Practically speaking there are 2 dimensions in which electrodes can be placed... This record is called a ____ ___ ____ ____.

• A. Conventional 12 Lead EKG
• B. Modified Chest Left
• C. Standard Limb Leads
• D. Precordial Leads

Answer: (A)

The main idea is that a heart’s electrical activity is captured from multiple viewpoints by placing electrodes in two planes: limb leads give a view in the frontal plane, and precordial (chest) leads give a view in the horizontal plane. When these views are combined into 12 distinct leads, you get the conventional 12-lead EKG. That’s why the phrase completes as “Conventional 12 Lead EKG.” The other options refer to parts of the setup or to a nonstandard configuration, but they don’t describe the full two-dimensional recording that yields 12 leads.
