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

airflow is followed by a minimum of how many seconds of EEG
frequency change - ✔✔✔ Correct Answer > 3 seconds

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
