Cardiac Functions
This is the total volume of blood pumped per minute
What is Cardiac Output?
This is the force that drives blood flow
What is change in pressure?
This heart rate zone is represented by 70-80% of heart rate max
What is zone 3?
Electrical signals spread via this structure
What are gap junctions?
When cardiac cells are resting, they have this charge
What is a negative charge?
SV/EDV is used to determine this cardiac function
What is Ejection Fraction?
This is the force that opposes blood flow
What is Resistance?
This zone builds capillary density
What is zone 2?
When this node delays, it relays signals to the ventricles
What is the AV node?
This type of training improves endothelial function
What is aerobic training?
This equation is used to determine the volume of blood pumped in one heartbeat
What is SV = EDV-ESV?
These vessels are responsible for the majority of gas and nutrient exchange
What are capillaries?
Training at this intensity improves recovery
What is zone 1?
This node initiates contraction signal
What is the SA node?
This chamber of the heart has the most myocardium
What is the Left Ventricle?
During this phase of the cardiac cycle the chambers of the heart fill with blood
What is Diastole?
This equation is used to find blood flow
What is ▵P/R?
In this zone, lactate and metabolic waste products will build in your system quickly
What is zone 5?
This is the recording of a heart's electrical activity
What is a ECG?
This type of training can increase mitochondria density by 40%
What is aerobic training?
This is the cardiac output of an individual with a heart rate of 70 bpm, a stroke volume of 70 mL/beat and an EDV of 100 mL
What is 4,900 mL/min?
These vessels are responsible for 70-80% of pressure drop in blood flow
What are arterioles?
This zone improves efficiency of blood circulation in the heart
During this phase of a ECG, atrial polarization and ventricular depolarization is occurring
What is the QRS complex?
These structures are sensitive to changes in arterial pressure
What are Baroreceptors?
