Critical Nursing Cardiac Dysrhythmias Advanced Questions and Answers 2024 1. What is the pacemaker of the heart normally? Answer: SA Node. 2. Where does the SA node originate? Answer: Upper right atrium. 3. What is the pathway of conduction in the heart? Answer: SA node -> atria -> AV node -> bundle of his -> bundle branches -> purkinje fibers -> ventricles. 4. What does stimulation of the vagus nerve cause? Answer: Decreased firing of the SAnode and slowed impulse...

Define Electrocardiograph (ECG) Electrocardiograph is a machine which is used to assess electrical activity of the cardiac system by using electrodes placed on a patients body.

Basic Cardiac Rhythm Interpretation Advanced Exam Review Update A+ 1 / 22 P Wave Atrial Depolarization stim￾ulated by the firing of the SA node. Evaluate: consistent ap￾pearance and 1:1 relation￾ship with QRS complex. If not identical some, or all, may be atrial, but not SA node, in origin. IF >1 P-wave precedes QRS a heart block may be present. Basic Cardiac Rhythm Interpretation Advanced Exam Review Update A+ 2 / 22 PR Interval Impulse traveling time from the atriu...

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...
