Using the Book of Style, write out the correct format for the various leads used in an EKG:

What will be an ideal response?

Question 2

Compare the terms concentric and eccentric. Why do you think eccentric plaque causes turbulence?

What will be an ideal response?

Answer to Question 1

Standard bipolar leads: lead I, lead II, lead III
Augmented limb leads: aVR, aVL, aVF
Precordial leads: V1, V2, V3, etc, or V1, V2, V3, etc.

Answer to Question 2

Concentric refers to circles within circles, or in the case of plaque, circular layers that build upon each other, eventually narrowing the diameter of the vessel lumen. Eccentric describes a less predictable pattern of accumulation. Blood flowing through concentric plaque still moves more or less in a straight line. Blood moving through an artery with eccentric plaque does not move in a straight line. Pockets formed by irregularly shaped outcroppings of plaque cause the blood to change directions, resulting in swirls and turbulence.
