Cardiac Testing Flashcards
where to start in cardiac testing?
comprehensive history and physical
EKG:
good to test for what?
arhythmias conduction disturbances MI susceptibility to sudden cardiac death sructural abnormailities
continuous or intermediate cardiac monitor worn by pts for a period of time, “event monitor”, they can press a button a when symptoms are experienced
holter montior
implantable device that can monitor a pt for years to capture arrthytmias for years
loop recorder
helps evaluate changes in BP and HR based on position of body?
tilt table
used to evulate vertigo/syncope?
tilt table
isoproternenol, nitrates and adenosine are used to induce orthoatatic changes and provoke arrythmias
tilt table
US to create images of chambers, valves, great vessels and function/motion of the heart
US
TRANSTHORAIC OR TTE
TRANSESOPHGEAL OR TEE
WHICH IS ROUTINE?
TTE or transthoracic
used to created detailed images of the posterior heart
TEE ECHO
a TEE echo can help see what?
left artial thrombus, small mitral valve regurges, throacic aortic dissections
used to determine flow rate of blood through heart?
ECHO DOPPLER
chamber size and wall motion can be assessed during this?
echo
wall mostion abnormailties are a sign of what?
ischemia
dilated chambers a sign of what?
systolic HF
ventricular hypertrophy a sign of what?
diastolic hypertrophy
end diastolic vs end systolic give you what?
ejection fraction
uses radioactive contrast to enhance images or valves, EF and wall motion
MUGA
used to detect ischemia when there is otherwise no ischemia at rest?
stress test
assess significance of known CAD?`
stress test
adenosine, regadensoine, dipyridamole, dobutamine, isoproterenol are all used in what?
pharmacologic stress tx
what should be used during every stress test?
EKG
on echo stress tx we are looking for what?
signs of ischemia after indicing stress (once during exercise and once after)
echo stress tests look for ischemia: more specifically change in what two things?
wall motion
ejection fraction
