Advanced Arrhythmia Exam Prep
1. what does each small box represent: .Ans- 04 seconds
2. what does 1 large box (5 small boxes) represent: . Ans- 20 seconds
3. what do 5 large boxes represent: Ans- 1 second
4. primary pacemaker: Ans- SA node w/expected firing rat of 60-100 bpm
5. backup pacemaker: Ans- AV node w/expected firing rate of 40-60 bpm
6. final pacemaker: Ans- ventricles w/expected firing rate less than 40
bpm
7. a normal PR interval is: . Ans- 12-.20 seconds
8. a normal QRS interval is: < . Ans- 12 seconds (.04-.11)
9. a normal QT interval is: . Ans- 36-.44 seconds
10.the ST segment should be with the : Ans- level w/ the
baseline
11.ST segment elevation and depression is an indication of: Ans- ischemia
or injury to the heart
12.what does P wave represent on the ECG: Ans- atrial depolarization
13.what does P wave represent on the ECG: Ans- ventricular depolarization
14.what does P wave represent on the ECG: repolarization of ventricles
15.rhythms that originate above the ventricles normally have a
QRS complex: Ans- narrow QRS complex
1/
, 16. rhythms that
originate in the ventricles normally have a QRS complex-
: Ans- wide QRS complex
17.A Flutter: rate: 250 - 350 bpm HR
varies!! regularity: regular or irregular
P waves: "think of a shark fin or
waves" PR: not applicable - you
don't measure it QRS: < .12 secs
18.A Fib: rate: fast &
unmeasurable regularity:
irregular
P wave: NON. wavy baseline btwn QRS
instead PR: not applicable - you don't
measure it
QRS: <.12 secs
19.(1*AVB): NO DROPPED
QRS PR interval > .20 secs
E
20.(2*AVB): PR wave gets longer + longer UNTIL QRS is DROPP
D
21.2*AVB type 2: PR intervals remain constant, but some QRSROPPED
is D
22. 3*AVB: rate: 60 - 100
HR PR intervals vary
R-R constant, P-P constant
some QRS complexes are DROPPED
