What type of lead placement is most often used to record ECG
in sleep studies - ✔✔✔ Correct Answer > Single Modified EKG
Lead II using torso electrode placement is RECOMMENDED
Hypoxiema and hypokalemia are often causes of what cardiac
arrhythmia - ✔✔✔ Correct Answer > PVC
What is another name for asystole and how many leads are
required to confirm this arrhythmia - ✔✔✔ Correct Answer >
"Ventricular Standstill"
ALWAYS 2 LEADS
Which heart block, defined as a PR interval greater than
0.20sec, may be caused ischemia and digitalis - ✔✔✔ Correct
Answer > 1st Degree AV block
,("If the R is far from the P then you have a 1st degree)
Which heart block presents as an increasing longer and longer
PR interval with a dropped QRS - ✔✔✔ Correct Answer > 2nd
degree AV block Mobitz I (WENCHEBACH)
"Longer longer longer drop then you got a Wenchabach"
If some the P's don't get through (no QRS), with NO enlogating
PR interval - ✔✔✔ Correct Answer > 2nd degee av block
(MOBITZ II)
P wave (SA signal) does not get through to (AV node) and
therefore no ventricular contraction (i.e. NO QRS)
"If some of the P's don't get through then you have a MOBITZ
TYPE II"
"If the P's and the Q's don't agree then you have a _____
degree" - ✔✔✔ Correct Answer > 3rd degree av block
seperate (different) atrial and ventricluar rates.
Atrial rate usually higher than Ventricular rate
___________ is indicated by depressed or inverted T wave.
,Another cause of inverted T wave is the result of certain levels
of what electrolyte - ✔✔✔ Correct Answer > Ischemia
Hypokalemia
Myocradial Injury is indicated by what ECG finding - ✔✔✔
Correct Answer > Elevated ST segment
Myocardial Infraction is indicated by what ECG finding - ✔✔✔
Correct Answer > Significant Q waves that are 1/2 the size of
the R wave
What ECG finding is associated with HYPERkalemia - ✔✔✔
Correct Answer > Elevated or spiked Twaves
If only one P wave is different from all other Pwaves and the
rest of the ECG is normal, what could this be - ✔✔✔ Correct
Answer > PAC (Premature Atrial Contration)
Atrial ectopic focus fires before the SA node
A prescription has been recieved by a home therapy DME
provider following completion of a CPAP titration study. The
next step to verify that the pt was set up at home is to:
, a. have the selected provider confirm pt set up
b. call ins company and request copy of provider bill
c. check with the pt to confirm provider set up
d. contact the physician to confirm set up - ✔✔✔ Correct
Answer > a.
Which of the following should the sleep tech document at
regular intervals during each sleep study?
a. ambient noise level
b. impedance checks
c. room temperature
d. body position - ✔✔✔ Correct Answer > d.
A apnea related arousal is scored when a 10 cessation of
airflow is followed by a minimum of how many seconds of EEG
frequency change - ✔✔✔ Correct Answer > 3 seconds
What two other criteria are required to score a hypopnea with
3% SpO2 desaturation - ✔✔✔ Correct Answer > 1. At least 50%
reduction in airflow (nasal) from baseline for at least 90% of the
events duration.
2. Event lasts at least 10 seconds
