another CVS review Flashcards
why does chest pain with angina come on with exercise
blood flow through left coronary artery because diastole is shorter
flow in the left coronary artery occurs mainly in
diastole
how does a beta blocker alleviate myocardial ischaemia
reduce heart rate and force of contraction to reduce oxygen demand and improve perfusion of coronary arteries
what does GTN spray do
dilate systemic veins
what findings would be consistent with unstable angina
ST depression and normal troponin levels
ST elevation in leads 1, aVL, V5 and V6 suggests
lateral STEMI
which findings would be consistent with an acute anterolateral NSTEMI
ST depression in leads 1, aVL, V3, V4, V5 and V6 and presence of troponins
A man with congestive heart failure develops pulmonary oedema due to raised hydrostatic pressure in the pulmonary capillaries. Why
increased left atrial pressure
best medications for heart failure and pulmonary oedema
ACEi and diuretics
what would you hear on auscultation of heart in a patient with aortic stenosis
systolic murmur in 2nd intercostal space to right of sternum
what would you hear on auscultation of a patient with mitral valve stenosis
diastolic murmur in 5th intercostal space in midclavicular line on the left
cause of lubdub
AV valves opening and closing
man is stabbed and bleeding out, what will his aBP, CVP and TPR be
aBP and CVP low, TPR high
man stabbed in chest with little bleeding. What type of shock. veins in neck distended
mechanical
high CVP- cardiac tamponade
