Cardiovascular Diagnostic procedures Flashcards
Insertion of a small tube (catheter) through a vein or artery, usually of an arm (brachial approach) or leg (femoral approach); the tube is threaded through a blood vessel until it reaches the heart; used to inject a contrast medium for imaging, diagnosing abnormalities, obtaining blood samples, or measuring pressure within the heart, and often includes interventional procedures, such as angioplasty and atherectomy
cardiac catherization
Battery of blood tests performed to determine the presence of cardiac damage
cardiac enzyme studies
Ultrasound technique that records blood flow velocity (speed) to image major blood vessels (arteries or veins in arms, neck, legs, abdomen) to detect obstructions caused by atherosclerotic plaques in patients at risk for a stroke; also called ultrasonography using sound pitch
Doppler Ultrasonography
Ultrasound technique used to image the heart and evaluate how the heart’s chambers and valves are working and to diagnose and detect pathological conditions
echocardiography
(echo)
Creation and study of graphic recordings (electrocardiograms) produced by electrical activity generated by the heart muscle; also called cardiography
electrocardiography (ECG, EKG)
Monitoring device worn by a patient that records electrocardiograph readings (usually 24 hours) on a portable recorder while the patient conducts normal daily activities smaller, portable recording devices are now being used and are taped to the chest or worn on the wrist.)
holter monitor
Electrocardiography (ECG) taken under controlled exercise stress conditions (typically using a treadmill) while measuring oxygen consumption
ECG that uses a radioisotope to evaluate coronary blood flow
stress test (nuclear)
Blood test that measures protein released into blood by damaged heart muscle (not skeletal muscle) and is a highly sensitive, specific indicator of recent myocardial infarction (MI)
troponin I
Surgery that opens a blocked artery by inflating a small balloon within a catheter to widen and restore blood flow in the artery
Angioplasty
Restoration of normal heart rhythm by applying an electrical countershock to the chest by using a device (defibrillator); also called defibrillation
cardioversion
defibrillation
Bypass surgery in which peripheral veins are removed, and each end of the vein is sutured onto the coronary artery to create new routes around narrowed and blocked arteries, allowing sufficient blood flow to deliver oxygen and nutrients to the heart muscle
coronary artery bypass graft
CABG
Device used to administer a defibrillating electrical shock to restore normal heart rhythm
defibrillator
Surgically implanted electrical device that continuously monitors and corrects potentially fatal arrhythmias by delivering low-energy shocks to the heart; also called implantable cardioverter defibrillator (ICD)
automatic implantable cardioverter-defibrillator
Portable computerized device that analyzes the patient’s heart rhythm and delivers an electrical shock to stimulate a heart in cardiac arrest
automatic external defibrillator (AED)
Surgical removal of the lining of an artery
endarterectomy
end-: in, within
arter: artery
-ectomy: excision, removal
Endarterectomy is a procedure to remove plaque from narrowed arteries an
