Define It
Uncoordinated muscle activity in the heart, which results in a "quivering" rather than pumping action
What is Fibrillation
The closed cavity between the lungs holds the heart, major vessels, trachea, and esophagus
What is the Mediastinum
This chamber of the heart sends to blood through the tricuspid valve into the right ventricle
What is the Right Atrium
This device graphs the electrical activity of the heart
What is an Electrocardiogram
The heart is divided into this many chambers
What is Four (4)
An inadequate blood supply to a localized area caused by a blockage of vessels
What is Ischemia
This is a slippery double-layered membrane that encloses the heart
What is the pericardium
These are the two phases of the cardiac cycle
What is systole and diastole
These are the physical events that create the 'Lub-Dub' sound of a heart beat
What is closing of the heart valves
This is the most commonly used incision during open cardiac surgery
What is Median
This is when the heart muscle contracts to pump blood into the aorta
What is Systole
These are the three layers that make up the heart wall
What is the epicardium, myocardium, and endocardium
This is known as the pacemaker of the heart
What is the SinoAtrial (SA) Node
During this interventional radiology procedure, the doctor inserts a wire into the heart chambers and vessels via a peripheral artery or vein.
What is a Cardiac Catheterization
This artery supplying the heart muscle is the most likely to become blocked
What is the Left-Anterior-Decending (LAD) Artery
Intentional stoppage of all cardiac activity during cardiac surgery
What is Cardioplegia
This is the side of the heart containing the Bicuspid (or Mitral) Valve
What is the Left Side
This chamber of the heart typically has the strongest muscle
What is the Left Ventricle
With a normal reading above 90%, this can be measured during cardiac catheterization or with a Pulse Ox.
What is Oxygen Saturation
These vessels carry blood from the tricuspid valve to the lungs
What are the Pulmonary Arteries
A congenital narrowing or stricture in the aorta
What is Coarctation
This cavity is enclosed by the rib cage and contains the heart and lungs
What is the Thoracic Cavity
This region of the heart keeps the electrical impulse from reaching the ventricles until after the atria are done contracting
What is the AtrioVentricular (AV) Node
Normally between 50% and 70%, this percentage of the left ventricle's total-blood-volume is pumped into the aorta every beat
What is Ejection Fraction
This is what the heart muscle will do if the nerves between the brain and heart are completely severed
What is continue to pump/beat
