Diagnostic tests for the cardiovascular system
Diagnostic tests for the cardiovascular system
----- Meeting Notes (2/17/15 19:37) -----eluminate the importance of the cardiovascular system
diagnostic tests allow for a proper diagnosis and potential treatment for this system1The Cardiovascular System
Function: Circulates blood throughout body
Organs: Heart and blood vessels
----- Meeting Notes (2/17/15 19:37) -----What is the CV system?
purpose is to circulate blood throughout the body
2 organs associated... Heart=pump that moves the blood through the vessels
blood vessels= highways to bring blood to and away from the heart
2The Heart
----- Meeting Notes (2/17/15 19:37) -----this slide shows the heart in an anatomical position
CV system (circulatory system) works in one constinuous motion--pump the blood, the heart is dependent on electical activity that tells the heart to pump the atria or ventricles
heart =very intricate organlots of opportunities to have many complications with the heart
may need diagnostic testing to diagnose the problem3Electrical Activity of the Heart
This slide shows the electrical pathway of the heart. The electrical activity begins in the SA node triggering the L &R atria to contract. It also sends signals to the AV where the signals are continued down to the L&R ventricles .promoting ventricular contractions4Diagnostic Tests Echocardiography
Holter Monitor
Stress Test
Echo cardia graphy5EchocardiographyUses sound waves (ultrasound technology) to view the structure of the heartDetectsAbnormal heart valvesAbnormal heart rhythmsCongenital heart disease (ie. Ventricular septal defects)Damage to the heartInflammation of the pericardiumSource of blood clotTypes of EchocardiogramsTransthoracic echocardiogram (TTE)Transesophageal echocardiogram (TEE) More invasive
----- Meeting Notes (2/17/15 19:37) -----good for detecting abnormalities in the heart structure, which may be due to congenital heart disease such as...hole in the heart
noninvasively observe the structure of the heart by placing the ultrasound probe on the chest of the patient
involves an ultrasound probe that goes in the mouth down the esophagus of a patient6Holter MonitorRecords the electrical activity and rhythm of the heart over an extend period of timePortable DetectsPalpitationsArrhythmiasAtrial fibrillation or flutterHeart irregularities that cannot be detected by an electrocardiogram (ECG)
electrodesEcg=snapshot of a heart rhythm=> cant always record the irregularity----- Meeting Notes (2/17/15 19:37) -----electrodes 7Stress TestMonitors the blood pressure and electrical activity of the heart under stressful conditionsUse electrocardiography to monitor the rate and rhythm of the heartDetectsIschemia during exertionLocation of myocardial Infarction TypesExercis/Treadmill stress testDobutamine/Regadenoson stress testStress echocardiogramNuclear stress test
----- Meeting Notes (2/17/15 19:37) -----Unique ischemia= lack of oxygenated bloodinfarction=death of cells
localize myocardial infarction
simulate exertion on the heartCardiologist 8
