Do presenting rhythm in sudden deaths temporally proximate to discharge of TASER conducted electrical weapons?
In sudden deaths proximate to CEW discharge, immediate collapse is unusual, and VF is an uncommon VF presenting rhythm. Within study limitations, including selection bias and the possibility that VF terminated before the presenting rhythm was recorded, these data do not support electrically induced VF as a common mechanism of these sudden deaths.
Displacement index is linearly related to EF and also to other parameters of longitudinal systolic function. Displacement index has some advantages over Sz for assessing ventricular systolic function and should prove useful in measuring longitudinal and global LV systolic function.
