Uvavanyo loxinzelelo lwenyukliya

Uvavanyo loxinzelelo lwenyukliya yindlela yokucinga esebenzisa izinto ezinemitha ye-radio ukubonisa ukuba igazi lihamba njani kakuhle kwintliziyo, ekuphumleni nasekusebenzeni.

Olu vavanyo lwenziwa kwiziko lonyango okanye kwiofisi yomboneleli wezempilo. Yenziwa ngokwamanqanaba:

Uya kuba nomgca we-intravenous (IV).

• Into ene-radioactive, efana ne-thallium okanye i-sestamibi, iya kutofelwa komnye wemithambo yakho.
• Uya kungqengqa ulinde phakathi kwemizuzu eli-15 ukuya kwengama-45.
• Ikhamera ekhethekileyo iyakuskena intliziyo yakho kwaye yenze imifanekiso ukubonisa indlela into ehambe ngayo egazini lakho nakwintliziyo yakho.

Uninzi lwabantu luya kuhamba ngeenyawo kwitreadmill (okanye i-pedal kumatshini wokuzilolonga).

• Emva kokuba i-treadmill iqala ukuhamba kancinci, uya kucelwa ukuba uhambe (okanye unyohlise) ngokukhawuleza kwaye uthambekele.
• Ukuba awukwazi ukwenza umthambo, unganikwa iyeza elibizwa ngokuba yi-vasodilator (njenge-adenosine okanye i-persantine). Eli chiza landisa (yandisa) imithambo yentliziyo yakho.
• Kwezinye iimeko, unokufumana iyeza (dobutamine) eya kwenza ukuba intliziyo yakho ibethe ngokukhawuleza kwaye ibenzima, efanayo naxa usenza umthambo.

Uxinzelelo lwegazi kunye nesingqisho sentliziyo (ECG) luya kujongwa kulo lonke uvavanyo.

Xa intliziyo yakho isebenza nzima kangangoko inako, into ene-radioactive iphinde ingene kwenye yemithambo yakho.

• Uya kulinda imizuzu eyi-15 ukuya kwengama-45.
• Kwakhona, ikhamera ekhethekileyo iya kuskena intliziyo yakho kwaye yenze imifanekiso.
• Unokuvunyelwa ukuba uphakame phezu kwetafile okanye isitulo kwaye ube nokutya okanye isiselo.

Umboneleli wakho uya kuthelekisa iseti yokuqala neyesibini yemifanekiso usebenzisa ikhompyuter. Oku kunokunceda ukufumanisa ukuba unesifo sentliziyo okanye ukuba isifo sentliziyo siyanda.

Kuya kufuneka unxibe iimpahla ezifanelekileyo kunye nezihlangu ezinee-non-skid. Unokucelwa ukuba ungatyi okanye usele emva kobusuku. Uya kuvunyelwa ukuba neesiphu ezimbalwa zamanzi ukuba ufuna ukuthatha amayeza.

Kuya kufuneka uyiphephe icaffeine kangangeeyure ezingama-24 phambi kovavanyo. Oku kubandakanya:

• Iti nekofu
• Zonke ii-sodas, nkqu nezo zibhalwe i-caffeine-yasimahla
• Iitshokholethi, kunye nokunciphisa iintlungu ezithile eziqukethe icaffeine

Amayeza amaninzi anokuphazamisa iziphumo zovavanyo lwegazi.

• Umboneleli wakho uya kukuxelela ukuba ngaba ufuna ukuyeka ukuthatha nawaphi na amayeza phambi kokuba wenze olu vavanyo.
• SUKUYEKE ukutshintsha okanye utshintshe amayeza akho ngaphandle kokuthetha nogqirha wakho kuqala.

Ngexesha lovavanyo, abanye abantu baziva:

• Iintlungu zesifuba
• Ukudinwa
• Iintlanzi zemisipha emilenzeni okanye ezinyaweni
• Ukuqhawukelwa ngumphefumlo

Ukuba unikwe ichiza le-vasodilator, unokuziva ulwamvila njengoko kufakwa iyeza. Oku kulandelwa yimvakalelo yobushushu. Abanye abantu banentloko ebuhlungu, isicaphucaphu, kunye nemvakalelo yokuba iintliziyo zabo ziyabaleka.

