Kuvamile ukuzizwa ukhathazekile futhi ukhathazekile kancane lapho udokotela wakho ekutshela ukuthi udinga ukuhlolwa kwenhliziyo. Uma sizwa igama elithi "ukuhlolwa kokucindezeleka," iningi lethu licabanga ngokuhlolwa okuhilela ukugijima ku-treadmill. Kodwa akuwona wonke umuntu ongenza lolo hlobo lokuzivocavoca. Esimweni esinjalo, kwenziwa ukuhlolwa okukhethekile okubizwa ngokuthi ukuhlolwa kokucindezeleka kwe-adenosine ukuze kuhlolwe ukuthi inhliziyo yakho ithola igazi kangakanani. Ngakho-ke, ake sixoxe ngakho ngamazwi alula, ngaphandle kokwesaba noma ukungabaza.
Iyini ngempela le ndlela yokuhlola ukucindezeleka kwe-adenosine?
Kalula nje, lokhu ukuhlolwa okuhlola ukuthi inhliziyo yakho isebenza kahle kangakanani. Uma sizivocavoca, sigijima, noma sigxuma, inhliziyo yethu ishaya ngokushesha. Lokhu kubangela ukuthi imisipha yenhliziyo idinga igazi elengeziwe. Lokhu kuhlolwa kuhilela ukukunikeza inani elincane lomuthi obizwa ngokuthi i-adenosine, ovula imithambo yegazi enhliziyweni yakho njengokungathi uyazivocavoca.
Cabanga nje, lo muthi ngokwenziwa udala isimo lapho ugijima khona ku-treadmill. Khona-ke, odokotela bangabona ukuthi kukhona yini umehluko phakathi kwendlela inhliziyo yakho epompa ngayo igazi uma uphumule nendlela epompa ngayo igazi ngaphansi kwalolu hlobo "lokucindezeleka."
Kunezinto eziningana eziyinhloko ezibhekwa yilolu vivinyo:
- Hlola ukuthi kukhona yini umonakalo ohlala njalo emisipheni yenhliziyo yakho.
- Qiniseka ukuthi inhliziyo ithola igazi nomoya-mpilo owanele .
- Isifo Semithambo Yenhliziyo (CAD) , okuwukuncishiswa noma ukuvaleka kwemithambo yegazi ethwala igazi liye enhliziyweni.
Kufanele kwenziwe nini lokhu kuhlolwa?
Lokhu kuhlolwa akulona okwawo wonke umuntu. Udokotela angase akuncomele umuntu onenkinga yokwenza ukuhlolwa kokucindezeleka okuvamile. Nazi ezinye izibonelo:
- Uma ungakwazi ukuzivocavoca ku-treadmill, njengokuhamba noma ukugijima (isibonelo, umuntu onezinkinga zamalunga noma ubunzima bokuphefumula).
- Uma ungakwazi ukushaya kwenhliziyo yakho kuze kufike ezingeni olifunayo naphezu kokuzivocavoca umzimba.
- Uma uthatha imithi ethile, njenge -beta-blockers .
- Uma une- pacemaker efakwe enhliziyweni yakho.
- Uma unenkinga ngendlela izimpawu zikagesi ezihamba ngayo enhliziyweni ebizwa ngokuthi i-left bundle branch block .
Lolu vivinyo lusebenza kanjani?
Nakuba lokhu kungase kubonakale kuyinkimbinkimbi kancane, empeleni kuyinqubo ehlelekile kakhulu.
Okokuqala, inani elincane lezinto ezinemisebe (uphawu lwemisebe) noma uketshezi olukhethekile (umehluko) lufakwa emthanjeni ngenkathi uphumule. Ngemuva kwalokho, ikhamera ekhethekile (isithwebuli) ithatha izithombe zenhliziyo yakho. Lokhu kungabonisa ukuthi igazi ligeleza kanjani enhliziyweni yakho ngezikhathi zokuphumula ezivamile.
Okulandelayo, umuthi obizwa ngokuthi "i-Adenosine" unikezwa emithanjeni yakho imizuzu embalwa. Uma lo muthi ufakwa emzimbeni wakho, imithambo yegazi enhliziyweni yakho (imithambo ye-coronary) iyavuleka, njengokungathi uvivinya umzimba kanzima. Lokhu kwandisa isivinini igazi eligeleza ngaso enhliziyweni yakho.
Ngaleso sikhathi, izinto ezikhipha imisebe zifakwa emzimbeni futhi, bese isithwebuli sithatha izithombe zenhliziyo. Manje odokotela bangaqhathanisa izithombe zokuqala nalezi zithombe zesibili.
