BSMH Advanced Arrhythmia Course
Questions and Answers
Question 1
Blood flow through the heart
Correct Answer
SVC --> Rt atria --> Tricuspid --> Rt ventricle --> Pulmonic valve --> Lungs --> Lt
atria --> Mitral valve --> Lt ventricle --> aortic valve --> aorta --> Body



Question 2
EKG Times
Correct Answer
6 second strip
1 small block = 0.04 secs
1 big block = 5 small boxes = 0.20 secs
15 big blocks = 3 seconds



Question 3
P Wave
Correct Answer
atrial depolarization



Question 4

, Question 5
QRS Interval
Correct Answer
ventricular depolarization
< 0.12 seconds



Question 6
ST Segment
Correct Answer
early depolarization of ventricles
depression = myocardial infarction
elevation = myocardial injury



Question 7
T Wave
Correct Answer
repolarization of ventricles



Question 8
Heart blocks
Correct Answer
No changes in PR Interval
- QRS complexes present = 1st degree
- No QRS complexes = 2nd degree type II

Changes in PR Interval
- R to R interval regular = 3rd degree
- R to R interval irregular = 2nd degree type I
