detailed answers ||\\//||
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
