AND STRUCTURED LEARNING GUIDE FULL
COVERAGE
◉ 2 of 6. Answer: Which of the following grades represents a
murmur that is most faint
◉ Pulmonic insufficiency. Answer: Which of the following flow
patterns is most likely to be the longest
◉ False. Answer: True or false the hemodynamic evaluation of MR is
performed during diastole
◉ False. Answer: True or false the hemodynamic evaluation of aortic
stenosis is performed during diastole
◉ True. Answer: True or false the hemodynamic evaluation of
tricuspid stenosis is performed during diastole
◉ True. Answer: True or false hemodynamic evaluation of pulmonic
regurgitation is performed during diastole
◉ Phase 0- depolarization rapid influx of sodium.
,Phase 1- Repolarization potassium exits cell.
Phase 2- excitation contraction influx of calcium.
Phase 3-early repolarization sodium/potassium pump -sodium &
potassium are pumped out.
Phase 4 - resting membrane potential- sodium & calcium remain
outside of cell -- potassium remain inside.. Answer: Action potential
◉ Mitral SV-Aortic SV / mitral SV x 100%
Aortic SV - Mitral SV / aoryic SV x 100%. Answer: Mitral & Aortic
Regurgitation fraction
◉ Decreases
Sympathetic - atria & ventricles
Parasympathetic- vagus nerve mostly atrial. Answer: How does
vagus nerve stimulation affect the HR?
◉ Always Regurgitant lesion is first.. Answer: MR or AS which will be
first?
◉ First- closure of Mitral & tricuspid valves
Second - closure aortic A2 & pulmonic P2 valves
Third - early diastolic ventricular inflow
, Fourth - atrial contraction. Answer: Heart Sounds
◉ 4th. Answer: Patient with A-fib what heart sound is missing?
◉ Anterior interventricular sulcus. Answer: Where does the LAD
originate?
◉ Power (watts)
---------------
Beam area (cm)^2. Answer: Intensity equation
◉ (Amplitude) ^2 =dB. Answer: Power equation
◉ Wavelength mm= propagation speed / frequency
1.54/frequency =wavelength mm. Answer: Wavelength equation
◉ # cycles in a pulse x period = Pulse Duration (us). Answer: Pulse
duration equation
◉ # of cycles x wavelength mm= SPL mm. Answer: SPL equation
