chapter 6 common diagnostics test and procedures Flashcards
Angiography
therapeutic radiography of the heart and blood vessels
Automated external defibrillator AED
small compued-driven defibrilator that analyses pt rhythm, select the appropiate energy level, charges the machine and delivers a shock to the pt
Automatic implanted cardioverter defrivilator AICD
small defibrillator surgicaly implanted in the pt with risks of suddent cardiac death. detects and treats cardiac arrhythmias
Cardiac catherization
evaluattion of the heart vessels nd valves via injection of dye that shows up under radiology
Cardiopulmonary Resuscitation CPR
emergency procedure that provides manual external cardiac compression and sometimes artificial respiration
Cardioversion
restoration of normal sinus rhythm NSR by chemical or electrical means
Coronary artery bypass graft CABG
surgical creation of an alternate route for blood flow around the coronary obstruction
Defibrillation
Delivery of an electric shock with the goal of ending ventricular fibrillation and restoring SNR
Electrocardiography ECG, EKG
creation and study of graphic records (electrocardiograms) of electric currents originating in the heart
Event recorder
portable recording device that transmits heart rhythms by telephone to a central laboratory
Holter monitor
portable device worn by a pt during normal activities that records heart rhythm for 24 hrs
International normalized ratio INR
metod to check the prothrombin time PT monitors and adjust warfarin (coumadin) dosage in order to maintain balance between cllot prevention and eccesive bleeding
pacemaker
trigers mechanical contractions of the heart by emitting electrical discharges
Partial thromboplastine time PTT
Measures bood clotting time used to control heparin therapy
Percutaneous transluminar coronary angioplasty PTCA
for treating a narrowed coronary artery via inflation and deflation of a baloon on a double lumen catherer through the right femoral artery
