Across
- 4. to pace Pacemaker malfunction in which no pacing spike occurs when expected
- 7. pacing Pacing delivered through a lead inserted through a vein into the heart
- 9. pacing Pacing with a spike occurring before the QRS complex
- 10. Pacemaker incorrectly detects electrical activity and withholds pacing
- 14. to capture Pacemaker malfunction in which a pacing spike occurs but no cardiac response follows
- 17. pacing Pacing delivered through electrodes placed on the skin
- 19. pacing Pacing using leads attached directly to the heart's outer surface
Down
- 1. generator Device that produces the electrical pacing impulse
- 2. interference Electrical activity that can interfere with pacemaker function
- 3. pacemaker A device used temporarily to initiate cardiac electrical activity
- 5. Minimum electrical energy needed to consistently depolarize the heart
- 6. rate Number of impulses delivered by the pacemaker per minute
- 8. Pacemaker's ability to detect intrinsic cardiac activity measured in mV
- 11. Component that contacts cardiac tissue and delivers the pacing impulse
- 12. chamber pacing Pacing that stimulates both the atria and ventricles
- 13. lead Wire that carries electrical impulses to the heart
- 15. Pacemaker fails to recognize the patient's intrinsic cardiac activity
- 16. Strength of the pacemaker electrical impulse measured in mA
- 18. pacing Pacing with a spike occurring before the P wave
