Unyango luyakwazi ukuphazamiseka phakathi kweentlobo ezahlukeneyo ze-SVT
I-tachycardia yesigqeba (SVT) yinkalo ye-arrhythmias ye-cardiac ephuthumayo evela kumagumbi aseburhulumenteni entliziyweni. ("I-Supraventricular" ithetha nje "ngaphezu kweefrijiki.")
Kukho iintlobo ezahlukahlukeneyo ze-SVT, kodwa kumntu onabo bonke abane-SVT bavame ukuvakalelwa ngokufanayo. Ngokuqhelekileyo zivelisa iipelpitations, kwaye zihlala zilula, kwaye ngoxa ziphantse zize zisongela ubomi, nayiphi na uhlobo lwe-SVT lunokuba nzima ukunyamezela.
Nangona iimpawu zazo zonke iintlobo ze-SVT zifana, xa kuziwa kunyango kukho ukubaluleka okubalulekileyo. Ngoko xa ugqirha unyanga umntu nge-SVT, kubalulekile ukufumanisa uhlobo luni lwe-SVT. I-SVTs ikwahlula kwiindidi ezibanzi ezibanzi: "ukungena kwakhona" kunye "nokuzenzekelayo" i-SVT.
Ukubuyisela iSVT
Uninzi lwabantu abaye bazalwa yi-SVT bafumana uxhumano olongezelelweyo lombane entliziyweni yabo. Ezi ziqhagamshelwano ezingaphezulu zenza isiphaluka sombane.
Ngaphantsi kweemeko ezithile, iinjongo zombane zentliziyo zinokuthi "zithinteke" ngaphakathi kwesekethe, zijikeleze kwaye zijikeleze ngeenxa zonke. Ngomtya ngamnye, intliziyo entsha iveliswa, ivelisa i- tachycardia . Uhlobo lwe-tachycardia oluveliswe ngolu hlobo oluxhamlayo lubizwa ngokuba yi- reachant tachycardia.
Iintlobo eziqhelekileyo zokufumana ii-SVTs
Amagama anikezelwe kwiindidi ezahlukahlukeneyo ze-SVT zingangokudideka, kodwa isitshixo kukuba amagama abonisa ukuba uxhumano olongezelelweyo lufumaneka entliziyweni.
Iintlobo eziqhelekileyo ze-SVT zidweliswe apha. Cofa kwikhonkco ukuba ufunde malunga neempawu ezithile zohlobo ngalunye:
- I-Atrioventricular reentrant reachrant tachycardia, okanye i-AVNRT , ebangela malunga ne-60% yazo zonke i-SVTs.
- I-Atrioventricular reciprocating tachycardia, okanye i-AVRT , uhlobo lwe-SVT olubandakanya uWolff-Parkinson-White Syndrome (WPW) . I-AVRT ibangela malunga ne-30% yazo zonke i-SVTs.
- I-Sinus nodal reentrant reachrant tachycardia , okanye i-SNRT, ebangela ngaphantsi kwe-5% ye-SVTs.
- I-retraatrial reentrant reachant tachycardia, okanye i-IART, nayo ibangele ngaphantsi kwe-5% ye-SVTs.
Nangona ukhetho lwonyango kuzo zonke iindidi ze-SVT ephinde zibandakanya ziquka zombini iinkqubo zokuxhoma kunye neyeza, unyango "olungcono" luxhomekeka kumgama othile.
Tachycardias ngokuzenzekelayo
Uhlobo olulodwa lwe-SVT alubangelwa ukuxhamla kombane okongezelelweyo entliziyweni. Olu hlobo lwe-SVT lubizwa ngokuba yi-"Automatic SVT."
Ngokuqhelekileyo, isandi senhliziyo silawulwa yimpembelelo yombane eveliswe yi-"pacemaker" iiseli zeentliziyo, ezikwimeko yesono .
Kodwa ngokuzenzekelayo i-SVT, iiseli kwezinye indawo kwindawo ye-atria ziqala ukuvelisa iimpembelelo zabo zombane, ngokukhawuleza kunokuba i-node ye sinus iyenjenjalo, ngaloo ndlela ithatha isigqi sentliziyo kwaye ivelise i-SVT ngokuzenzekelayo.
I-SVTs ezizenzekelayo zincinane kakhulu kuneSVTs ezingenayo. Ngokuqhelekileyo zivela kuphela kubantu abanesifo esibalulekileyo sonyango - ingakumbi isifo esiyingozi se-lung, i- hyperthyroidism engalawulwayo, okanye ezininzi izifo ezinzima ngokwaneleyo ukufuna ukunakekelwa kwezibhedlele.
I-SVTs ngokuzenzekelayo iyanzima ukuphatha ngokuthe ngqo, kuba akukho uxhumano olongezelelweyo lombane olungaqulunqwa, kwaye ekubeni izidakamizwa zange- antiarrhym ehlala zingasebenzi kakuhle ekunqandeni izi arhythmias.
Ngoko unyango lwangempela lwe-SVT yindlela echanekileyo yonyango, oko kukuthi, ukunyanga kwesifo sengonyango. Phantse njalo, xa isigulane ngokuzenzekelayo i-SVT sele ifunyenwe ngokwaneleyo ukuba ikhutshwe kwiyunithi yonyango enzulu, i-arrhythmia iya kubakho.
Uhlobo oluthile olukhethekileyo lwe-SVT oluzenzekelayo alukho ngenxa yokugula kanzima kwaye luhlala luhlala lunzima kwaye lukhuni ukulawula. Le sinus tachycardia engafanelekanga (IST), efanelekileyo ingxoxo yayo .
Qaphela: Nangona i-fibrillation ye-atrial ifom ye-SVT, ithatyathwa njengowesigaba sayo. Funda apha malunga nefayili yefriji .
