Boholo ba khatello ea diastolic e bontša matla ao khatello ea mali e hatellang methapo ka nako ea ha mesifa ea pelo e phutholohile ka ho feletseng (nakong ea diastole), e.g. ha pelo e phomotse. Ena ke khatello e tlaase ka ho fetisisa meleng ea methapo ea mali, e nang le mali lithong le lithong tse nyenyane, tse itšetlehileng ka ho toba ka mokokotlo oa li-vascular le elasticity. Ho feta moo, tekanyo ea mali le molumo oa pelo li ameha ho thehoa ha khatello ea khatello ea diastolic.
Ka tloaelo, ho batho ba phetseng hantle, boemo ba khatello ea diastolic bo fapana pakeng tsa 65 ± 10 mm Hg. Ha u se u le lilemong, botle bona bo fapana hanyenyane.
