To deodorize the bathroom quickly, wipe down the walls and other surfaces with white vinegar. Focus on the area around the toilet, where the walls may have absorbed smells and more. If toilets are flushed with the lid up, contaminated water vapor can spray several feet, and linger on surfaces. 7. For an even simpler odor solution, pour vinegar into the toilet and let it work for an hour or so before flushing.
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.
I. Problem/Condition. The normal PR interval is from 0.12-0.2 seconds and is measured on the EKG from the beginning of the P wave to the beginning of the QRS complex. Aleterations in the PR interval may be physiologic or may represent abnormal progression of electrical conduction from the atria to the ventricles through the AV node.
