  32. The first heart sound (S1) comes from what closing?
    Mitral valve followed by the Tricuspid valve
  33. The second heart sound (S2) comes from what closing?
    The aortic valve followed by the pulmonic valve
  34. The third heart sound (S3) comes from what?
    It is the result of the rapid filling of the left ventricle following the opening of the mitral valv e.
  35. What does it mean pathophysiologically to have an S3?
    physiological in young people or regular population with high flow states

    pathological in patients with CHF and dilatation in ventricles
  36. The fourth heart sound (S4) comes from what?
    blood being forced into a stiff noncompliant left ventricle
  37. A patient with an S4 could be from what pathologies?
    HTN, Ischemia, outlet structures, or hypertrophic or infiltrated my case.
  38. Most murmurs are louder in the ____ position
    Recumbent Due to increased venous return
  39. Mitral murmurs are best heard mitral thrills our best felt when the patient is on the ____ side
    Left side. This brings the apex of the heart closer to the chest wall.
  40. Normally the point of maximal impulse is palpated along the ____ line.
    Mid clavicular line
  41. Pulsus altertans is characterized by a regular rhythm with a ____ and ____
    Alternating strong and weak ventricular contractions. It is thought to be the result of alternation in the left ventricular stroke volume.
  42. Thrills are palpable _____.  How do you feel for a thrill?
    Murmurs. Because the junction of the fingers in the hand is more sensitive to low-frequency events and then the fingertips, their best felt with the palm of the hand.
  43. Where is the thrill for aortic stenosis Palpated ?
    Crosses the palm of the hand toward the right of the neck
  44. Where is the thrill of pulmonicstenosis felt?
    The location crosses the palm of the hand toward the left of the neck.
  45. Where is the thrill of ventricular septal defect felt?
    The location of thrill for VSD is located third and fourth intercostal space, left sternal border.
