HR for bradycardia
< 60 bpm
IVS and LPVW measurement
< 1.2 cm
during systole, walls should thicken and contract about _____ towards the center of the chamber
20-30%
what is the best stressor
exercise
percentage of ventricular filling attributing to early rapid passive filling
70-75%
sawtooth pattern shape indicates what type of dysrhythmia
A flutter
graph sweep speed =
50 mm/sec
the LAD supplied blood to the following LV walls
septal wall, anterior wall and apical wall
what is the main reason to do an TTE
To evaluate the EF
20 bpm
3 PVCs or more in a row with a rapid heart rate usually about 150-250 bpm
V tach
holosystolic measurement
> 3 mm
decreased systolic function associated symptoms include
SOB, DOE, CP
If the heart rate does not increase enough, what other pharmacological agent may be given
atropine
which two grades are associated with a thrill murmur
V and VI
arrhythmia due to LAE, No P wave and no 4th heart sound
A- fib
if you have a diastolic flutter of the AMVL caused by AI
wall motion score for dyskinetic wall
4
the left side uses what type of approach
pig tail catheter
a patient with a systolic ejection murmur and a diminished A2 has a?
aortic stenosis
Electrical impulse originating in the atria outside of the SA node. Produces an abnormal P wave earlier than expected
PAC (premature atrial contraction)
Increased A wave on the PV m-mode indicate
pulmonic stenosis
CX follows the _____ _____ to the _____ aspect of the heart
atrioventricular groove, posterior
