Across
  1. 3. When the heart beats regularly but faster than it should; occurs in the upper chambers of the heart\
  2. 6. Time from the beginning of the ventricular depolarization to the end of the ventricular repolarization
  3. 7. Time from the beginning of atrial depolarization to the beginning of ventricular depolarization
  4. 9. Instrument used to measure changes in the heart
  5. 11. Occurs in the lower chambers of the heart; the lower chambers contract in a very rapid and uncoordinated manner
Down
  1. 1. Recording of the changes in the membrane potential
  2. 2. Slow heart rate; below 60 impulses per minute
  3. 4. Irregular heart rhythm that occurs in the upper chambers of the heart
  4. 5. Repolarization of the ventricles
  5. 6. Depolarization of both ventricles and contraction of the ventricular muscle
  6. 8. Faster heart heart; over 100 impulses per minute
  7. 10. Atrial depolarization
