First-degree atrioventricular block. First-degree atrioventricular block (AV block), or PR prolongation, is a disease of the electrical conduction system of the heart in which the PR interval is lengthened beyond 0.20 seconds. In first-degree AV block, the impulse conducting from atria to ventricles through the atrioventricular node (AV node) is delayed and travels slower than normal.
ATSDR has derived an intermediate-duration inhalation MRL of 0.002 ppm for chlorine based on a. minimal LOAEL of 0.5 ppm for tracheal lesions in rats exposed 6 hours/day, 5 days/week for 62 days. (Kutzman 1983). An uncertainty factor of 90 was used (3 for extrapolation from animals to humans with. dosimetric adjustment, 3 for use of a minimal LOAEL, and 10 for human variability). ATSDR has derived a chronic-duration inhalation MRL of 0.00005 ppm for chlorine based on an.
