Asystole (daga Sabon Latin, daga Girkanci a- 'a'a', 'ba tare da' + systolē 'ƙuntatawa' ) shine rashin raguwar ventricular a cikin mahallin mummunan zuciya, ya bambanta da asystole da aka haifar a kan mai haƙuri mai sanyaya a kan na'urar zuciya- huhu, da kuma anesthesia gaba ɗaya yayin tiyata da ke buƙatar dakatar da zuciya. Asystole shine mafi munin nau'in dakatar da zuciya kuma yawanci ba za a iya juyawa ba. Har ila yau ana kiranta da flatline na zuciya, asystole shine yanayin dakatar da aikin lantarki gaba ɗaya daga zuciya, wanda ke nufin babu raguwar nama daga tsokoki na zuciya sabili da haka babu jini zuwa sauran jiki.

Bai kamata a rikita asystole tare da ɗan gajeren hutu a ƙasa da sakan 3 a cikin aikin lantarki na zuciya wanda zai iya faruwa a wasu sautin da ba su da tsanani. Asystole ya bambanta da kyawawan abubuwan da suka faru na ventricular fibrillation, kodayake dukansu suna da mummunan hangen nesa, kuma VF mai kyau wanda ba a kula da shi ba zai haifar da asystole. Ya kamata a kawar da rashin amfani da waya, katsewar wutar lantarki da jagora, da kuma katsewar wutar.

Marasa lafiya na asystolic (kamar yadda ya saba da waɗanda ke da "rashin ƙarfi" kamar su fibrillation mai laushi ko mai kyau na ventricular, ko kuma unstable Ventricular tachycardia wanda ba ya samar da bugun jini, wanda za'a iya magance shi da defibrillation) yawanci yana nan tare da mummunan hangen nesa. An samo Asystole da farko a cikin kusan kashi 28% na lokuta na kama zuciya a cikin marasa lafiya da ke asibiti, amma kashi 15% ne kawai daga cikin waɗannan suka tsira, koda tare da amfanin sashin kulawa mai tsanani, tare da ƙarancin (6%) ga waɗanda aka riga aka ba da magungunan don hawan jini.

Ana kula da Asystole ta hanyar cardiopulmonary resuscitation (CPR) tare da vasopressor na intravenous kamar epinephrine (adrenaline). Wani lokaci ana iya gano wani dalili mai juyawa kuma a kula da shi (wanda ake kira "Hs da Ts", misali wanda shine hypokalaemia). Yawancin abubuwan da aka ba da shawarar a baya - kamar su defibrillation (wanda aka sani ba shi da tasiri a kan asystole, amma a baya an yi shi idan rhythm ya kasance mai kyau sosai ventricular fibrillation) da kuma intravenous atropine - ba sa cikin ka'idojin yau da kullun da yawancin manyan hukumomin duniya suka ba da shawarar.
