Yintoni uvavanyo loxinzelelo lwethallium?

Uvavanyo loxinzelelo lwe-thallium luvavanyo lwe-imaging yenyukliya ebonisa ukuba igazi lingena njani entliziyweni yakho ngelixa usenza umthambo okanye uphumle. Olu vavanyo lukwabizwa ngokuba luvavanyo lwentliziyo okanye lwenyukliya.

Ngexesha lenkqubo, ulwelo olunomthamo omncinci womsakazo obizwa ngokuba yi-radioisotope ulawulwa komnye wemithambo yakho. Irediyo iya kuhamba ngokuhamba kwegazi lakho kwaye iphele entliziyweni yakho. Nje ukuba imitha isentliziyweni yakho, ikhamera ekhethekileyo ebizwa ngokuba yikhamera ye-gamma iyakwazi ukubona imitha kwaye ityhile nayiphi na imiba enayo imisipha yentliziyo yakho.

Ugqirha wakho unokuyalela uvavanyo lwe-thallium ngezizathu ezahlukeneyo, kubandakanya:

• ukuba barhanela ukuba intliziyo yakho ayifumani gazi laneleyo xa uphantsi koxinzelelo- umzekelo, xa usenza umthambo
• ukuba unentlungu esifubeni okanye i-angina eyandayo
• ukuba ukhe wahlaselwa yintliziyo ngaphambili
• ukujonga ukuba asebenza njani amayeza
• ukumisela ukuba ngaba inkqubo okanye utyando lube yimpumelelo
• Ukuchonga ukuba ingaba intliziyo yakho isempilweni ngokwaneleyo na ukuba ungaqalisa inkqubo yomthambo

Uvavanyo loxinzelelo lwe-thallium lunokubonisa:

• ubukhulu begumbi lakho lentliziyo
• isebenza kakuhle kangakanani iimpompo zentliziyo yakho-oko kukuthi, umsebenzi wayo we-ventricular
• ukuba imithambo yegazi yakho iyinika njani kakuhle igazi lakho, elaziwa njenge-myocardial perfusion
• ukuba izihlunu zentliziyo yakho zonakele okanye zonzakele kuhlaselo lwentliziyo lwangaphambili

Uvavanyo loxinzelelo lwethallium lwenziwa njani?

Uvavanyo kufuneka lwenziwe esibhedlele, kwiziko lonyango, okanye kwiofisi kagqirha. Umongikazi okanye ingcali yezempilo ifaka umgca we-intravenous (IV), oqhelekileyo ngaphakathi kwengqiniba yakho. I-radioisotope okanye amayeza e-radiopharmaceutical, anje nge thallium okanye i-sestamibi, ajojowe nge-IV.

Izinto ezinemitha ye-radio ziphawula ukuhamba kwegazi lakho kwaye zithathwa yikhamera ye-gamma.

Uvavanyo lubandakanya umthambo kunye nenxalenye yokuphumla, kwaye intliziyo yakho ifotwe phakathi kokubini. Ugqirha olawula uvavanyo lwakho uya kumisela indlela eziqhutywa ngayo ezi mvavanyo. Uyakufumana inaliti yeyeza phambi kwesahlulo ngasinye.

Inxalenye yokuphumla

Ngethuba le nxalenye yovavanyo, ulala phantsi kangangemizuzu eli-15 ukuya kwengama-45 ngelixa izinto ezinemitha yeathom esebenza ngendlela yomzimba wakho ukuya entliziyweni yakho. Nilale phantsi kwetafile yoviwo iingalo zenu zingasentla kwentloko yenu, kwaye ikhamera ye-gamma ngentla kwenu ithatha imifanekiso.

Yenza umthambo

Kwisahlulo somthambo wovavanyo, uhamba kwi-treadmill okanye unyoboza ibhayisekile yomthambo. Kungenzeka, ugqirha wakho uya kukucela ukuba uqale kancinci kwaye ngokuthe ngcembe uthathe isantya kwijog. Kuya kufuneka ubaleke uthambekele ekwenzeni ukuba kube nzima ngakumbi.

Ukuba awukwazi ukwenza umthambo, ugqirha wakho uya kukunika iyeza elivuselela intliziyo yakho kwaye liyenze ibethe ngokukhawuleza. Oku kulingisa indlela eya kwenza ngayo intliziyo yakho ngexesha lokuzilolonga.

Uxinzelelo lwegazi kunye nesingqi sentliziyo zijongwa ngelixa uzilolonga. Nje ukuba intliziyo yakho isebenze nzima kangangoko, uya kuphuma kwitreadmill. Emva kwemizuzu emalunga nama-30, uya kulala phantsi kwitafile yeemviwo kwakhona.

