PW Tricuspid valve
What is the normal duration range for deceleration time?
100-240 ms
This measurement is relevant for assessing valve function.
What type of waves should be traced for MV VTI after the valve?
Biphasic waves
Continuous wave Doppler is used for this tracing.
What is the normal PHT value for the medial septal annulus?
20-80 ms
PHT stands for pressure half-time, an important measure in echocardiography.
What is the typical measurement for VT1?
~10-13 cm
VT1 refers to the velocity time integral, a parameter used in echocardiography.
What is the normal S’ value for the lateral septal annulus?
210 cm/s
S’ is a measure of myocardial velocity.
What is the normal range for S in pulmonary vein assessments?
~0.4 - 0.7 m/s
This measures the velocity of blood flow in the pulmonary veins.
What is the normal AR duration?
≤150 ms
AR stands for atrial reversal, an important measure in assessing diastolic function.
Fill in the blank: The normal D value for pulmonary veins is approximately _______.
~0.3 - 0.6 m/s
D refers to diastolic flow velocity.
What is the significance of measuring the medial and lateral septal annulus?
To assess normal valve function
These measurements help evaluate the function of the heart valves.
True or False: The normal value for AR peak is ≤0.35 m/s.
True
This is critical for understanding diastolic function in echocardiography.
