Formula
TV_EF
Tricuspid Valve E-F
Velocity
one slope
TV_EF=v1[cm/s or m/s]
TV_DE
Tricuspid Valve D-E
Amplitude
one distance
TV_DE=d1[cm or mm]
TV_CE
Tricuspid Valve C-E
Amplitude
one distance
TV_CE=d1[cm or mm]
TV_AC
Tricuspid Valve A-C
Interval
one time interval
TV_AC=t1[msec or sec]
P-R
P-R Interval
one time interval
P-R=t1[msec or sec]
HR
Heart Rate (beats/minute)
one 2 beat time
interval
HR[BPM]=120 [sec]/ 2
beat time [sec]
TV-A/E
Tricuspid Valve A/E Ratio
one distance (TV<D-E>)
TV-A/E[%]= (D<TV_AC>/
TV_DE) x 100
TPR-AC
Tricuspid Valve PR-AC
Interval
two time intervals
TPR-AC[ms or sec]= P-R
- TV_AC
Table 4–23. Tricuspid Valve (M-TV)
TV_AC measurement calculates D_AC simultaneously.
TV_DE, TV_EF, TV_AC and TV_CE measurement results
should be performed through the slope measurement.
