which word parts do you need to build a medical word that means procedure to puncture (the membrane) around the heart?

o - tomy, endo-, cardi/o-

o - centesis, peri-, cardi/o-

o - ator, de-, fibrill/o-

o - plasty, atri/o-, cardi/o-

Explanation:

An electrocardiogram (ECG or EKG) is a record of the electrical activity of the heart. The suffix "-centesis" means puncture (to withdraw fluid), "peri-" means around, and "cardi/o" means heart. So, "pericardiocentesis" is the procedure to puncture (the membrane) around the heart.

Answer:

For the first question: a record or picture of the electricity of the heart.
For the second question: -centesis, peri-, cardi/o-.
