Telemetry Exam 39 Questions with Verified Answers,100% CORRECT

Telemetry Exam 39 Questions with Verified Answers Mechanical activity - CORRECT ANSWER follows electrical activity Purkinje fibers - CORRECT ANSWER Av goes to bundle of his to where? Lead placement - CORRECT ANSWER PR - CORRECT ANSWER 0.12-0.2 seconds QRS - CORRECT ANSWER 0.04-0.12 QT - CORRECT ANSWER 0.34-0.43 ST - CORRECT ANSWER 0.12 T - CORRECT ANSWER 0.16 p wave - CORRECT ANSWER atrial contraction QRS complex - CORRECT ANSWER ventricular contraction T wave - CORRECT ANSWER ventricular repolarization normal sinus rhythm - CORRECT ANSWER -normal intervals -rate 60-100 -will walk out Sinus Bradycardia - CORRECT ANSWER SA is in control rate 60 bpm normal intervals walks out sinus tachycardia - CORRECT ANSWER SA is in control rate higher than 100 bpm normal intervals walks out atrial fibrillation - CORRECT ANSWER SA not in control random cells are firing in atria rate determined by AV node -rate often high: Rapid ventricular response does not walk out blood clot - CORRECT ANSWER biggest concern for fibrillation? atrial flutter - CORRECT ANSWER Sa not in control one random cell firing rapidly rate determined by AV node "saw tooth pattern" does not walk out Supraventricular tachycardia - CORRECT ANSWER SA not in control one cell firing rapidly rate determined by AV QRS can be narrow or wide may look like sinus tach, but its higher Junctional Rhythm - CORRECT ANSWER Av in control (ventricles working) rate: 40-60 bpm inverted or no P wave walks out Accelerated Junctional Rhythm - CORRECT ANSWER Av is in control No p wave faster than normal rate greater than 60 walks out beta blockers - CORRECT ANSWER heart blocks similar cause First degree heart block - CORRECT ANSWER -slow electrical conduction through atria *PR greater than 0.2* rate can be slow or normal QRS and QT the same (usually not treated) Second degree (Wenckebach) - CORRECT ANSWER -slow conduction between SA and AV gets progressively longer until a QRS drops second degree type 2 - CORRECT ANSWER slow conduction between SA and AV node is consistent until a QRS is dropped third degree heart block - CORRECT ANSWER -no relationship between SA and AV node -P wave and QRS have no correlation *20-30 HR* only way to fix this? pacemaker bundle branch block - CORRECT ANSWER -delayed conduction of ventricle rather than atria -causes a wider QRS complex -left or right (usually with additional rhythm) premature atrial contraction - CORRECT ANSWER Sa node fires prematurely early beat often called "NS with PAC" premature ventricular contraction (PVC) - CORRECT ANSWER ectopic focus in the ventricle fires causing contraction -random QRS without a P wave -unifocal= looks the same -multifocal= looks different bigeminy - CORRECT ANSWER pattern of PVS, occuring every second beat (PVCS arent true beats) trigeminy - CORRECT ANSWER pattern of PVC's occur every third beat atrial pacemaker - CORRECT ANSWER works as SA node looks like a spike before a P wave ventricular pacemaker - CORRECT ANSWER working as AV node looks like line before QRS complex (P wave can be present) atrioventricular pacemaker - CORRECT ANSWER works as both SA and AV node looks like a line before both the P and QRS wave leads - CORRECT ANSWER never put what on top of a pacemaker? ventricular tachycardia - CORRECT ANSWER neither SA or AV controlling the heart one ectopic foci is firing in the ventricles looks like constant PVC's officially more then 3 PVC's ventricular fibrillation - CORRECT ANSWER neither SA or AV in control multiple ectopic foci are firing in the ventricle coarse vs fine torsades - CORRECT ANSWER specific form of v-tach but "twists" along the baseline -can lead to v-fib -does not look uniform *must give magnesium* asystole - CORRECT ANSWER flat line Pulseless Electrical Activity (PEA) - CORRECT ANSWER heart not actually pumping leftover electricity in the heart
