The normal resting adult human heart rate ranges from 60â100 bpm. Tachycardia is a fast heart rate, defined as above 100 bpm at rest. Bradycardia is a slow heart rate, defined as below 60 bpm at rest.During sleep a slow heartbeat with rates around 40â50 BPM is common and is considered normal.he normal resting adult human heart rate ranges from 60â100 bpm. Tachycardia is a fast heart rate, defined as above 100 bpm at rest. Bradycardia is a slow heart rate, defined as below 60 bpm at rest.
â¢ The incidence of anisocoria in the newborn period is not well described. Additionally, the normal range of infant pupil size is not well defined. Eighty-eight healthy newborns were evaluated. Pupil size and color were obtained from photographs. The mean (Â±SD) pupil size was 3.8 Â± 0.8 mm. There was no statistical difference between right and left eyes.
Kohnen@em.uni-frankfurt.de. PURPOSE: To determine scotopic pupil diameter in a normal pediatric population. METHODS: Scotopic pupil size was measured in 166 eyes of 83 children with a mean age of 6.01+/-4.11 years (range 0.51-14.26 years) using the light and hand-held Colvard infrared pupillometer.Measurements were performed under dim illumination after 2 min of dark adaptation.cotopic pupil size in a normal pediatric population using infrared pupillometry.
