaks for a no absolute but relative diagnostic value of the indirect electrocardiographic signs of altered ventricular depolarization and repolarization in the left posterolateral basal regions of the left ventricle.
