🗑
|
||||
| What are the 3 types of angina? | stable, prinzmetal, and unstable
🗑
|
||||
| What is stable angina is relieved by? | rest and NTG (vasodilation and decreased workload)
🗑
|
||||
| Is prinzmetal angina predictable or unpredictable and why? | unpredictable; may be due to spasms
🗑
|
||||
| What is a myocardial infarction (MI)? | prolonged or total disruption of blood flow to myocardium causing irreversible cellular death
🗑
|
||||
| What is a transmural infarct? | involves entire ventricular wall thickness, common & severe, nearly all are in L ventricular wall
🗑
|
||||
| Describe subendocardial infarction. | less severe, most vulnerable to a reduction in blood flow, only portion of ventricular wall involved
🗑
|
||||
| True or false, the septum separates the heart into right and left sides. | True
🗑
|
||||
| List the 4 heart chambers. | Right atrium and ventricle; left atrium and ventricle
🗑
|
||||
| List the 2 valves on the right side of the heart. | Pulmonary and tricuspid
🗑
|
||||
| List the 2 valves on the left side of the heart. | Aortic and mitral (aka bicuspid)
🗑
|
||||

🗑
|
||||
| The left side of the heart returns blood to the body via __________? | aorta
🗑
|
||||
| Narrowing or stricture of a blood vessel is known as? | stenosis
🗑
|
||||

🗑
|
||||
| What is the most common septal defect? | Ventricular septal defect (VSD)
🗑
|
||||
| What is VSD? | an acyanotic (congestive) defect, opening b/t ventricles, produces increased workload for R side of heart
🗑
|
||||
| What kind of shunt/problems occur in VSD? | L-to-R shunt, w/ continued high pulm blood flow, pulm vascular obstructive disease develops; can eventually lead to shunt reversal and cyanotic sympotms
🗑
|
||||
| What is transposition of great arteries? | Aorta comes from R ventricle and pulmonary artery from L ventricle; resulting in 2 separate, non-communicating circulations =

🗑
|
||||
| What is RAA? | Renin-Angiotensin-Aldosterone System
🗑
|
||||
| What happens if the RAA system is activated? | If this system is activated, the following occurs:
vasoconstriction
increase BP
hold on H2O & Na+
🗑
|
||||
| What are cardiac shunts? | they create an abnormal blood flow path
🗑
|
||||
| What occurs with a right to left shunt? | unoxygenated blood from the right side of heart enters the left and systemic circulation
child may have cyanosis
🗑
|
||||
| What occurs with a left to right shunt? | oxygenated blood from left side of heart enters the right and is re-circulated through the lungs
acyanotic defect
right side has increased workload due to extra blood, over time right ventricular hypertrophy may occur
🗑
