The beginning of one heartbeat to the beginning of the next is called?

• Electrocardiogram

• Systole

• Cardiac Cycle

• Diastole

What is the formula for Cardiac output?

• stroke volume x heart rate

• heart rate x end-diastolic volume

• stroke volume x end-systolic volume

• end-systolic volume - end-diastolic volume

Which area of the conduction system is known as the pacemaker of the heart?

• AV Node

• SA Node

• Purkinje fibers

• Bundle of His

What area of the heart is responsible for the delay of conduction between the artrium and ventricles?

• AV node

• Bundle of His

• Right bundle branch

• Left bundle branch

The normal pattern of impulse conduction through the heart is:

• AV-SA-AVB (Bundle of His)-Purkinje

• AV-SA-Purkinje-AVB (Bundle of His)

• SA-AV-AVB (Bundle of His)-Purkinje

• SA-AV-Purkinje-AVB (Bundle of His)
