    • Abstract:
      The article focuses on the Valsalva maneuver, an emergency method published in the "New England Journal of Medicine" for the cure of angina pectoris associated with heart disease. It states that the method works by holding one's nose and blowing while the mouth is closed which produces a similar effect when one takes nitrite or nitroglycerin. However, it tells that its mechanism is not yet clear and that it can be harmful for individuals with histories of stroke or high blood pressure.
