WebUsing leads I and aVF the axis can be calculated to within one of the four quadrants at a glance. If the axis is in the "left" quadrant take your second glance at lead II. both I and aVF +ve = normal axis; both I and aVF -ve = … WebPathological Q-waves are ≥0,03 s and/or amplitude ≥25% of R-wave amplitude in same lead, in at least 2 anatomically contiguous leads. Is the R-wave progression in the chest leads (V1–V6) normal? Is the electrical axis normal? Electrical axis is assessed in limb leads and should be between –30° to 90°. Common findings
