True or False: Vtach can come with or without a pulse. - CORRECT ANSWER True How do you treat Vtach? - CORRECT ANSWER cardioversion or amiodarone if there's a pulse, if there's not a pulse start CPR What is indicative of Vfib? - CORRECT ANSWER chaotic quivering, upside down Vs How do you treat Vfib? - CORRECT ANSWER BLS/CPR and a defibrillator What is indicative of a 1st degree AV block? - CORRECT ANSWER 1 p wave, 1 QRS, but the PR interval is greater than .2; It will look exactly like normal sinus rhythm but the PR interval is prolonged What is indicative of a 2nd Degree Block: Wencheback (Type 1)? - CORRECT ANSWER prolonging the p wave until the QRS drops How do you tell the difference between Wencheback and a 3rd degree block? - CORRECT ANSWER check the R to R; if it's regular then it's a 3rd degree and if it's irregular then it's a 2nd degree Wencheback What is indicative of a 2nd degree: Mobitz (Type 2) - CORRECT ANSWER P and QRS intervals are constant but have a few extra p waves with no QRS complex behind it What is indicative of a 3rd Degree Block? - CORRECT ANSWER P waves and QRS are not talking to each other at all and are all irregular, if you measure nothing will measure the same r/t intervals between R to R What rhythm indicates a dying heart? - CORRECT ANSWER idioventricular rhythm What is indicative of an idioventricular rhythm? - CORRECT ANSWER the ventricle is doing all the work. There is no p wave, the qrs complex is wide and the heart rate is very slow (20-30 bpm) What is pulseless electrical activity? - CORRECT ANSWER rhythm is present on the monitor but the patient is pulseless. It doesn't matter if they have a rhythm, if there's no pulse ALWAYS START CPR Pace spike before the P wave - CORRECT ANSWER Atrial Pacing Pace spike before the qrs complex - CORRECT ANSWER V paced Pace spike before p and qrs complex - CORRECT ANSWER AV paced What is failure to sense? - CORRECT ANSWER the pacer fires in the middle of the patient's intrinsic heart beat, usually before the qrs complex or on/before the t wave What is failure to capture? - CORRECT ANSWER the pacer failing to cause a heart contraction; indicative of a long pause then a pacer spike with no rhythm behind it Ischemia Rhythm - CORRECT ANSWER Infarct Rhythm - CORRECT ANSWER How do you treat a first degree AV block? - CORRECT ANSWER no treatment is required, you just monitor until it resolves itself or progresses How do you treat a second degree av block Wencheback? - CORRECT ANSWER atropine if absolute bradycardia is present, pacemaker on standby. monitor patient's hemodynamic status How do you treat second degree av block type 2? - CORRECT ANSWER transvenous pacemaker, monitor closely for progression to third degree av block. atropine, isuprel, pacemaker, support blood pressure with fluid bolus, dopamine IV and epinephrine IV. r/o digoxin toxicity and hold all myocardial depressant medications True or False: a Third Degree AV block is a lethal dysrhythmia? - CORRECT ANSWER True How do you treat a third degree av block? - CORRECT ANSWER this needs to be paced immediately as blood perfusion is poor and cannot reach vital organs. Unifocal PVC - CORRECT ANSWER one focal point Multifocal PVC - CORRECT ANSWER more than one focal point Bigeminal PVC - CORRECT ANSWER every other beat is a PVC Trigeminal PVC - CORRECT ANSWER every third beat is a PVC Quadrigeminal PVC - CORRECT ANSWER Every fourth beat is a PVC Paired or Coupled PVCs - CORRECT ANSWER PVCs are occuring in pairs How do you treat PVCs? - CORRECT ANSWER only treat if they are symptomatic and you treat the underlying cause first. Lidocaine and/or atropine may be used if the underlying rate is too slow or may require chronic long term therapy What causes idioventricular rhythms? - CORRECT ANSWER sinus arrest or block, MI, or electrolyte imbalance How do you treat Idioventricular Rhythm? - CORRECT ANSWER atropine, dopamine, pacing What drugs are used for Vtach? - CORRECT ANSWER amiodarone, lidocaine, procainamide What causes Torsade de Pointes? - CORRECT ANSWER drugs that prolong myocardial repolarization and the qt interval. Hypokalemia, hypomagnesium, hypocalcemia, high grade av block Drugs for Vfib? - CORRECT ANSWER vasopressin, epinephrine, lidocaine, amiodarone Drugs for Asystole? - CORRECT ANSWER epinephrine, atropine How do you respond to ST segment change? - CORRECT ANSWER assess patient; apply O2; notify provider; 12 lead EKG; all of these steps need to occur simultaneously but if they cannot ALWAYS assess patient first True or False: ST segment elevated or depressed greater than 2mm is considered to be significant? - CORRECT ANSWER True Failure to capture - CORRECT ANSWER Failure to Sense - CORRECT ANSWER Atrial fibrillation - CORRECT ANSWER [Show More]
