Correlation between the extent of CTD and the parameters of LV mechanical asynchrony

Parameter	Coefficient of correlation	p
Cv r-EF (at rest), %	0.56	< 0.01
dT (at rest), ms	0.53	< 0.01
Δ Cv r-EF, %	0.40	< 0.05
Δ dT, ms	0.52	< 0.01

Cv r-EF – variation coefficient of 12 r-EF, dT – RMS by 12 LV regional durations of systolic motion, Δ Cv-rEF – increment between Cv r-EF before and after exercise-test, Δ dT – increment between dT before and after exercise test.
