Hyperplasia
|
Increasing the amount of cells
|
|
|
IVS

LVID
|
Left Ventricle Inner Dimension
|
|
|
LVPW
|
Left Ventricular Posterior wall
|
|

|
|
Hypokinesis
|
Diminished or abnormally slow movement
|
|
|
Tardokinesis
|
A segment of the myocardium with a delayed contraction
|
|
|
Equation for calculating Index of Hypertrophy
|
Hypertrophy Index = (LVPW+IVS)/LVID
|
|
|
Is a hypertrophy index of .30, pathological or physiological?
|
physiological
|
|
|
Is a hypertrophy index of .50, pathological or physiological
|
pathological
|
|
|
Most common acquired heart disease
|
CAD - Coronary Artery Disease
|
|
|
Akinesis
|
No contraction, occurs after an MI, tissue death occurring
|
|
|
Dyskinesis
|
tissue moving in the opposite direction, due to the pressures produced by the good myocardium contracting into the area of the MI, possible onset of a aneurysm
|
|
|
Two conditions that affect wall motion and are unrelated to an MI
|
LBBB, and period after cardiac surgery
|
|
|
What type of BBB makes the right ventricle contract before the left ventricle?
|
LBBB
|
|
|
Differentiation between an MI and a LBBB
|
In a LBBB, myocardial thickening is typically preserved as is initial early ventricle contraction.
|
|
|
What area of the LV contracts slightly after the septal region
|
Inferoposterior and Lateral walls
|
|
|
Eccentric hypertrophy is seen in lesions to what structures?
|
Valvular structures
|
|
|
Disease that can lead to false measurements of left ventricular function?
|
CAD
|
|
|
Systolic wall thickening and velocity of circumferential shortening is assessed on... What mode?
|
M-Mode
|
|
|
What is Descent of Base?
|
When the base of the heart moves towards the apex as a result of the heart contracting
|
|
|
What is Strain Rate Imaging?
|
rate of change in velocity between two points, doppler principles for evaluating regional wall motion
|
|
|
Acquired disease
|
not present at birth
|
|
|
Organic disease
|
A disease in which there is a structural change to some tissue or organ of the body.
|
|
|
Equation for Fractional Shortening
|
(LVIDd-LVIDs)/LVIDd
|
|
|
T/F An increase fractional shortening will decrease the EPSS?
|
False
|
|
|
In M-Mode of the Aortic valve, A decrease in forward stroke volume will resemble what shape?
|
Bullet shape
|
