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.
QT Prolongation. Recognition of a prolonged QT interval is complicated by the problems inherent in identification of T wave end and the inaccuracy of Bazlet's formula for correcting for heart rate. It may be preferable to judge the QT interval by changes in length or when it exceeds 50% of the R-R interval.T prolongation can be due to rare hereditary abnormalities, to type Ia anti-arrhythmics such as quinidine, and to hypocalcemia or hypomagnesia. The importance of recognizing prolonged QT interval is that it is associated with PVC's, ventricular tachycardia and fibrillation (ie., vulnerability to lethal arrhythmia).
