Deoxygenated blood from the lower part of the body (below the diaphragm) enters the heart via which blood vessel?
Inferior vena cava
The ___________________ receives the electrical signal from AV node.

Patient has hypokalemia
When deoxygenated blood travels from the Right atrium to the Right ventricle it gets pushed through which valve?
The _________receives electrical signals from the SA node
AV node
What is an electrode?
Sticky pads with conductive gel used to connect lead wires
V5 is placed on?
