significance; S/S severe bradycardia then use atropine) 2 nd degree AV block Type II: PR interval constant long, multiple P blocks/ multiple QRS drops) (TX: depends; no clinical S/S then no clinical significance; S/S severe bradycardia then use atropine) 3 rd degree AV block: no relationship btw P and QRS (TX: pacemaker) 15. Ventricular Tachycardia: Wide QRS, regular (“McDonalds”) Monomorphic; polymorphic (treated as VFib) (FYI) With pulse; without pulse more dangerous (TX: shock/defibrillate, maintain airway) 16. Ventricular fibrillation: irregular & chaotic; no pulse; no cardiac output (TX: shock/defibrillation to return blood circulation & pulse) 17. Management of dysrhythmia: Bradycardia, tachycardia a) Cardioversion (unstable supraventricular tachy, A fib, VT mono, VT with a pulse) (synchorized cardioversion) - TX pace back to sinus rhythm; lower E b) Defibrillator (VT pulseless, VFib=VT polymorphic) (unsynchorized cardioversion=shock) - TX for life-threatening/VT pulseless; higher E c) AED 4 possible cardiac arrest rhythma: VFib, VT pulseless, asystole, PEA (Asystole and PEA no shock and no antiarrhythmics; no pulse) 18. Pacemaker and ICD nursing care
