Telemetry Med Surg Exam 3 (Main Review) 100%correct

first degree AV block {Ans: Rate: Depends on underlying rhythm Rhythm: Depends on underlying rhythm P waves: Present PRI: >0.20 QRS: 0.06-0.10(12)}polymorphic ventricular tachycardia or tornadoes de pointes {Ans: Rate: 101-300 bpm Rhythm: Irregular P waves: None PRI: None QRS: > 0.12 sec. Variable amplitude. Appears to be twisting around a point. May be sustained or occur in burst (paroxymal )}monomorphic ventricular tachycardia {Ans: Rate: 101-250 bpm Rhythm: Regular P waves: Same as PVC PRI: Same as PVC QRS: > 0.12 sec. May be sustained or occur in burst (paroxymal VT)}notching in P wave indicates {Ans: atrial enlargement (p mitrale)}premature ventricular contraction {Ans: Rate: Depends on underlying rhythm Rhythm: Regular except for the PVCs P Waves: PVCs usually have no P waves or retrograde Ps. PRI: None associated with PVC QRS: PVC will be wide (>0.12) and aberrant compared with underlying rhythm. PVCs may be one shape or differ in shape due to multiple foci. Patterns: Bi and trigemeny, couplets and triplets}Step 2: calculating HR {Ans: most will print it mark on top = every 3 seconds count R waves during 6 seconds and multiply by 10}junctional escape beat {Ans: Rate: Depends on
