Kuqhelekile ukuba novalo noloyiko xa ugqirha wakho ekuxelela ukuba kufuneka wenze uvavanyo lwentliziyo. Xa sisiva igama elithi "uvavanyo loxinzelelo," uninzi lwethu lucinga ngovavanyo olubandakanya ukubaleka kwi-treadmill. Kodwa ayinguye wonke umntu onokwenza olo hlobo lomthambo. Kwimeko enjalo, uvavanyo olukhethekileyo olubizwa ngokuba luvavanyo loxinzelelo lwe-adenosine lwenziwa ukujonga ukuba intliziyo yakho ifumana igazi kangakanani na. Ngoko ke, masithethe ngayo ngokulula, ngaphandle koloyiko okanye amathandabuzo.
Yintoni kanye kanye le test yoxinzelelo lwe-adenosine?
Ngamafutshane, olu luvavanyo olujonga ukuba intliziyo yakho isebenza kakuhle kangakanani na. Xa sizilolonga, sibaleka, okanye sitsiba, intliziyo yethu ibetha ngokukhawuleza. Oku kubangela ukuba izihlunu zentliziyo zifune igazi elingakumbi. Olu vavanyo lubandakanya ukukunika isixa esincinci seyeza elibizwa ngokuba yi-adenosine, elivula imithambo yegazi entliziyweni yakho ngokungathi ulolonga.
Khawucinge nje, eli yeza lidala imeko apho ubaleka kwi-treadmill. Emva koko, oogqirha banokubona ukuba kukho umahluko phakathi kwendlela intliziyo yakho epompa ngayo igazi xa uphumle kunye nendlela epompa ngayo igazi phantsi kolu hlobo "loxinzelelo."
Kukho izinto eziphambili ezininzi ezijongwa lolu vavanyo:
- Jonga ukuba akukho monakalo ungapheliyo kwimisipha yentliziyo yakho.
- Qinisekisa ukuba intliziyo ifumana igazi neoksijini eyaneleyo .
- Isifo seMithambo yeCoronary (CAD) , esikukuncitshiswa okanye ukuvaleka kwemithambo yegazi ethwala igazi ukuya entliziyweni.
Olu vavanyo lufanele lwenziwe nini?
Olu vavanyo alulungelanga wonke umntu. Ugqirha angalucebisa kumntu onengxaki yokwenza uvavanyo loxinzelelo rhoqo. Nazi ezinye zemizekelo:
- Ukuba awukwazi ukwenza umthambo kwi-treadmill, njengokuhamba okanye ukubaleka (umzekelo, umntu onengxaki yamalungu okanye ubunzima bokuphefumla).
- Ukuba awukwazi ukunyusa izinga lokubetha kwentliziyo yakho liye kwinqanaba olifunayo nangona usenza umthambo.
- Ukuba uthatha amayeza athile, anjenge -beta-blockers .
- Ukuba unesixhobo sokuncedisa ukujikeleza kwegazi esifakwe entliziyweni yakho.
- Ukuba unengxaki ngendlela ezihamba ngayo imiqondiso yombane entliziyweni ebizwa ngokuba yi -left bundle branch block .
Lusebenza njani olu vavanyo?
Nangona oku kungabonakala kuyinkimbinkimbi kancinci, eneneni yinkqubo ecwangcisiweyo kakhulu.
Okokuqala, kufakwa inani elincinci lezinto ezinemisebe (uphawu lwemisebe) okanye ulwelo olukhethekileyo (umahluko) emthanjeni ngelixa uphumle. Emva koko, ikhamera ekhethekileyo (isikena) ithatha imifanekiso yentliziyo yakho. Oku kungabonisa indlela igazi elihamba ngayo entliziyweni yakho ngamaxesha aqhelekileyo okuphumla.
Okulandelayo, iyeza elibizwa ngokuba yi-"Adenosine" linikwa emthanjeni wakho imizuzu embalwa. Xa eli yeza lifakwa emzimbeni wakho, imithambo yegazi esentliziyweni yakho (imithambo ye-coronary) iyavuleka, ngokungathi uqhelisa umzimba. Oku kwandisa isantya igazi elihamba ngaso liye entliziyweni yakho.
Ngelo xesha, izinto ezinemisebe zifakwa emzimbeni kwakhona, kwaye isixhobo sokuskena sithatha imifanekiso yentliziyo. Ngoku oogqirha banokuthelekisa imifanekiso yokuqala nale mifanekiso yesibini.
Ngamafutshane, ukuba igazi lihamba kakuhle kuzo zonke iindawo zentliziyo xa liphumle, kwaye xa "lixinezelekile" ukuhamba kwegazi kwezinye iindawo kuyehla, oko kuthetha ukuba kunokubakho ukuvaleka komthambo wegazi kuloo ndawo.
Iskena esisetyenziswa ukuthatha le mifanekiso ngamanye amaxesha sinokuba siskena se -MRI (Magnetic Resonance Imaging) , okanye iskena esikhethekileyo se-CT (Computed Tomography) .
