1. 1. DIAGNOSTIC TESTS FOR THE CARDIOVASCULAR SYSTEM
2. 2. The Cardiovascular System Function: Circulates blood throughout body Organs: Heart and blood vessels
3. 3. The Heart
4. 4. Electrical Activity of the Heart
5. 5. Diagnostic Tests Echocardiography Holter Monitor Stress Test
6. 6. Echocardiography Uses sound waves (ultrasound technology) to view the structure of the heart Detects Abnormal heart valves Abnormal heart rhythms Congenital heart disease (ie. Ventricular septal defects) Damage to the heart Inflammation of the pericardium Source of blood clot Types of Echocardiograms Transthoracic echocardiogram (TTE) Transesophageal echocardiogram (TEE) More invasive
7. 7. Holter Monitor Records the electrical activity and rhythm of the heart over an extend period of time Portable Detects Palpitations Arrhythmias Atrial fibrillation or flutter Heart irregularities that cannot be detected by an electrocardiogram (ECG)
8. 8. Stress Test Monitors the blood pressure and electrical activity of the heart under stressful conditions Use electrocardiogram to monitor the rate and rhythm of the heart Detects Ischemia during exertion Location of myocardial Infarction Types Exercise stress test Dobutamine/Regadenoson stress test Stress echocardiogram Nuclear stress test
