cardiac assessment
Show Answers:

  1. Tachycardia is _ BPM
  2. Bradycardia is _ BPM
  3. Hemorrhage & dehydration cause a decrease in ____?
    Circulation blood volume & decreased SVR
  4. right heart failure
    blood backs up into the systemic circulation
  5. left heart failure
    blood backs up into the pulmonary circulation
  6. What causes first S1 heart sound?
    During ventricular diastole the atrioventricular (mitral & tricuspid) valves open & blood flows from atria to ventricles
  7. What causes S2 heart sound?
    During systolic phase, semilunar (aortic & pulmonic) valves open & blood flows form ventricles to aorta & pulmonary arteries.
  8. Cardiac enzymes
    creatine kinase, cardiac troponins I & T
  9. Formula for cardiac output
    CO = SV x HR
  10. Supraventricular dysrhythmias
    abnormal impulses originating above ventricles that have abnormal P waves
  11. P wave
    electrical conduction through atria
  12. PR interval
    AV to bundle of HIS to Purkinje
  13. QRS complex
    impulse through ventricles
  14. QT interval
    ventricular depolarization & repolarization
  15. conduction of heart pathway
    SA node > AV node > Bundle of His > Purkinje fibers
  16. How body adapts to hypovolemia?
    increases heart rate, peripheral vasoconstriction to increase volume of blood returned to heart thereby increasing cardiac output
  17. Left sided heart failure s/s
    fatigue, breathlessness (often at rest), dizziness, confusion, crackles, hypoxia, cough, paroxysmal nocturnal dyspnea
  18. Right sided heart failure s/s
    weight gain, distended neck veins, hepatomegaly, splenomegaly, dependent perepheral edema
  19. CK lab values
    • Male: 55-170
    • Female: 30-135
  20. Paroxysmal Supraventricular Tachycardia
    sudden rapid onset of tachycardia origination above AV node. Can be caused by excitement, fatigue, caffeine, smoking,etc.
  21. Life threatening rhythms
    ventricular tachycardia & ventricular fibrillation
  22. Cardiac Index
    • more precise measure of cardiac output
    • takes into account tissue perfusion & client's body surface area
    • Normal range is 2.5-4.0 per m2
