    • Vagal inhibition
    • Increased SNS stimuli
    • exercise
    • anxiety/stress/fear
    • electrolyte imbalances
    • fever
    • meds that increase HR(atropine/epi/thyroid meds/bronchodilators)
    • caffine/alcohol/nicotine
    • PE
    • anemia
    • hypoxemia
    • hyperparathyroidism(increased Ca++)
  3. Does the pt have a P wave?
    yes
  4. What occurs to CO & BP
    • at first increases,
    • eventually ventricles don't have time to fill
    • leads to decreased perfusion
    • increased O2 demand
  5. How is tachycardia treated
    • treat cause
    • may use valsalva to decrease HR
    • bedrest for hypotension/weakness
  6. What is a concern for pt w/tachycardia
    • fall risk due to

  7. What are some S/S of tachycardia
    • palpitations
    • chest pain(ischemia)
    • anxiuos
    • pale, cool skin
    • syncope
    • hypotension
    • weak/fatigue
    • orthopnea
    • decreased O2
    • urine output decreased(no perfusion)
  8. Tachycardia can lead to HF, what are some S/S of HF
    • dyspena
