Sinus tachycar- dia characteris- tics 10. sinus tachycar- dia treatment 11. atrial fibrillation characteristics 0.12-0.2 seconds 0.04-0.12 seconds 0.34-0.43 seconds originates in SA node -normal intervals - will walk out SA node in control, rate below 60, normal intervals hypoxia, hypothermia, sleep, athletes, medications Atropine 0.5 mg IV push fever, anemia, hypotension, PE, MI SA node in control, rate above 100, normal intervals vagal maneuvers - beta blockers, Ca channel blockers SA node is not in control, rate is determined by AV node response - random cells are firing (ectopic foci) - rate is often high, rapid ventricular response (RVR) - does not walk out 12. cardiomyopathy, pericarditis, HTN, CAD, cardiac surgery Telemetry- 372 Exam 1 2 / 8 atrial fibrillation causes 13. atrial fibrillation treatment 14. atrial flutter char- acteristics 15. atrial flutter caus- es 16. atrial flutter treat- ment 17. supraventricular tachycardia characteristics 18. supraventricular tachycardia causes 19. supraventricular tachycardia treatment 20. Junctional rhythm characteristics 21. junctional rhythm causes - beta blockers, Ca channel blockers, digoxin - cardioversion: evaluate for clots first with TEE - anticoagulants SA node is not in control! - one random cell is firing rapidly in the atria, the rate is determined by the AV node response - does not walk out acute MI, chest surgery, mitral valve disease, digoxin tox- icity same as AFib! - beta blockers, Ca Channel blockers, digoxin - cardioversion - anticoagulant SA node is not in control, one cell is firing rapidly, rate is determined by AV node response - QRS can be narrow or wide infection, fever, hypovolemia, hypoxia, ischemia, drug tox- icity adenosine - beta blockers, Ca channel blocker AV node is in control - inverted or no P wave - walks out MI, HF, Ca channel blockers, beta blockers, digoxin 22. atropine, external pacemaker Telemetry- 372 Exam 1 5 / 8 42. ventricular tachy- cardia character- istics 43. ventricular tachy- cardia causes 44. ventricular tachy- cardia treatment neither SA or AV controls the heart. One ectopic focus is firing in the ventricle - looks like constant PVCs - a run of 3 or more PVCs coronary artery disease, MI, digoxin toxicity - with pulse: amiodarone, cardioversion-synchronized - without pulse: CPR, defibrillation, epi, vasopressin 45. ventricular fibril- lation character- istics neither SA or AV are in control, multiple ectopic foci are firing in the ventricle - coarse vs fine 46. ventricular fibril- lation causes acute MI, acidosis, drug toxicity, hemorrhage, hyper- kalemia 47. ventricular fibril- lation treatment CPR, defibrillation (within 2-3 mins of onset), epi, vaso- pressin, amiodarone 48. torsades charac- teristics for of ventricular tachycardia that "twists" along the base- line - can lead to Vfib - does not look uniform 49. torsades causes secondary to drug effects and electrolyte abnormalities, give magnesium 50. asystole charac- teristics no electrical activity 51. pulseless electri- cal activity leftover electrical activity in the heart makes it look like a beat but there is no pulse 52. normal sinus rhythm 53.
