How many leads are placed on the frontal plane in the conventional 12 lead EKG?

Explanation:
Leads that view the heart in the frontal plane are the six limb leads. In the standard 12-lead ECG, these are I, II, III, aVR, aVL, and aVF, formed by the limb electrode placements and their combinations. The other six leads (V1–V6) are chest leads mapped to the horizontal plane. So the number placed on the frontal plane is six.
