Anatomy/Physiology
Rapid depolarization correlates with this ECG waveform
QRS complex
The gain control provides what function
Amplification of returning echoes
The primary factor causing systemic HTN is
Increased peripheral resistance
Symptoms associated with this cardiomyopathy may only be experienced during exercise
Hypertrophic
When a wall motion abnormality lasts for 24-72 hours but has not had irreversible damage it is referred to as
Stunned
The area of the heart where the coronary sulcus meets the interventricular sulcus is called
Crux
The intensity of the sound beam is controlled by
Transmit power
In patients with chronic HTN the ascending aorta should be evaluated for?
Dilation or aneurysm
The most common cause of a restrictive cardiomyopathy is
Amyloidosis
When the heart wall has absent inward wall motion and lacks systolic thickening it is said to be
Akinetic
The left ventricular outflow tract ends at the level of the
Aortic annulus
A "B" bump or notch on the MV M-mode tracing may indicate
Elevated LV end diastolic pressure
Pulmonary artery pressure is considered elevated when it reaches which minimal level?
>30mmHg
Because of the infiltrative process of the restrictive CM the myocardium may appear?
Increased in echogenicity
The period of time when flow between the LA and LV equalizes is
Diastasis
The cardiac structure that forms the right lateral cardiac border is the
Right atrium
TMitral valve prolapse may be augmented by having the patient
Perform a valsalva maneuver
Patients in pulmonary HTN may display this on the M-mode of the pulmonic valve?
Absent "a" wave or flying "W" pattern
One of the most well-known cardiac complications in patients with lupus erythematosus is
Libman-Sach's endocarditis
The most common location for an aeurysm to occur is the
LV apex
Where are the pectinate muscles located in the LA
LA Appendage
Inhaling amyl nitrate may help to provoke or enhance
MVP or Sub aortic stenosis obstruction
Determine the RVSP with the given information:
TR velocity 2.8 m/sec
36mmHg
A cardiomyopathy brought on by emotion or physical stress that causes apical ballooning of the LV best describes
Takotsubo CM
What component of echo is most helpful in the diagnosis of a pseudoaneurysm
Color flow imaging
