Blood flow through the heart - VERIFIED ANSWER - SVC --> Rt atria -->
Tricuspid --> Rt ventricle --> Pulmonic valve --> Lungs --> Lt atria -->
Mitral valve --> Lt ventricle --> aortic valve --> aorta --> Body
EKG Times - VERIFIED 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 - VERIFIED ANSWER - atrial depolarization
PR Interval - VERIFIED ANSWER - time it takes for the impulse to get
from atrial to ventricles
0.12 - 0.20 seconds
QRS Interval - VERIFIED ANSWER - ventricular depolarization
< 0.12 seconds
,ST Segment - VERIFIED ANSWER - early depolarization of ventricles
depression = myocardial infarction
elevation = myocardial injury
T Wave - VERIFIED ANSWER - repolarization of ventricles
Heart blocks - VERIFIED 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
Conduction pathway - VERIFIED ANSWER - Sinus node - inerarterial
tracts - atrium - intermodal tracts - AV node - bundle of HIS - bundle
branches - purkinje fibers - ventricles
Inherent rates - VERIFIED ANSWER - SA node = 60-100
AV node = 40-60
Ventricle = 20-40
, Atrial flutter - VERIFIED ANSWER - Sawtooth pattern
Atrial fibrillation - VERIFIED ANSWER - Waves between QRS
Supraventricular tachycardia - VERIFIED ANSWER - No P wave, rate >
150
Junctional rhythms - VERIFIED ANSWER - P wave inverted or absent
Junctional bradycardia: < 40
Junctional rhythm: 40-60
Accelerated junctional: 60-100
Junctional tachycardia: > 100
Ventricular tachycardia - VERIFIED ANSWER - marching nuns
Torsades de pointes - VERIFIED ANSWER - Rate > 200, no P waves, wide
QRS
Ventricular fibrillation - VERIFIED ANSWER - Rate cannot be counted
