BSMH Advanced Arrhythmia Course Exam Questions
and Answers
Blood flow through the heart - -SVC --> Rt atria --> Tricuspid --> Rt ventricle --> Pulmonic
valve --> Lungs --> Lt atria --> Mitral valve --> Lt ventricle --> aortic valve --> aorta --> Body
-EKG Times - -6 second strip
1 small block = 0.04 secs
1 big block = 5 small boxes = 0.20 secs
15 big blocks = 3 seconds
-P Wave - -atrial depolarization
-PR Interval - -time it takes for the impulse to get from atrial to ventricles
0.12 - 0.20 seconds
-QRS Interval - -ventricular depolarization
< 0.12 seconds
-ST Segment - -early depolarization of ventricles
depression = myocardial infarction
elevation = myocardial injury
-T Wave - -repolarization of ventricles
-Heart blocks - -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
-Conduction pathway - -Sinus node - inerarterial tracts - atrium - intermodal tracts - AV
node - bundle of HIS - bundle branches - purkinje fibers - ventricles
-Inherent rates - -SA node = 60-100
AV node = 40-60
Ventricle = 20-40
-Atrial flutter - -Sawtooth pattern
-Atrial fibrillation - -Waves between QRS
-Supraventricular tachycardia - -No P wave, rate > 150
