AUSTRALIAN CATHOLIC UNIVERSITY PHTY208
WEEK 6-12 KEY EXAM CONCEPT 2025 ALREADY
GRADED A+ SOLVED
how does a hyertrophic cardomyopathy cause HF
genetically determined L ventricular hypertrophy + disproportional thickening of ventricular
septum
what are the 4 types of pericardial disorder
1. pericarditis
2. pericardial effusion
3. cardiac temponade
4. constructive pericarditis
what is pericarditis
acute inflammation of the pericardium
list some respiratory physiological differences of infants from adults
1. decreased lung compliance
2. decreased lung capacity (for deep breath)
3. more slow twitch (Type 1) muscle fibres --> cannot maintain increased BR
4. increased metabolic rate
what is atherosclerosis
build-up of calcium deposits and fatty substances in arteries --> leading to plaque formation. Reduces
size of vessels or causes blockage - reduced BF
list some respiratory anatomic differences of infants from adults
, 1. smaller airway diameter
2. comparative heart size (less space for lungs)
3. cylindrical chest wall cross-sectional shape
4.soft ribs
5. no bucket handle
6. diaphragm horizontal angle of insertion
7. weaker intercostals
8. preferential nose breathers
what causes an acute coronary syndrome
ruptured plaque resting in coronary thrombosis, reduced blood flow --> myocardial cell death
what is STEMI
thrombus completely blocks coronary artery --> ST elevation myocardial infarction --> promp
recognition to ensure reperfusion soon after presentation
what is a Non-STEMI
thrombus partly blocs coronary artery --> part of heart muscles being supplied die --> no ST elevation
(can detect with cardiac enzymes)
what is a cardiomyopathy
disease of myocardium associated with mechanical and/or electrical dysfunction (lead to HF)
what are the two cardiomyopathy causing HF
1. dilated cardiomyopathy
2. hypertrophic cardiomyopathy
how does dilated cardiomyopathies cause HR
ventricular enlargement with a reduction in ventricular wall thickness = decreased contractile force =
imparied pump function
risk factors for atherosclerosis
