This power-pitching showdown should keep the scoring to a minimum.
WebUsing 90-190 cm/sec as the normal range, the peak velocity shifted from normal to abnormal levels by changing respiratory state in 17 (45%) of 38 studies. Using 60 cm/sec as the lower normal limit, the peak velocity fell below the normal range with inspiration in 10 (26%) of 38 studies. WebMedial velocity is normally <8 cm/s and lateral velocity is normally <10 cm/s. Young healthy people may display higher velocities. If medial and lateral velocities are measured, the mean value is used. The sweep speed should be set to 50 mm/s to 100 mm/s. E/e’ ratio and LVEDP
