Blood flow through the heart: - ANSWER Right atrium----tricuspid valve----
right ventricle---pulmonary artery---lungs----pulmonary vein---left atrium----
mitral (bicuspid valve)----left ventricle---aorta---arteries---arterioles----
capillaries---venuoles----veins, vena cava
Main components of CARDIAC CONDUCTION SYSTEM - ANSWER SA
node
AV node
bundle of His
bundle branches
Purkinje fibers
SA node (sinoatrial node) function? - ANSWER aka Anatomical Pacemaker -
Starts thesequence by causing atrial muscles to contract
Where does the SA node signal travel through? - ANSWER AV node ->
Bundle of His -> down bundle branches -> through Purkinje fibers (causes
Ventricles to contract)
Arteriosclerosis - ANSWER THICKening and LOSS of Elasticity of the
arterial walls
Atherosclerosis is a major cause of? - ANSWER CAD- coronary artery disease
When can Atherosclerosis appear? - ANSWER When the artery is about 75%
OCCLUDED.
Atheriosclerosis- MODIFIABLE causes - ANSWER - Cigarette/tobacco
smoking
, - HBP
- High blood cholesterol levels
Atherosclerosis- NON-Modifiable causes - ANSWER - Heredity
- Male sex
- Increased Age
Ways to treat CAD? - ANSWER Surgery
PTCA
CABG
Surgery for CAD is done why? - ANSWER If conservative medical
management fails
PTCA is? - ANSWER Percutaneous Transluminal Coronary Angioplasty
CABG is? - ANSWER Coronary Artery Bypass Graft
- A procedure to bypass a blocked section of a coronary artery and to deliver
oxygen to heart.
- Involves Coronary Stents
ACS is? - ANSWER Acute Coronary Syndrome
How does ACS begin? - ANSWER When a thrombus occludes a vessel.
During ACS, the SNS does what? - ANSWER In an attempt to support vital
functions, the Sympathetic Nervous System responds by increasing myocardial
demand such as INCREASED HR, BP, and AFTERLOAD
Symptoms of ACS? - ANSWER - Angina
- MI
Angina Pectoris is described as? - ANSWER - Chest pain, Left-Sided chest
pain.
- Pain may radiate down left arm, upper back, upper abdomen area, and jaw
How many types of Angina Pectoris? - ANSWER 3: Stable, Unstable, and
Variant
