Xa kuvela iimpawu zokuqala zesifo senhliziyo, kufuneka uhlale unxibelelana nengcali. Inokwenzeka ukuba, ukucacisa isizathu seengxaki, inkqubo efana ne-myocardial scintigraphy iya kumiselwa. Le ndlela ikuvumela ukuba uhlolisise ukuhamba kwegazi, uvavanye imeko ye-myocardium kunye neqondo lokunikezelwa kwegazi.
Ukhawuleza nini?
Isifo senhliziyo sisona sizathu esiqhelekileyo sokufa namhlanje. Ngelishwa, ngokukhawuleza isigqithiso sobomi, ngokungaqhelekanga okungaqhelekanga kwindlela eqhelekileyo yokuphupha kunye nokuhanjiswa kweenkonzo eziphambene nomsebenzi wesimo senhliziyo. Ukuthintela ukuphuhliswa kwezifo ezibi kakhulu, ngexesha elizeleyo uphantsi kweemviwo kunye nokwenza umtsalane we-myocardium.
Le ndlela yophando yenza ukuba kubekho ummandla we-myocardial ischemia. Kwiimifanekiso ezifunyenweyo ngexesha le nkqubo, indawo ebonakalayo ebomini ebonakalayo kubantu ababesinda kwintliziyo yesifo kunye nommandla wokunikezela ngegazi kwi-myocardium kubonakala ngokucacileyo.
I-Perfusion scintigraphy ye-myocardium inokuqhutywa kunye nomthwalo kwaye kwindawo yokuphumla okupheleleyo. Inkqubo ibelwe kwimiba elandelayo:
- I-Scintigraphy isetyenziswa rhoqo ngexesha lokuxilongwa kwe- angina pectoris .
- Inkqubo inceda ukuvavanya ukuphumelela kwonyango lwenkqubo ye-cardiovascular system.
- Ngaphambi kokuba uqalise unyango, ukucwiliswa kukuvumela ukuba uhlole zonke iingozi ezikhoyo ezinzima.
Ukulungiselela ukucwiliswa kwe-perfusion kunye nezindlela zophando
Isifundo esizodwa asifunanga. Kucetyiswa phambi kwenkqubo yokuphepha nokusela nokusela iziphuzo ze-caffeinated. Ukuze isigulane siziva sikhululekile, kuyacetyiswa ukuba sigqoke iimpahla ezifanelekileyo zokubhalela iimviwo. Ukucima okanye ukunciphisa ukusetyenziswa kweziyobisi kwiimeko ezininzi, akukho mfuneko.
Ukufunda ngokuphumla, i-technetium ene-radioactive yongezwa kumzimba wesigxina ngokudibanisa nesicatshulwa esiphathwe kakuhle kwi-myocardium. I-Myocardial scintigraphy kunye nomsebenzi owenziwa emva kwexesha lokuqala lokufunda. Kule meko, yonke imirhumo imiselwe yikhamera ekhethekileyo yekhamera kunye neziphumo kwiikrini.
Inkqubo yokwakheka kwintlanzi ayinakulimala ngokupheleleyo. Nangona ngexesha lophando kunye nezinto ezisetyenziselwa i-radioactive, impembelelo yabo emibi emzimbeni awuncinci. Ukufumana iziphumo ezichanekileyo zesifundo, ukucwiliswa kwe-perfusion ye-myocardium kukucetyiswa ukuba kudibaniswe ne-tomography.
