ECG/Dysrhythmias Top Rated Document EXAM 1 1 SLO’s 1. Relate electrocardiogram changes to common cardiac problems. 2. Discuss conduction system and electrocardiographic monitoring in pediatric and adult clients. 3. Introduction to assessment of normal and abnormal cardiac rhythm and appropriate treatment in pediatric and adult clients. 4. Compare and contrast nursing and collaborative management of pediatric and adult clients with common dysrhythmias. 5. Discuss nursing management of pediatric and adult patients with central venous access. Conduction System of the Heart • SA Node (Sinoatrial Node): located in the right atrium near the entrance of the superior vena cava. Natural pacemaker of the heart. Initiates all heart beat and determines heart rate. • AV Node (Atrioventricular Node): located on the other side of right atrium near AV valve. Gateway to the ventricles. Delay passage of electrical impulses to ventricles to ensure atria ejected all blood into ventricles before they contract. • AV Bundle (Bundle of His) o Right and Left Bundle Branches: conduct impulses to apex of heart • Purkinje Fibers: ventricle myocardium Electrocardiogram (ECG) • Detects electrical activity of heart • Components of an ECG waveform o P wave Atrial depolarization o P-R interval Onset of atrial depolarization to onset of ventricular depolarization o QRS complex Ventricular depolarization o ST segment
