Parts of the Heart
The area of where the heart located?
What is the left side of the thoracic cavity?
Refers to when the electrical impulse starts in the SA node and causes the atria to contract.
Responses
What is atrial depolarization?
A reduction in blood flow to the heart.
What is myocardial ischemia?
The average time a cardiac cycle last?
What is 0.8 seconds?
The wave of the EKG cycle shows repolarization?
What is the T wave?
The chamber of the heart that receives deoxygenated blood from the body.
Responses
What is the right atrium?
What an electrocardiogram measures.
What is heart function?
The stiffening of blood vessels due to fatty plaque buildup.
Responses
What is atherosclerosis?
The name of the tissue known as the body's "natural pacemaker?"
Responses
What is the SA node?
The component of the EKG cycle that shows ventricular depolarization?
Responses
What is the QRS component?
The chamber of the heart that contracts to send blood to the pulmonary artery and lungs?
Responses
What is the right ventricle?
This network of fibers spreads the impulse to the ventricles, causing them to contract.
What is the Purkinje fibers?
When cardiac arrest occurs.
What is when the heart stops beating unexpectedly.
The contraction phase of a heartbeat.
What is systole?
Wave of the ECG cycle shows atrial depolarization.
What is the P wave?
Number of chambers that the heart has.
Responses
What is 4 chambers?
Time of electrical recovery in the ventricles before the cycle starts again
What is repolarization?
The most common symptom of cardiac compromise.
What is angina?
Oxygen poor blood.
What is deoxygenated blood?
Passes impulse from the AV node to the Purkinje fibers.
What is the bundle of His?
Part of the heart that keeps blood flowing in one direction.
What is the valves of the heart?
When the impulse starts in the SA node and causes the atria to contract.
What is atrial depolarization?
When blood flow to the heart is blocked?
What is a heart attack?
Flow of blood between the heart and the cells of the body.
What is systemic circulation?
The relaxation part of a heartbeat.
What is diastole?
