e/Vagus reflex

Information
has gloss	eng: The vagus nerve plays a role in (amongst other things) controlling the pulse. The vagus reflex is a reaction which can reduce the pulse rate. Intentionally inducing a vagus reflex is sometimes used to treat tachycardia (racing pulse). The following stimuli may produce the vagus reflex: * tensing the lower abdomen (similar to straining at stool) * gentle pressure on the closed eyes * a gulp of ice-cold water * splashing ice-cold water on the face * immersing the arms in ice-cold water * finger stuck down the throat * the insertion of an IV needle * cough or sneeze (involuntary or autonomic works best) * holding breath (after exhaling) - see Valsalva manoeuvre * insertion of an object into the uterus such as an IUD
