    the P-Waves are different and the PRI varies

    pacemaker switches from beat to beat, from SA node to atria and back
  12. what is a PAC
    • premature meets usually indicate irritability in the area of myocardium in which they arise

    • usually asymptomatic
    • indicates some degree of damage to the conduction system in the AV node
    • rate generally 60-100 (depends on underlying rhythm)
  25. 2nd degree heart block Wenckebach
    progressively lengthening PRI, until dropped beat occurs; irregular with grouped beating
  26. Classical 2nd Degree Heart Block
    the PRI is constant for conducted beats and there is 2 or more P-Waves for every QRS complex
  27. Third degree heart block
    • Medical Emergency
    • there is no constant PRI, P-Waves and QRS complexes are regular, but there is no relationship
    • Asynchronized pacing set to fire constantly regardless of the underlying
    • Atropine 0.5-1mg at bedside, admin O2, pacemaker

    • CPR
  39. Bundle Branch Block
    • QRS 0.12 or greater
    • impulse wil travel along unaffected branch and activate the ventricle normally but the impulse is delayed in reaching the other ventricle because it has to go down a different pathway, Makes the ventricles depolarize sequentially instead of together. You will see a wide QRS pattern with 2 peaks
  40. Asytole
    there is no electrical activity and has flat baseline
  41. ST Depression =
    Ischemia

    • nonsynchronized
    • 200,300,360 (check pulse between)
  46. Pacemaker terminology
    Capture
    the pacemaker has discharged an adequate electrical impulse and depolarization has occurred
  47. Pacemaker terminology
    noncapture
    • when a pacemaker spike fails to produce the desired effect (atrial or ventricular depolarization)
    • May result from: Low mA setting, Lead placement is in scarred tissue, or drifting of the lead wires away from the muscle wall
  48. Pacemaker Terminology
    Demand PAcing
    • the pacer is set to fire when the patient's heart rate falls below a set rate
    • Synchronous demand pacing means that a generated impulse occurs as needed basis
    • Asynchronous demand pacing is when the pacemaker is programmed to fire continuously at a fixed rate regardless of the underlying rhythm
  49. Pacemaker terminology
    Sense
    means the pacemaker is "set" to detect the patient's own heart rhythm
  50. pacemaker function depends on the programming sequence or settings, each one represented by a letter
    • 1st letter identifies the chamber being paced
    • 2nd letter identified the chamber in which the pacer can sense the patient's electrical activity
    • 3rd letter tells one what the pacer does in response to sensing patient's own electrical activity
    • 4th letter tells the sophistication of the pacer (may not have 4th letter)
    • A=Atrial, V=Ventricle, D=Dual, O=Nothing
  51. ICD is multifunctional, what does it provide?
    • Anti-tachycardic pacing
