1:1? Yes No Ventricular pacing [pacing spike before the QRS only] 1:1? Yes No Demand pacing [heart rate is higher, pacemaker fires only if there is a delay in spontaneous activity]? Yes No Automatic internal defibrillator (IAD)? No Yes Has client felt it fire? No Yes, when _________________
Ectopic Beats: Ventricular premature beats (VPB, PVC) [an early, wide QRS, extra beat originating in the ventricle] Bigeminy [every other beat is a VPB] Trigeminy [every 3rd beat is a VPB] Quadrigeminy [every 4th beat is a VPB] Premature atrial beats (PAB, PAC) [an early, narrow QRS, extra beat originating in the atria, P wave shape may be different] Premature junctional beats (PJB) [an early, narrow QRS, extra beat originating above the A-V node, no P wave]
Lethal dysrhythmias: Ventricular escape rhythm (also called idioventricular) [wide QRS complexes, HR @ ventricular intrinsic rate, 30 - 40] Ventricular tachycardia [wide QRS, tachycardic rates, minimal cardiac output due to ineffective pumping, cannot sustain life] Ventricular fibrillation [erratic line, ventricles are quivering, no pumping action, cardiac output is 0]
*A fib with rapid response (HR > 100) increases myocardial oxygen needs and risk of LV failure is high, also high risk for PE .
**Previously called Wenckebach. ***Mobitz II second degree and third degree block can result in life threatening bradycardia....
