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 ... Web17 de fev. de 2016 · However, the earliest findings on an ECG are subtle changes in the T-wave shape and size. When a coronary artery is occluded, within the first 30 minutes, the T-wave amplitude increases [2]. The next changes are ST-segment elevation and loss of the R-wave amplitude. If the vessel remains occluded, Q-waves develop.
