Across
  1. 2. ventricular depolarization leading to the contraction of the ventricles, lasting 0.04-0.12 seconds
  2. 5. heart rate over 100 bpm, initially increases cardiac output, then decreases it over time
  3. 6. chaotic rhythm with no clear p wave, causing the atria to quiver
  4. 7. impulse from sa node, leading to atrial contraction
  5. 11. the point where the qrs complex transitions to the st segment
  6. 13. techniques such as carotid massage to slow down heart rate during supraventricular tachycardia
  7. 14. time between atrial depolarization and ventricular conduction, lasting 0.12-0.20 seconds
  8. 15. drug used to treat supraventricular tachycardia, helping to reset the rhythm
  9. 16. age, hypokalemia, hypomagnesemia, stress, nicotine, alcohol, and mi
  10. 20. 140-180 bpm due to repetitive firing of an irritable ventricular ectopic focus
  11. 21. rapid heart rhythms exceeding 100 bpm, increasing myocardial oxygen demand and reducing perfusion
  12. 23. duration from the beginning of the q wave to the end of the t wave
  13. 24. life-threatening rhythms like pvcs, v-tach, and v-fib
  14. 26. asynchronized countershock used to reset ventricular rhythms, primarily for v-fib and v-tach
  15. 27. slight variations in heart rate with breathing, such as increased rate during inspiration
  16. 28. heart rate less than 60 bpm due to excessive vagal stimulation
  17. 29. sharp, tearing, ripping pain in the chest or back
Down
  1. 1. life-threatening electrical chaos in ventricles, resulting in no cardiac output or pulse
  2. 3. increased irritability of ventricular cells, seen as early qrs complexes followed by a pause
  3. 4. synchronized countershock used to restore normal rhythm during an atrial dysrhythmia
  4. 8. rapid heart rate between 100-280 bpm with invisible p waves, often requiring adenosine or vagal maneuvers
  5. 9. the resting phase, begins at the j point and ends at the start of the t wave
  6. 10. full cardiac arrest with no electrical activity, requiring immediate cpr and epinephrine
  7. 12. two normal beats followed by one premature complex, followed by a pause, repeating the cycle
  8. 17. abnormal impulse generation, often with abnormal p waves, including pac, svt, and afib
  9. 18. fainting or sudden loss of consciousness, commonly seen in both tachycardia and bradycardia
  10. 19. premature atrial contractions, often caused by stress, caffeine, and alcohol
  11. 22. drug used to treat symptomatic bradycardia by increasing the heart rate
  12. 25. alternating normal and premature beats, followed by a pause, repeating the cycle
