ST Analysis - Chapter 10 

F.  Jager

Left ventricular hypertrophy by voltage (R wave 12-13 mm in aVL) plus left atrial abnormality (LAA). The QRS axis is somewhat leftward (-7 degrees), but without frank left axis deviation (more negative than -30 degrees) or evidence for left anterior fascicular block (-45 degrees or more negative). Although LVH alone may be associated with ST-T abnormalities (sometimes referred to as a "strain pattern"), like those in lead aVL, the prominent horizontal or downsloping ST depressions in other leads (I, II, aVF, V5, V6).
