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...

Basic ECG interpretation Exam Review Solution 100% Accurate - The nurse should understand the conduction system of the heart, the process associated with rhythm monitoring through ECG interpretation, patient preparation for the 12-lead ECG, ECG findings, interpretation, and patient management with specific heart rhythm conditions. - The ECG uses electrodes attached to the patient's skin to record physiologic heart changes. - Four properties of heart cells, automaticity, excitability, con...

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...
