answers: the atrioventricular node
context: (also known as grade 4 vaginismus), the most severe form of vaginismus, the patient elevates the buttocks, retreats and tightly closes the thighs to avoid examination. Pacik expanded the Lamont classification to include a fifth degree in which the patient experiences a visceral reaction such as sweating, hyperventilation, palpitations, trembling, shaking, nausea, vomiting, losing consciousness, wanting to jump off the table, or attacking the doctor. The Lamont classification continues to be used to the present and allows for a common language among researchers and therapists. Although the pubococcygeus muscle is commonly thought to be the primary muscle involved in vaginismus, </s> to complete heart block. 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. It has a prevalence in the normal (young adult) population of 0.65-1.1% and the incidence is 0.13 per 1000 persons. The most common causes of first-degree heart block are an AV nodal disease, enhanced vagal tone (for example in athletes), </s> about 62.5%. Cimino fistula A Cimino fistula, also Cimino-Brescia fistula, surgically created arteriovenous fistula and (less precisely) arteriovenous fistula (often abbreviated AV fistula or AVF), is a type of vascular access for hemodialysis. It is typically a surgically created connection between an artery and a vein in the arm, although there have been acquired arteriovenous fistulas which do not in fact demonstrate connection to an artery. Surgically created AV fistulas work effectively because they: The procedure was invented by doctors James Cimino and M. J. Brescia in 1966. Before the Cimino fistula was invented, access was through a Scribner shunt,
