CARDIAC HEALTHSTREAM TELEMETRY EXAM Q & A 2023/2024 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, last...

5 lead electrode placement - go in intercostal space! *Smoke over fire, snow over grass, and brown in middle!* 6 steps of rhythm strip analysis - 1. determine if regular or irregular 2. calculate rate 3. evaluate the p & QRS waves 4. measure the PR interval 5. measure the QRS 6. interpret rhythm A-Fib etiology - - Advanced age - MI - CAD - Valvular disease - Congenital heart defects - Hyperthyroidism - Stimulant medication abuse A-Fib s/sx - u-"F" fibrillatory waves -Ø discern...

Pacemakers of the Heart correct answer: Sinoatrial (SA) node Atrioventricular (AV) node Bundle of His Bundle Branches Purkinje Fibers -SA node: p wave -SA node to AV node: PR segment -Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex -Repolarization of ventricles: T wave P wave correct answer: sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG AV nod...

Normal Conduction System -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, last escape pacemaker sites rate of 14-40 Tele Strip Paper -ANSWER -S...

Cardiac EKG Rhythms (Updated). Normal Sinus Rhythm Normal Sinus Rhythm ● Rate: 60-100 beats per minute ● Rhythm: Atrial and Ventricular Regular ● P Wave: Uniform in appearance, upright, normal shape, one preceding each QRS complex ● PR Interval: 0.12- 0.2 seconds ● QRS: 0.12 second or less. (If larger than 0.12- QRS is wide and there may be a bundle branch block) Sinus Bradycardia ● Rate: Less than 60 beats per minute ● Rhythm: Atrial and Ventricular Regular ● P Waves...

Normal Sinus Rhythm - NSR Rate: 60-100 bpm Regularity: Regular P Waves: Normal PR Interval: 0.12-0.20 s QRS Duration: 0.04-0.12 s QT Duration: 0.36-0.44 s Sinus Node - Sinus Node Problems: The SA node can: --Fire too slow (Sinus Bradycardia [SB]) --Fire too fast (Sinus Tachycardia [ST]) Sinus Bradycardia (SB) - Rate <60 bpm Etiology--SA node is depolarizing slower than normal, impulse is conducted normally --Normal PR interval and QRS interval --Once SA node fires, everythin...
