Using these questions as guides analyze each of the followin

Using these questions as guides, analyze each of the following abnormal three-beat EKG tracings. Are all named wave forms present for each heart beat? What is wave form is missing? Which part of the heart is represented by this missing wave form? Give 2 hypotheses Are all wave forms present for each heart beat? What is missing? Which part of the heart is represented by this missing wave form? Are all wave forms present for each heart beat ? What is missing? Is the atrial heart rate normal? Is the ventricular HR normal? Which node is note working correctly?

Solution

1. a.Yes all 3 are present.

b.1st small wave is P, long wave is QRS complex, next to QRS is T wave.

c.. S wave missing - this represents ventricular recovery.

2.

a. No.

b. P wave is missing . because no initial wave.

c. P wave is generated by activation of arteria.

3. a. No.

b. P wave missing

c. ventricular heart rate is not normal. QRS complex should be 120ms. But here it is much shorter.

d. SA node not working properly so P wave missing
