BSMH Advanced Arrhythmia Course
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
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
P Wave ------- ✔ CORRECT ANSWER ✓✓atrial depolarization
PR Interval ------- ✔ CORRECT ANSWER ✓✓time it takes for the impulse to get from atrial to
ventricles
0.12 - 0.20 seconds
QRS Interval ------- ✔ CORRECT ANSWER ✓✓ventricular depolarization
< 0.12 seconds
ST Segment ------- ✔ CORRECT ANSWER ✓✓early depolarization of ventricles
depression = myocardial infarction
elevation = myocardial injury
T Wave ------- ✔ CORRECT ANSWER ✓✓repolarization of ventricles
