Anatomy
This layer of the heart wall is composed primarily of cardiac muscle.
What is the myocardium?
This common condition is also known as high blood pressure.
What is hypertension?
The “lub” sound in the heartbeat is caused by the closing of these valves.
What are the AV (atrioventricular) valves?
This node is the heart’s natural pacemaker.
What is the SA node?
This vascular condition involves fatty deposits in arterial walls.
What is atherosclerosis?
These two upper chambers receive blood returning to the heart.
What are the atria?
This condition occurs when blood flow to part of the heart is blocked, often by a clot.
What is a myocardial infarction?
The “dub” sound is associated with the closure of these valves.
What are the semilunar valves?
The phase of the cardiac cycle when the heart muscle contracts.
What is systole?
A sudden blockage of a blood vessel in the lungs by a clot is called this.
What is a pulmonary embolism?
This valve prevents backflow from the left ventricle into the left atrium.
What is the mitral valve?
In this condition, the heart can't pump blood efficiently to meet the body's needs.
What is congestive heart failure?
An extra heart sound, often described as a "gallop," is commonly found in heart failure.
What is S3?
The volume of blood the heart pumps per minute is called this.
What is cardiac output?
This condition involves the formation of a clot in a deep vein, usually in the legs.
What is deep vein thrombosis?
This muscular wall separates the left and right sides of the heart.
What is the septum?
This inflammatory disease can develop after untreated strep throat and affect the heart valves.
What is rheumatic heart disease?
A murmur is caused by this type of blood flow through the heart.
What is turbulent flow?
This electrical event corresponds to atrial depolarization on an ECG.
What is the P wave?
An abnormal ballooning of a blood vessel wall is called this.
What is an aneurysm?
The heart is located in this cavity of the thorax.
What is the mediastinum?
This congenital condition involves a hole between the heart's chambers.
What is a septal defect?
This systolic murmur is often heard in aortic stenosis.
What is a crescendo-decrescendo murmur?
This law states that stroke volume increases in response to an increase in the volume of blood filling the heart.
What is the Frank-Starling law?
This autoimmune condition causes inflammation of blood vessels.
What is vasculitis?
