The Romhilt-Estes Criteria performs well in regard to sensitivity (50-54%) and specificity (95-97%) in the detection of Left Ventricular Hypertrophy (LVH) on EKG. Other research (Pewsner, et al) find that in hypertensive patients, EKG criteria is quite inadequate to rule out LVH (is helpful in identifying it; but often patients with LVH do not meet criteria on EKG)
Other simple rules:
