WebThe QRS amplitude and R/S ratio are important in the diagnosis of ventricular hypertrophy. These values also vary with age (Tables 3-4 and 3-5 ). Because of the normal dominance of RV forces in infants and small children, R waves are taller than S waves in the right precordial leads (i.e., V4R, V1, V2) and S waves are deeper than R waves in the ... Web1 de dez. de 2001 · The study objective was to examine the prognostic predictive information of T-wave abnormalities in the setting of unstable coronary artery disease. The T-wave abnormality criterion was based on a new set of normal T-wave amplitude limits differentiated by gender, age, electrocardiographic lead, and QRS axis.
