test that..

• records the electrical activity of the heart

• records the electrical currents associated with the heart muscle activity

specific sounds heard in the stethoscope when taking a BP

Metabolism

the process by which your body converts what you eat and drink into energy

Palpate

examining or exploring through touching

Pulse

rhythmic beating of the arteries produced by regular contractions of the heart