Ukuba unikwa iyeza lokwenza intliziyo yakho ibethe ngamandla kwaye ikhawuleze (dobutamine), unokuba nentloko ebuhlungu, isicaphucaphu, okanye intliziyo yakho ingangxama ngokukhawuleza nangakumbi.

Rhoqo, ngexesha lovavanyo abantu banamava:

• Ukungonwabi kwesifuba
• Ukuba nesiyezi
• Iipalpitations
• Ukuqhawukelwa ngumphefumlo

Ukuba ezinye zezi mpawu zenzeka ngexesha lovavanyo lwakho, xelela umntu owenza uvavanyo ngoko nangoko.

Uvavanyo lwenziwe ukubona ukuba izihlunu zentliziyo yakho zifumana ukuhamba kwegazi okwaneleyo kunye neoksijini xa isebenza nzima (iphantsi koxinzelelo).

Umboneleli wakho unoku-odola olu vavanyo ukuze ufumane:

• Lisebenza kakuhle kangakanani unyango (amayeza, i-angioplasty, okanye uqhaqho lwentliziyo) olusebenzayo.
• Ukuba usemngciphekweni omkhulu wesifo sentliziyo okanye iingxaki.
• Ukuba ucwangcisa ukuqala inkqubo yovavanyo okanye utyando.
• Unobangela wentlungu entsha yesifuba okanye ukubola kwe-angina.
• Yintoni onokuyilindela emva kokuba uhlaselwe sisifo sentliziyo.

Iziphumo zovavanyo lwenyukliya zinokunceda:

• Qinisekisa ukuba intliziyo yakho impompoza njani
• Chonga unyango olufanelekileyo lwesifo sentliziyo
• Ukuchonga isifo semithambo
• Khangela ukuba intliziyo yakho inkulu kakhulu

Uvavanyo oluqhelekileyo luhlala luthetha ukuba ubukwazi ukuzilolonga ixesha elide okanye ixesha elide kunelabantu bakho abakwiminyaka yakho kunye nesini. Awunazo iimpawu okanye utshintsho kwixinzelelo lwegazi, i-ECG yakho okanye imifanekiso yentliziyo yakho ebangele inkxalabo.

Iziphumo eziqhelekileyo zithetha ukuhamba kwegazi kwimithambo yegazi eqhelekileyo.

Intsingiselo yeziphumo zakho zovavanyo ixhomekeke kwisizathu sovavanyo, ubudala bakho, kunye nembali yakho yentliziyo kunye nezinye iingxaki zonyango.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Ukuhamba kwegazi kuncitshisiwe kwinxalenye yentliziyo. Isizathu esona sizathu kukuba ukunciphisa okanye ukuvalelwa kweminye imithambo enika intliziyo yakho izihlunu.
• Ukurhawuzelela kwemisipha yentliziyo ngenxa yokuhlaselwa sisifo sentliziyo esidlulileyo.

Emva kovavanyo onokulufuna:

• I-Angioplasty kunye nokubekwa kwesitent
• Utshintsho kumayeza entliziyo yakho
• I-Coronary angiography
• Utyando lwentliziyo ngokudlula

Iingxaki zinqabile, kodwa zinokubandakanya:

• Arrhythmias
• Ukonyusa iintlungu ze-angina ngexesha lovavanyo
• Iingxaki zokuphefumla okanye iimpendulo ezinje ngesifuba
• Ukuguquka okugqithisileyo koxinzelelo lwegazi
• Irhashalala

Umboneleli wakho uya kuchaza umngcipheko ngaphambi kovavanyo.

Ngamanye amaxesha, amanye amalungu kunye nolwakhiwo kunokubangela iziphumo ezibubuxoki. Nangona kunjalo, amanyathelo akhethekileyo anokuthathwa ukunqanda le ngxaki.

Unokufuna iimvavanyo ezongezelelweyo, ezinje nge-catheterization yentliziyo, ngokuxhomekeke kwiziphumo zakho zovavanyo.
