Because everyone is convinced it stops the heart, I don't doubt it does. However I just can't source it.

@NewGenTV  As for the rate, it takes "seconds" to kill the target. Esdeath seemed to have longer though, but maybe that was because the blade was already destroyed. In the anime it seems that plot relevance slows down the curse's effects. :-)
