Chapter 52 - Electrocardiography and pulmonary function testing. This chapter introduces you to the electrocardiograph instrument and how to administer an electrocardiogram. You will also learn how to apply electrocardiograph electrodes and wires, operate the instrument, and troubleshoot problems that can occur while recording the heart's electrical activity. | 52 Electrocardiography and Pulmonary Function Testing 52- Learning Outcomes 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. 52- Learning Outcomes (cont.) Explain how to position the limb and precordial electrodes correctly. Describe in detail how to obtain an ECG. Identify the various types of artifacts and potential equipment problems and how to correct them. 52- Learning Outcomes (cont.) Identify how the ECG is interpreted. Identify common arrhythmias. Summarize exercise electrocardiography. Explain the procedure of Holter monitoring. Describe forced vital capacity. 52- Learning Outcomes (cont.) Describe the procedure of performing spirometry. Describe the procedure for obtaining a performing peak . | 52 Electrocardiography and Pulmonary Function Testing 52- Learning Outcomes Describe the anatomy and physiology of the heart.

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 52- 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
