BSMH ADVANCED ARRHYTHMIA ACTUAL
TEST PAPER WITH VERIFIED ANSWERS
●● QRS length
Answer: 0.6- 0.12 seconds
●● QT length
Answer: 0.36-0.44
●● dangerous QT length
Answer: > 0.50 seconds
●● small box time
Answer: 0.04 seconds
●● large box time
Answer: 0.20 seconds
●● SA node rate
Answer: 60-100
●● AV node rate
,Answer: 60-40
●● purkinje fibers rate
Answer: 20-40
●● six second strip method
Answer: -least accurate
-count number of QRS complexes on six-second strip and multiply by
10
-provides a mean heart rate
●● small squares method
Answer: - count the number of small squares between 2 complexes
- divide into 1500
-ONLY FOR REGULAR RHYTHMS
ex. 24 small squares between
1500/24 = 62 BPM
●● NSR
Answer: rate = 60-100
PRI = 0.12-0.20
, constant P waves
QRS = 0.06-0.10 (>0.12 if BBB)
●● bundle branch block
Answer: interruption in flow of electrical impulses resulting in wide (>
0.12), notched QRS
part of underlying rhythm
●● bundle branch block intervention
Answer: -continue to monitor
-notify provider if new finding
●● sinus bradycardia
Answer: NSR with rate < 60
●● sinus bradycardia interventions
Answer: 1. check pt for symptoms
2. if symptomatic RRT, IV atropine, or pacing
●● sinus tachycardia
Answer: NSR with rate > 100
