Advanced 12 Lead EKG Lecture Worksheet #6
True or False
____1. In a patient experiencing an acute coronary syndrome, ST segment elevation in the
shape of a “smiley” face (upward concavity) is usually associated with an acute injury
pattern.
____2. Placement of right Precordial leads is identical to the standard Precordial leads except
on the right side of the chest.
____3. 0.12 seconds is equal to 120 milliseconds
____4. The axes of leads I, II, and III form an equilateral triangle with the heart at the center.
(Einthoven’s triangle). If the augmented limb leads are added to this configuration and
the axes of the six leads moved in a way in which they bisect each other, the resulte is
the hexaxial reference system.
____5. The area supplied by an obstructed coronary artery goes through a characteristic
sequence of events that have been identified as zones of ischemia, injury and infarction.
Matching
____1. Lead located at the fourth intercostals space, left sterna border
____2. Common ECG finding in hyperkalemia
____3. The zone of _______ is typically characterized by ST segment elevation.
____4. Lead I + Lead III = __________.
____5. Occlusion of the left anterior descending coronary artery may result in a(n) _____ MI.
____6. Leads that view the heart in the horizontal plane.
____7. Leads that view the inferior wall of the heart.
____8. Lead I is perpendicular to lead ________.
____9. Occlusion of the right coronary artery may result in a(n) __________ MI.
____10. Leads used to view the right ventricle.
____11. Lead located at the fourth intercostals space, right sterna border
____12. Lead II is perpendicular to lead ________.
____13. Leads that view the heart in the frontal plane.
____14. Lead located at the fifth intercostals space, left midclavicular line.
____15. Direction of the mean QRS vector.
____16. Lead III is perpendicular to lead__________.
____17. Leads that view the lateral wall of the heart.
____18. The zone of ______is typically characterized by Q waves.
____19. Indicator of the magnitude and direction of current flow.
____20. Leads that view the septum.
