Introduction to Cardiovascular Procedure
• Specific testing that patients take base on the patient’s problem.
• The three that I will be discussing are the Cardiac Function Tests:
–Electrocardiography (ECG or EKG)
–Holter monitor
–Stress testing
ELECTROCARDIOGRAPHY
• Process of recording the electrical activity of the heart.
• This testing is use to measure the rate and regularity of heartbeats as well as the size and position of the chambers.
• Its also useful in diagnosis of abnormal cardiac rhythm and heart muscular damage.
HOLTER MONITOR • A portable ECG monitor
worn by a patient at least 24hr to monitor the heart and pulse activity while the person is going through the activities of their daily living.
• This monitor is used on patient who experience chest pain and unusual heart activity during exercise and normal activities.
STRESS TESTING • Stress testing is also called an
exercise test or treadmill test. • A monitor for evaluating
cardiovascular fitness. • The patient is placed on a
treadmill or a bicycle and then subjected to steadily increasing levels of work.
• An EKG and oxygen levels are taken while the patient exercises.
• The test is stopped if abnormalities occur on the EKG.
