APEX EKG Test Questions And Answers Latest Top Score. EKG Grid - correct answer. Each small square (the smaller lighter boxes within the big bold boxes) represents 0.04 seconds Each larger square (the boxes within the bold lines) represents 0.2 seconds. Each large square has 5 small squares across SO 0.04 X 5 = 0.2 seconds The 6 Second Strip Method - correct answer. Least accurate, but quickest way to estimate rate especially in irregular rhythms EKG - correct ans...

Telemetry Exam 68 Questions with Verified Answers Cardiac conduction - CORRECT ANSWER ECG components - CORRECT ANSWER Heart auscultation - CORRECT ANSWER All people enjoy time magazine Aortic, pulmonic, Erb's point, tricuspid, mitral P wave - CORRECT ANSWER P wave= time for passage of the electrical impulse through the atrium causing atrial depolarization (contraction) Normal: 0.06-0.12 sec (remember, p for preteen: 6-12) What is a source of possible variation in P wave? - ...

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

Know how to measure the PR interval ( PRI) - From where the P wave begins until the beginning of the QRS complex. 0.12 to 0.20 seconds (3 to 5 small boxes) in adults, longer in elderly people. Know how to measure the QRS - From the end of the PR interval to the end of the S wave. 0.08 to 0.10 seconds. (2-2 1/2 boxes) Know the normal values for the PRI and the QRS - PRI = 0.12 - 0.20 or 3-5 boxes QRS = 0.08 - 0.10 or 2- 2 1/2 boxes

Cardiac Telemetry Questions and Answers(graded A) 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 pacemak...

What is the range for normal PRI? correct answers 0.12-0.20 (3-5 small boxes) What is the normal range for QRSI? correct answers <0.12 (3 small boxes) (0.06 to 0.10 seconds according to the pp) What is the normal range for QTI? correct answers 0.42 (Ch 7 pp, slide 39 says 0.32 to 0.5) What are the steps for rhythm interpretation? (Hint: Role Playing Really Makes Wendyll Dirty) correct answers 1). *R*:Regular or Irregular? 2). *P*:Is there a P wave for every QRS? 3). *R*:What is ...

EKG Academy Study Notes Latest Update. 1) Rhythm Regularity 2) Heart Rate 3) P wave morphology 4) P R interval or PRi 5) QRS complex duration and morphology The 5 steps of rhythm analysis should be followed when analyzing any rhythm strip. Analyze tracings in the following sequence. Carefully measure from the tip of one R wave to the next, from the beginning to the end of the tracing. A rhythm is considered "regular or constant" when the distance apart is either the same or varie...
