Across
  1. 1. the cardiomyocyte that generates a signal to contract
  2. 4. heart rate is more than 100 bpm (fast HR)
  3. 5. the cardiomyocyte that conducts signal to contract
  4. 8. cells contract very rapidly but in a "coordinated" way, like the fluttering of a butterfly's wings
  5. 9. the "phase" where there is a slow Ca2+ current preventing summation from happening
  6. 12. the backup pacemaker node (2ed pacemaker)
  7. 15. the lead that provides a "frontal" view of the heart
  8. 16. the main pacemaker node
  9. 18. isoelectric baseline between waves
  10. 19. the cell contracts very rapidly but in an "uncoordinated" way
Down
  1. 2. the cardiomyocyte that contracts
  2. 3. heart attack
  3. 6. segment plus wave
  4. 7. a record of the heart’s electrical activity as it travels through the conduction system with every heartbeat
  5. 10. heart rate is less than 60 bpm (slow HR)
  6. 11. another name for the Na+/T-type Ca2+ current when its channels open when cells repolarize
  7. 13. irregular heart rhythms
  8. 14. the lead that provides a "transverse" view of the heart
  9. 17. a strong electrical shock to the chest
