Cardiac Cycle

What is cardiac output?

• refers to the amount of blood the heart pumps in one minute

• refers to the amount of oxygen the heart pumps in one minute

• refers to the amount of waves the heart pumps in one minute

Calculation of cardiac output =

• heart rate x stroke height

• heart rate x stroke width

• heart rate x stroke volume

• heart rate x stroke

_____ is the numbers of time the heart beats in 1 minute

What is stroke volume?

• the number of times the heart beats in 1 minute

• the amount of blood ejected with each heartbeat

• the amount of blood pimped in 1 minute

Ways to affect cardiac output are

• heart rate change

• stroke volume change

• bradycardia

• tachycardia

What does the cardiac cycle consist of?

• atrial kick

• systole

• diastole

The series of events that occur from the beginning of one heartbeat to the beginning of the next is

• atrial systole

• isovolumetric relaxation

• cardiac arrest

• cardiac cycle

Contraction = ___ and Relaxation = ___

• systole/diastole

• diastole/systole

Do the atrias contract simultaneously?

• no

• yes

The first heart sound is

• s1

• s2

• louder

• longer
