  1. Normal EKG
    • P wave- atrial Depolarization
    • PR - interval - time required for conduction to go from SA node to AV node
    • QRS complex - atrail repolarization and ventricle depolarization
    • ST segment - delay before repolarization of ventricle, useful in assessing mycardial ischemia
    • T wave - ventricular repolarization
  2. Cardiac Output
    • The amount of blood pumped out of the heart through the aorta each min
    • Normal adult 5.6 (female 10% less)
    • CO_ SV x HR
  3. Stroke Volume
    Amount of blood ejected from the ventricles each contraction
  4. Venous Return
    The amount of blood returning to the right atrium each minute similar in volume to cardiac output

    • Related to another medical Problem
    • Kidney disease
    • Kidney failure
  7. Pathophysiology of HNT
    • An increase prssure load fon the left ventricle leading to left ventricular hypertropy
    • Increased dependence on ative "atrial kick" for left ventricle filling. IF inadequate L ventricle filling, stroke volume is decreased, leading to symptoms of decreased CO and pumonary congrestion
