In this chapter students will be able to: Describe the anatomy and physiology of the heart, explain the conduction system of the heart, describe the basic patterns of an electrocardiogram (ECG), identify the components of an electrocardiograph and what each does,. | 21 Electrocardiography and Pulmonary Function Testing 21- Learning Outcomes 21.1 Describe the anatomy and physiology of the heart. 21.2 Explain the conduction system of the heart. 21.3 Describe the basic patterns of an electrocardiogram (ECG). 21.4 Identify the components of an electrocardiograph and what each does. 21- Learning Outcomes (cont.) 21.5 Explain how to position the limb and precordial electrodes correctly. 21.6 Describe in detail how to obtain an ECG. 21.7 Identify the various types of artifacts and potential equipment problems and how to correct them. 21- Learning Outcomes (cont.) 21.8 Identify how the ECG is interpreted. 21.9 Identify common arrhythmias. 21.10 Summarize exercise electrocardiography. 21.11 Explain the procedure of Holter monitoring. 21.12 Describe forced vital capacity. 21- Learning Outcomes (cont.) 21.13 Describe the procedure of performing spirometry. 21.14 Describe the procedure for obtaining a performing peak . | 21 Electrocardiography and Pulmonary Function Testing 21- Learning Outcomes 21.1 Describe the anatomy and physiology of the heart. 21.2 Explain the conduction system of the heart. 21.3 Describe the basic patterns of an electrocardiogram (ECG). 21.4 Identify the components of an electrocardiograph and what each does. 21- Learning Outcomes (cont.) 21.5 Explain how to position the limb and precordial electrodes correctly. 21.6 Describe in detail how to obtain an ECG. 21.7 Identify the various types of artifacts and potential equipment problems and how to correct them. 21- Learning Outcomes (cont.) 21.8 Identify how the ECG is interpreted. 21.9 Identify common arrhythmias. 21.10 Summarize exercise electrocardiography. 21.11 Explain the procedure of Holter monitoring. 21.12 Describe forced vital capacity. 21- Learning Outcomes (cont.) 21.13 Describe the procedure of performing spirometry. 21.14 Describe the procedure for obtaining a performing peak expiratory flow rate. 21.15 Describe the procedure for performing pulse oximetry testing. 21- Introduction Patients often have cardiovascular or respiratory problems Medical assistant Perform screening and/or diagnostic testing Understand the anatomy and physiology of the heart and respiratory system 21- The Medical Assistant’s Role Electrocardiography Graphic recording of the electrical impulses of the heart Uses Evaluate symptoms of heart disease Check effectiveness or side effects of medications General examination 21- The Medical Assistant’s Role (cont.) Pulmonary function tests Measure and evaluate a patient’s lung capacity and volume Uses Help detect and diagnose pulmonary problems Monitor respiratory disorders Evaluate effectiveness of treatments 21- Anatomy of the Heart Muscular double pump Right – receives blood from the body, sends it to the lungs Left – receives blood from the lungs, sends it out to all parts of the body Four chambers Two atria Two
