Question
Answer
allows study of the electrical activity going thru the heart   ECG  
🗑
In an ECG what is placed on the surface of the skin that picks up impulses of the heart?   Electrodes  
🗑
ECG is graphed on standardized paper or viewed by what type of scope?   Oscilloscope  
🗑
what letters represent one cardiac cycle?   P, Q, R, S, T waves  
🗑
a normal finding on the ECG graph is called what?   Normal sinus rhythm  
🗑
ECG is used to detect abnormal rates, ____, and _____ conduction   rhythm, impulse  
🗑
ECG detect abnormalities/changes caused by ___ to the heart.   damage  
🗑
Pre-op care: ECG   1) Tell the pt what to expect. 2) Painless procedure. 3) No special preparations is needed.  
🗑
Post op care: ECG   1)Remove from skin 2)No special care needed  
🗑
Summary of ECG uses   abnormal rhythm ie. a-fib, damege ie. MI, conduction exam ie. irregularity, abnormal rate ie. V-tach. Heart blocks  
🗑
a portalble device ECG machine   Holter monitor/Ambulatory ECG  
🗑
holter monitors provide continuous or intermittent monitoring for how many hours?   continuous, 24-48hrs  
🗑
how are holter monitors and ECGs similar in uses?   used to detect dysrhythmias  
🗑
what is the main difference in uses between holter and ECGs?   ECG's are to monitor abnormalities happening right now. Holter is for 24-48 hrs because the dysrhythmia may not be happening right now but happens infrequently  
🗑
When listening to a pt's apical you hear an irregular heart beat that returned to normal after 1 minute and remained regular. Which diagnostic test would you use and why?   Holter Monitor (you can use an ECG right there but it may not pick up the irregularity since it resolved). With an holter monitor it can happen again w/in 24 hours and can be recorded, and the pt can do normal activities w/o being admitted.  
🗑
Holter moniters are also used assess effects of ____ and for ____ purposes   medications, research purposes

🗑
Aside from computer scanning, how else can holter monitor results be sent for review?   transtelephonic: audio signal sent over telephone lines.  
🗑
Mrs. Gorcyca's main emphasis of Holter monitor are two things, name them:   pt. should not shower and push event button when symptomatic.  
🗑
what did Mrs. Gorcyca say we should avoid w/ a holter monitor and what type of clothes are appropriate?   1) magnetic fields. 2) Loose clothing  
🗑
Pre-op care for Holter Monitor:   tell pt. to wear loose clothing, 2) sponge bath only 3) avoid magnets andmetal detectors, 4) monitore placement of electrodes 5) diary 6)push event button when symptomatic  
🗑
post care for Holter:   return at scheduled time..ECG recording will be retrieved for inspection  
🗑
rhythms are saved on a memory loop and is used for monitoring the heart for a longer period than ECG and Holter monitor is called:   Implantable loop recorder (ILR)  
🗑
ILR monitors are useful to monitor pts especially during what episodes   syncopal episodes  
🗑
The device (ILR) is implanted where in the skin in what part of the body?   just under the skin, in the chest area.

🗑
Pre op for echo   none; just tell pt. it is painless  
🗑
post op for echo   remove gel from skin; no special care needed  
🗑
what is used when echocardiogram is not diagnostic?   transesophageal echocardiogram (TEE)  
🗑
probe of TEE is insterted through esophagus down to what organ? and behind or infront of the heart?   stomach, behind heart  
🗑

🗑
MUGA: what medication may be administered and how?   nitro; sublingually to assess for ventricular function  
🗑
pre op for MUGA:   tell what to expect: radioactive; can be done at rest or exercise; NPO 2hrs B4 test; IV infusion; SIGNED consent

What did Mrs. Gorcyca say about which test always goes with stress test?   ECG: continuous  
🗑
When is the stress test stopped?   1) symptoms of CAD; 2) pt stops for whatever reason; 3) maximum heart rate achieved (220 - pts age = maximum heart rate); 4) significant changes found in ECG

Stress test: what should you monitor aside from the ECG strip   BP  
🗑
Nurse was told that two pts that went through a stress test had false negative and false positive results. The nurse interprets this as:   common: test is not flawless  
🗑
T or F: Because stress tests has flaws it is not the best noninvasive test for CAD.   False, it remains the best noninvasive test. Invasive test would be cardiac cath  
🗑
T or F: stress tests can cause symptoms of CAD   true: increased exercise can deplete oxygen to the myocardium

a type of perfusion scanning using thallium is called   Thallium imaging  
🗑
uses of thallium imaging   1) assess myocardial blood flow; 2) detect old and new myocardial ischemia 3) evaluate coronary artery bypass grafts  
🗑
T or F: Thallium imaging only detects new myocardial ischemia   false: detects old and new  
🗑
What did Mrs. Gorcyca mean when she said you see cold spots during a thallium imaging test   thallium doesn't enter infarcted (necrotic) or scarred areas and will show as a cold spot (imaging will show that thallium stopped at that area)  
🗑
T or F: Scar-induced ischemia resolves with rest   False: Exercise ischemia resolves w/ rest, scar does not  
🗑
scar induced ischemia can be caused by what disorder   AMI  
🗑
if a patient is not able to exercise during a thallium imaging test, what is done?   Persantine/dpyridamole is given to mimic effect of exercise.  
🗑
how does persantine work   mimics exercise by increasing vasodilation of coronary arteries ->increases blood flow to well perfused areas-> then steals blood from ischemic areas = differences in flow will show up in scan  
🗑
T or F: Thallium imaging can be done only at rest and during exercise   False: can be done at rest (probably due to diprydamole/persantine) and after exercise  
🗑
thallium imaging pre-op:   1) Tell pt. radiation is given via IV and is a small dose and eliminated quickly.2) Same as stress test: NPO 2hrs before, no caffeine. BP monitoring, loose clothing and comfortable shoes. Beta blocker if prescribed. SIGNED CONSENT
