Electrocardiography and blood pressure

Question 1

ECG

Answer 1

recording of the electrical activity of the heart

Question 2

systole

Answer 2

the part of the cardiac cycle when the ventricles contract

Question 3

diastole

Answer 3

the part of the cardiac cycle when the heart refills with blood following systole

Question 4

diastolic pressure

Answer 4

the lowest pressure between heart beats when the heart relaxes

Question 5

systolic pressure

Answer 5

the highest arterial blood pressure that is reached when the ventricles contract

Question 6

pulse pressure

Answer 6

the difference between systolic and diastolic pressure readings, mmHg

Question 7

arterial mean pressure

Answer 7

the average arterial pressure during a single cardiac cycle

Question 8

respiratory sinus arrhythmia

Answer 8

how respiration can effect heart rate, during inhalation heart rate will increase, during exhalation heart rate will decrease

Question 9

peripheral resistence

Answer 9

the resistance in arteries to blood flow

Question 10

baroreceptor reflex

Answer 10

reflex mechanism starting from baroceptors in the carotid sinus and aortic arch that regulates blood pressure

Question 11

bainbridge reflex

Answer 11

an increase in heart rate due to an increase in central venous pressure