Kalula nje, uma igazi ligeleza kahle kuzo zonke izingxenye zenhliziyo uma liphumule, futhi uma "licindezelekile", ukugeleza kwegazi kwezinye izindawo kwehla, kusho ukuthi kungase kube nokuvaleka komthambo wegazi kuleyo ndawo.
Isithwebuli esisetshenziswa ukuthatha lezi zithombe ngezinye izikhathi singaba isithwebuli se -MRI (Magnetic Resonance Imaging) , noma isithwebuli esikhethekile se-CT (Computed Tomography) .
Kufanele ngilungiselele kanjani ngaphambi kokuhlolwa?
Lena yingxenye ebaluleke kakhulu. Kumelwe ulandele le miyalelo ngqo ukuze imiphumela yokuhlolwa ibe nembambo.
| Okufanele ngikwenze | Incazelo nokubaluleka |
|---|---|
| Tshela udokotela konke. | Qiniseka ukuthi utshela udokotela wakho nganoma yiziphi izimo zezokwelapha onazo (ikakhulukazi i-asthma) kanye nanoma yimiphi imithi oyithathayo (kufaka phakathi amavithamini kanye nemithi yamakhambi). Ezinye izimo zenza lokhu kuhlolwa kungafaneleki ukusetshenziswa. |
| Uma une-asthma | Kungase kudingeke uyeke ukuthatha imithi ye-asthma efana ne-theophylline ezinsukwini ezimbili ngaphambi kokuhlolwa. Khuluma nodokotela wakho ngalokhu. Futhi, qiniseka ukuthi uletha i-asthma inhaler yakho ekuhlolweni. |
| I-caffeine ayivunyelwe! | Lokhu kuyinto ebaluleke kakhulu. Ungadli noma uphuze noma yini equkethe i-caffeine amahora angama-24 ngaphambi kokuhlolwa. Lokhu kungenxa yokuthi i-caffeine iphazamisa ukusebenza komuthi we-adenosine. Izinto okufanele uziyeke:

| Ukubhema | Gwema ukubhema ngokuphelele ngosuku lokuhlolwa. |
| Uhlu lwemithi | Letha uhlu lwazo zonke imithi (kufaka phakathi amavithamini) ovame ukuyithatha. |
| Iseluleko esikhethekile kubantu abanesifo sikashukela | |
| Uma uthatha i-insulin | Udokotela wakho kungadingeka alungise umthamo wakho we-insulin. Ungase utshelwe ukuthi uthathe ingxenye yomthamo wakho wasekuseni bese udla ukudla okulula amahora amane ngaphambi kokuhlolwa. Ungalokothi ushintshe umthamo wakho ngaphandle kokubuza udokotela wakho kuqala. |
| Uma uphuza amaphilisi | Ungase ucelwe ukuthi uyeke ukuthatha amaphilisi akho esifo sikashukela kuze kube yilapho ukuhlolwa sekuphelile. |
| Imitha ye-glucose | Letha i-glucose monitor yakho. Ungahlola amazinga kashukela egazini lakho ngaphambi nangemva kokuhlolwa. Uma uzizwa uphansi, tshela abasebenzi ngokushesha. |
Kwenzekani ngesikhathi sokuhlolwa? Ingabe kufanele ngesabe?
Asikho isizathu sokwesaba. Abasebenzi bezokwelapha bazokunakekela kahle. Nazi ezinye zezinto ezizokwenzeka:
- Bazofaka imigqa emibili ye-IV emthanjeni engalweni yakho. Omunye ukukunikeza umuthi, kanti omunye ukukunikeza izinto ezikhipha imisebe.
- Ama-electrode , ayizitikha ezincane, abekwa esifubeni sakho. Lawa asetshenziselwa ukuqapha njalo ukusebenza kwenhliziyo yakho kusetshenziswa umshini we-EKG (Electrocardiogram) .
- I -blood pressure cuff ibekwa engalweni yakho futhi umfutho wegazi wakho ulinganiswa njalo.
- Uzoyiswa kuskena bese ucelwa ukuthi ulale unganyakazi cishe imizuzu engama-45 .
- Bakutshela ukuthi ubambe umoya wakho imizuzwana embalwa ngenkathi uthatha izithombe.
- Ngaphambi kokuba unikezwe i-adenosine, uzokwaziswa ngemiphumela yayo engase ibe khona.
Yonke inqubo ingathatha cishe amahora amabili, kodwa ukuskena ngokwako kuthatha cishe imizuzu engama-45.
Ingabe kukhona imiphumela emibi kulokhu?
Umuthi we-adenosine uhlala emzimbeni isikhathi esifushane kakhulu. Ngakho-ke noma ngabe kuvela imiphumela emibi, ivame ukuphela ngemizuzwana embalwa ngemva kokuyeka umuthi. Cishe abantu abangu-80% abenza lokhu kuhlolwa bathola imiphumela emibi emincane.
