Case Study, Chapter 22, The Cardiovascular SystemMary Hendricks, a 72-year-old Caucasian female, arrived yesterday in the EmergencyDepartment with reports of chest pain and difficulty breathing. Mary reported a 50+ year historyof smoking one pack of cigarettes a day and chronic high blood pressure. While she was in theED, Mary was diagnosed with a heart attack (myocardial infarction). Mary was admitted to thetelemetry floor of the hospital, and her telemetry monitor has continued to show a pattern ofslowed conduction through the heart, resulting in an abnormally low heart rate of 45 beats perminute. (Learning Objectives 3, 5, 7, 8)1. Describe how the path of blood flow through the heart differs from blood flow to the heart.2. Describe the major factors in the regulation of blood pressure.3. It is determined that Mary's heart attack most likely obstructed blood flow to the right coronaryartery (RCA). Describe how the lack of blood flow to this artery might play a role in her low heartrate.III!!!

The Importance of the Electrocardiogram and Holter Monitor in the Cardiovascular System Instructions The standard EKG consists of 10 sensors that record 12 leads of the heart’s electrical activity from different angles, allowing for a thorough three-dimensional interpretation of its activity. This is transmitted by the electrodes to the equipment to be interpreted and is used to diagnose cardiac medical conditions. In case of an abnormal EKG, the second step would be to use a Holter monitor. Questions Where will you place the electrodes when performing and EKG? Why? What are the different lead types, connections, and placements? When you conclude an EKG, what are the different components that you need to observe and confirm before you disconnect the patient? Can you explain the difference between normal, abnormal, and artifacts? What is a Holter monitor? Under what circumstances would one be ordered for a patient? How do you use a Holter monitor? Educate a patient: What you…