Ikhamera ye-gamma emva koko irekhoda imifanekiso ebonisa ukuhamba kwegazi ngentliziyo yakho. Ugqirha wakho uya kuthelekisa le mifanekiso kunye neseti yemifanekiso yokuphumla ukuvavanya ukuba buthathaka kangakanani okanye lomelele kangakanani ukuhamba kwegazi entliziyweni yakho.

Ukulungiselela njani uvavanyo loxinzelelo lwe-thallium

Kuya kufuneka ukuba ukhawuleze emva kobusuku ezinzulwini zobusuku ngaphambi kovavanyo okanye ubuncinci iiyure ezine ngaphambi kovavanyo. Ukuzila ukutya kunokuthintela ukugula ngexesha lesabelo somthambo. Nxiba iimpahla ezifanelekileyo nezihlangu xa uzilolonga.

Iiyure ezingamashumi amabini anesine phambi kovavanyo, kuyakufuneka uphephe yonke icaffeine, kubandakanya iti, isoda, ikofu, itshokholethi - ikofu kunye neziselo ezinetafisi, ezinamanani amancinci e-caffeine- kunye nokunciphisa iintlungu ezithile. Ukusela i-caffeine kunokubangela ukuba izinga lokubetha kwentliziyo yakho liphezulu kunesiqhelo.

Ugqirha wakho kuya kufuneka azi onke amayeza owathathayo. Kungenxa yokuba amanye amayeza afana nalawo anyanga isifuba-anokuphazamisa iziphumo zakho zovavanyo. Ugqirha wakho uya kufuna ukwazi ukuba uthathe nawaphi na amayeza e-erectile dysfunction kubandakanya i-sildenafil (Viagra), tadalafil (Cialis), okanye vardenafil (Levitra) iiyure ezingama-24 phambi kovavanyo.

Umngcipheko kunye neengxaki zovavanyo loxinzelelo lwe-thallium

Uninzi lwabantu luyalunyamezela uvavanyo loxinzelelo lwe-thallium kakuhle. Unokuziva ulwamvila njengoko iyeza elinganisa umthambo lifakwa, lilandelwe yimvakalelo efudumeleyo. Abanye abantu banokuba nentloko ebuhlungu, isicaphucaphu, kunye nentliziyo ebalekayo.

Izinto ezinokusasazeka ngemitha ziya kuwushiya umzimba wakho kumchamo wakho. Iingxaki ezivela kwimathiriyeli enemitha ye-radio efakwe emzimbeni wakho zinqabile.

Iingxaki ezinqabileyo kuvavanyo zingabandakanya:

• i-arrhythmia, okanye ukubetha kwentliziyo okungaqhelekanga
• ukwanda kwe-angina, okanye iintlungu zokungahambi kakuhle kwegazi entliziyweni yakho
• ubunzima bokuphefumla
• iimpawu ezifana nesifuba
• ukujija okukhulu koxinzelelo lwegazi
• irhashalala
• ukuqhawukelwa ngumphefumlo
• Ukungonwabi esifubeni
• isiyezi
• ukubetha kwentliziyo, okanye ukubetha kwentliziyo okungavumelekanga

Yazisa umlawuli wovavanyo ukuba ufumana naziphi na kwezi mpawu kuvavanyo lwakho.

Zithetha ntoni iziphumo zovavanyo loxinzelelo lwe-thallium?

Iziphumo zixhomekeke kwisizathu sovavanyo, ukuba umdala kangakanani, imbali yakho yeengxaki zentliziyo, kunye neminye imiba yezonyango.

Iziphumo eziqhelekileyo

Iziphumo eziqhelekileyo zithetha ukuba ukuhamba kwegazi kwimithambo yegazi entliziyweni yakho kuqhelekile.

Iziphumo ezingaqhelekanga

Iziphumo ezingaqhelekanga zingabonisa:

• ukunciphisa ukuhamba kwegazi kwinxalenye yentliziyo yakho okubangelwa kukucuthwa okanye ukuvaleka kwemithambo enye okanye nangaphezulu enika izihlunu zentliziyo yakho
• ukonakala kwentliziyo yakho ngenxa yokuhlaselwa sisifo sentliziyo sangaphambili
• isifo sentliziyo
• Intliziyo enkulu kakhulu, ebonisa ezinye iingxaki zentliziyo

Ugqirha wakho unokufuna uku-odola kuvavanyo oluninzi ukumisela ukuba unesimo sentliziyo. Ugqirha wakho uya kuphuhlisa isicwangciso sonyango ngokukodwa kuwe, ngokusekwe kwiziphumo zolu vavanyo.
