Dysrhythmia Flex Education STUDY GUIDE |100% Correct| ___ ___ is the amount of blood pumped by the LV with each contraction or beat. *Ans*stroke volume ___ ___ is the number of times the LV contracts in 1 minute; the normal rate is 60-100 *Ans*heart rate ___ ___ occurs before normal firing of SA node usurping the normal pacemaker and can originate from atrial, junction, or ventricles. *Ans*premature beat (PAC, PJC, PVC) ___ ___ occurs from one of the lower pacemaker sites due ...

sinus bradycardia correct answer: -less than 60 beats per minute -P wave in front of every QRS -PR--0.12 to 0.20 -QRS less than 0.12 -if symptomatic--atropine, pacemaker sinus tachycardia correct answer: -treat underlying cause (fever, pain, etc.) Sinus Arrhythmia correct answer: irregular with breathing--HR increases with inspiration and decreases with expiration -only treat if hemodynamically compromised--atropine SA block correct answer: -dropped interval/pause -if hemodyna...

Cardiac Telemetry EXAM | questions and answers 2023/24 Normal Conduction System -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, last escape pacemaker...

Normal PRI interval - Answer 0.12-0.20 Normal QRS interval - Answer 0.11 or less What does the P wave represent? - Answer Atrial depolarization What does the QRS complex represent? - Answer Atrial repolarization and ventricular depolarization Q wave indicates what? - Answer Dead myocardial tissue. Always a negative deflection What is the natural pacemaker of the heart? - Answer SA node 3 types of pacemakers - Answer 1) single (either RA or RV) 2) dual chamber (RA and LV) 3) bi-ventricu...

junctional tachycardia - ️️-Rate: 100 to 180bpm Regularity: regular P-wave: inverted, absent, or occur after the QRS-complex PR-interval: short or absent -control rate if symptomatic--beta blockers, CCB, amiodarone -if rate >150--vagal stimulation, adenosine, beta blockers, CCB, amiodarone, check dig level -no cardioversion atrial flutter - ️️-Sawtooth pattern -250 to 350 beats -PRI cant determine** -QRS less than .12 -need to control ventricular rate and convert the rhyth...

First Degree Atrioventricular Heart Block correct answersprolonged PR interval-measures the time required for an impulse to travel from the SA to the AV node. PRI longer than 0.20 Second degree AV block Type I correct answersprogressive prolongation of PRI, gradual shortening of R to R intervals P wave not followed by a QRS wave a pause with an R to R interval less than the sum of two P to P intervals first conducted atrial impulse after the pause shows a shorter or normal PRI ...
