Body Mass Index (BMI) Calculator

BMI is body weight divided by a power of height, usually (height)2, which is said to be independent of stature. Calculations based on values for ideal body weight suggest that BMIs for normal men and women should be in the range of 18.5 to 25 kg/m2. Indeed, this range roughly corresponds to the 10th to 75th percentile values recorded from adult individuals. For infants and children, average BMI values change with age, from 13 kg/m2 at birth, to a peak of 18 at about 1 year, a nadir of 15 at about age 6 years, and then a rise to adult values during adolescence.

Common Diagnostic Criteria for Left and Right Atrial Abnormalities

Left Atrial Abnormality

  • Prolonged P wave duration of >120 msec in lead II
  • Prominent notching of the P wave, usually most obvious in lead II, with an interval between the notches of >40 msec (p mitrale)
  • Ratio between the duration of the P wave in lead II and the duration of the PR segment of >1.6
  • Increased duration and depth of the terminal negative portion of the P wave in lead V1 (the P terminal force) so that the area subtended by it exceeds 0.04 mm-sec (Morris index)
  • Leftward shift of the mean P wave axis to between -30 and +45 degrees Continue reading “Common Diagnostic Criteria for Left and Right Atrial Abnormalities”
