EKG Crossword

1. 1) the part of the heart from which depolarization originates 2) a small device that's implanted in the chest to help control the heartbeat
6. the absence of symptoms
8. AFib increases the risk of this by 4 to 6 times
11. a secondary, smaller electrical shift that takes place after a depolarization, preparing the cells for depolarization
14. Electrical or magnetic interference that alters the EKG tracing
16. shortness of breath
17. a state of cardiac standstill with no cardiac output and no ventricular depolarization; also known as "flatline"
18. a rate of less than 60 bpm in adult patients, and 80 in pediatric patients
19. the removal, isolation or destruction of cardiac tissue or conduction pathways; procedure to treat AFib

9. type of heart monitor that records the heart’s activity for 24-96 (or more) hours
10. characterized by a sawtooth P wave configuration
12. EKG graph line when there is no electrical activity taking place; also called the isoelectric line
13. rhythm that is typically regular with narrow QRS and absent or inverted P waves
15. high blood pressure
16. wave often seen in WPW
