Electrocardiogram (ECG) correct answer: Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) correct answer: Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? correct answer: Only monitors Straight line when machine is turned on but not connected to the patient correct answer: Isoelectric = no current ...

Cardiac Telemetry Exam 56 Questions with Verified Answers Normal Conduction System - CORRECT ANSWER -SA Node = Primary Pacemaker of the Heart, rate of 60-100 bpm -Internodal Pathways = Pathways connecting SA Node and AV Node -AV Node = Backup pacemaker, rate of 40-60 bpm -Bundle of His = splits nerve fibers down Left & Right Sides, His-Purkinje is conduction system of heart -L & R Bundle Brancehs = lead to left & right of the myocardium -Purkinje Fibers / Network = ends of the muscle, la...

What are cardiac dysrhythmias? CORRECT ANSWER abnormal rhythms of the heart's electrical system that can affect its ability to effectively pump oxygenated blood throughout the body What are the two questions you ask yourself when you have a patient with a dysrhythmia? CORRECT ANSWER 1. Is the patient symptomatic? (diaphoresis, light headed, unresponsive, decreased LOC, decreased BP, tachy/brady) 2. Is the heart going to wear out keeping this up? Electrical changes in cardiac cells prim...

What are the 6 parts of the cardiac conduction cycle? correct answer: -SA node -Internodal pathways -AV node -Bundle of His -R and L bundle branches -Purkinje fibers What is the SA node? correct answer: -Small cluster of cells located in the upper R atrium *-Pacemaker of the heart* What are internodal pathways? correct answer: Impulses sent by the SA node that travel through the atrial muscle fibers via the intra-atrial pathways Allows for simultaneous depolarization and contra...
