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.
To meet criteria for LGL, the 12-lead ECG taken during a period of normal sinus rhythm must demonstrate a PR interval less than or equal to 0.12 second and a normal QRS upstroke and duration, as in the image below. ECG demonstrating a short PR interval of approximately 100 ms and normal QRS. One of the most useful diagnostic tools is a 12-lead ECG recorded during a paroxysm of tachycardia.
