4 Cards in this Set

  • Front
  • Back
  • 3rd side (hint)
What type of heart block does this image depict?
SA block (the missing P wave suggests that the atrial impulse is absent, thus the ventricles set the pace.)
Which wave is missing?
What type of heart block does this image suggest?
First degree AV heart block (The prolonged PR interval is >0.20 seconds)
PR interval is 0.20 sec > t < 0.35 sec
2nd degree A-V heart block (lead V3)
This image shows a dropped beat. What type of block does this suggest? (Sometimes this type of block has a atrial:ventricular ratio of 2:1, 3:2 or 3:1)
What type of heart A-V heart block is depicted here?

What has happened to the ventricles?
a) Complete A-V heart block (lead II)


b) ventricular escape (Both the ventricles and the atria are beating at different rates... Because the ventricles were not receiving an impulse the defaulted to their intrinsic rate.)
What would cause the P wave and the QRS wave to be
