ECG Analysis - developinganaesthesia

(isolated LPFB is exceedingly rare; it is a combined clinical and ECG diagnosis) III. QRS AMPLITUDE. High voltage – probable left ventricular hypertrophy (LVH); criteria: S in V1 plus R in V5-6 (whichever is the larger) ≥ 35 mm. sensitive but not specific; the larger the sum the more specific S-V1 + R-V5 ≥ 35 mm. R in aVL ≥ 13 mm ................
