Across
  1. 4. electrical activity of the heart initiated by the sinoatrial node
  2. 6. the part of an ECG that reflects conduction of an electrical impulse from the sinoatrial node through the atrioventricular node
  3. 7. electrical current given in synchrony with the patient’s own QRS complex to stop an arrhythmia
  4. 9. purposeful destruction of heart muscle cells, usually in an attempt to correct or eliminate an arrhythmia
  5. 12. ability of the cardiac cells to initiate an electrical impulse
  6. 14. the part of an ECG that reflects repolarization of the ventricles
  7. 16. rate of impulse formation
  8. 18. the part of an ECG that reflects the time from ventricular depolarization through repolarization
  9. 20. distorted, irrelevant, and extraneous electrocardiographic (ECG) waveforms
  10. 22. arrhythmia that has a sudden onset and terminates spontaneously; usually of short duration, but may recur
  11. 23. a record of a test that graphically measures the electrical activity of the heart, including each phase of the cardiac cycle
  12. 24. the part of an ECG that may reflect Purkinje fiber repolarization; usually, it is not seen unless a patient’s serum potassium level is low
Down
  1. 1. the part of an ECG that reflects the end of the QRS complex to the beginning of the T wave
  2. 2. the duration between the beginning of one QRS complex and the beginning of the next QRS complex; used to calculate ventricular rate and rhythm
  3. 3. process by which cardiac muscle cells change from a more negatively charged to a more positively charged intracellular state
  4. 5. electrical current given to stop an arrhythmia, not synchronized with the patient’s QRS complex
  5. 6. the duration between the beginning of one P wave and the beginning of the next P wave; used to calculate atrial rate and rhythm
  6. 8. conduction velocity
  7. 10. the part of an ECG that reflects conduction of an electrical impulse through the atrium; atrial depolarization
  8. 11. the part of an ECG that reflects conduction of an electrical impulse through the ventricles; ventricular depolarization
  9. 13. transmission of electrical impulses from one cell to another
  10. 15. disorder of the formation or conduction (or both) of the electrical impulse within the heart, altering the heart rate, heart rhythm, or both and potentially causing altered blood flow (also referred to as dysrhythmia)
  11. 17. force of myocardial contraction
  12. 19. process by which cardiac muscle cells return to a more negatively charged intracellular condition, their resting state
  13. 21. the part of an ECG that reflects the time between the end of the T wave and the beginning of the next P wave; used to identify the isoelectric line
