(infrared signal is bounced off the eardrum and provdes accurate reading in 2 secinds)

popular with younger children bc of rapid measurement

Answer 9

tymphanic reading

Answer 10

temporal scanner

Question 11

is the rhythmic expansion of an artery each time the heart beats.

Answer 11

pulse

Question 12

artery throughout the body has a pulse, although many pulses cannot be read because of their location.

Answer 30

The electrocardiogram (ECG; sometimes called EKG)

Question 31

occurs when the rate or rhythm of the heartbeat is altered.

Answer 31

sinus arrythmia

Question 32

Answer 32

atrial arrythmia

Question 33
