Diagnostic Tests and Procedures CV

auscultation physical examination method of listening to sounds in the body with the aid of a stethoscope
bruit noise, an abnormal heart sound caused by turbulence within
gallop an abnormal heart sound that mimics the gait of a horse; related to abnormal ventricular contraction
electrocardiogram (EKG, ECG) electrical picture of the heart represented by positive and negative deflections on a graph labeled with the letters P Q R S T and corresponding to events of the cardiac cycle
stress electrocardiogram an ECG of the heart recorded during the induction of controlled physical exercise using a treadmill or bike(ergometer). good to detect ischemia and infarction
Holter ambulatory monitor portable ECG worn by patient that monitors electrical activity of the heart over 24 hours - good to find periodic abnormalities
intracardiac electrophysiological study (EPS) invasive procedure involving placement of catherter-guided electrodes within the heart to evaluate and map the electrical conduction of cardiac arrhythmias. intracardiac catheter ablation can be done at the same time to treat arrhythmia
intracardiac catheter ablation use of radiofrequency waves sent through a catheter within the heart to treat arrhythmias by selectively destroying myocardial tissue at sites generating abnormal electrical pathology
magnetic resonance angiography (MRA) imaging of the heart and blood vessels for evaluation of pathology
nuclear medicine imaging of the heart radionuclide organ imaging of the heart after administration of radioactive isotopes to visulaize structures and analyze function
myocardial radionuclide perfusion scan scan of the heart made after an intravenous injection of an isotope that is absorbed by myocardial cells in proportion to blood flow throughout the heart
myocardial radionuclide perfusion stress scan nuclear scan of the heart taken after the induction of controlled physical exercise via treadmill/bike. or giving a drug that produces the effect of exercise strss in patients unable to ambulate
positron emission tomography (PET) scan of the heart nuclear isotopes and computed tomography techniques to produce perfusion (blood flow) images and study the cellular metabolism of the heart; @ rest or w/ stress
radiology x ray imaging
angiography xray of a blood vessel after injection of contrast medium
angiogram record obtained by angiography
coronary angiogram xray of the blood vessels of the heart
arteriogram xray of a particular artery
aortogram xray of the aorta
venogram xray of a vein
cardiac catheterization introduction of a flexible, narrow tube (catheter) through a vein/artery to withdraw a sample of blood, measure pressures within the heart chambers/vessels and inject contrast media for fluoroscopic radiography & cine film imaging of chambers
left heart catheterization xray of the left ventricular cavity and coronary arties
right heart catheterization measurement of oxygen saturation and pressure readings from the right side of the heart
ventriculogram an xray visualizing the ventricles
stroke volume (SV) measurement of the amount of blood ejected from a ventricle in one contraction
cardiac output (CO) measurement of the amount of blood ejected from either ventricle of the hear per minute
ejection fraction measurement of the volume percentage of left ventricular contents ejected with each contraction
sonography sonographic imaging
echocardiography (ECHO) recording of sounds waves through the heart to evaluate structure and motion
stress echocardiogram echocardiogram of the heart during excercise - good to detect ischemia or infarction
transesophageal echocardiogram (TEE) echocardiographic immage of the heart after placement of an ultrasonic transducer at the end of an endoscope inside the esophagus
doppler sonography ultrasound technique to evaluate blood flow to determine the presence of a deep vein thrombosis (DVT) or carotid insufficiency or flow through heart/chambers/valves
intravascular sonography ultrasound images made after a sonographic transducer is placed at the tip of a catheter within a blood vessel - evaluates things like buildup of plaque
coronary artery bypass graft grafting portion of blood vessel from another part of the body to bypass an occluded coronary artery. bypass through heart/lung machine during surgery used
anastomosis opening; joining of two blood vessels to allow flow from one to another
endarterectomy incision and coring of the lining of an artery to clear a blockage caused by a clot or atherosclerotic plaque build up
transmyocardial revascularization (TMR) laser technique to open tiny channels in the heart muscle to restore blood flow. relieves angina . good option for patients not treated with angioplasty or coronary artery bypass
valve replacement sugery to replace a diseased heart valve with an artificial one (tissue or mechanical)
valvuloplasty repair of a heart valve
endovascular surgery interventional procedure performed endoscopically at the time of cardiac catheterization
angioscopy flexible fiberoptic angioscope/irrigation system/camera guided through a blood vessel to virtually assess the lesion
atherectomy excision of atheromatous plaque from within an artery using a device in a flexible catheter that cuts away tissue buildup
percutaneous transluminal coronary angioplasty (PTCA) treating the narrowing of a coronary artery by inserting a specialized catheter with a balloon attachment then inflating. most often includes placement of a stent
intravascular stent implantation of a device to reinforce the wall of a vessel and ensure patency. used to treat stenosis, a dissection, or to reinforce after angioplasty
defibrillation termination of ventricular fibrillation using an electrical stimulus by applying electrodes (external or internal-open heart surgery or an implant)
defibrillator device that delivers the electrical stimulus in defibrillation
cardioversion termination of tachycardia pharmaceutically of by delivering electrical energy
implantable cardioverter defibrillator (ICD) implanted battery operated device with rate sensing leads that monitor cardiac impulses and initiates an electrical stimulus as needed to stop ventricular fibrillation or tachycardia
pacemaker device to treat slow heart rates by electrically stimulating the heart to contract. usually implanted lead wires inserted into the heart do this
thrombolytic therapy dissolution of thrombi using drugs - ex streptokinase, tissue plasma activator (TPA)
