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.
First Degree AV Block. First degree AV block is simply an increase in the time it takes for the impulse from the atrium to reach the ventricles. In a normal heart rhythm, the PR interval is in the range of .12 to .20 seconds. In first degree AV block, that interval will exceed .20 seconds and can be as long as .50 seconds in extreme examples. The cause for this delay lies in the AV node.
