I-Sinus nodal reentrant tachycardia (ebizwa ngokuba yi-SNRT) yenye ye-arrhythmias ekwahlula njenge -tachycardia esezantsi (SVT) , ezihamba ngokukhawuleza zentliziyo ezivela kwi-atria yentliziyo. I-Sinus nodal reentrant reachant tachycardia yindlela ehlukumezayo ye-SVT.
Sibanzi
I-Sinus nodal reentrant tachycardia yinto yokubuyisela i-tachycardia . Njengokuba kunjalo njalo nge-tachycardias, i-sinus nodal reentrant reachrant tachycardia iyenzeka kuba kukho uxhumano olongezelelweyo lombane ngaphakathi kwentliziyo, ekhoyo ukusuka ekuzalweni.
Kwi-sinus nodal reentrant tachycardia, uxhumano olongezelelweyo - kwaye ngokuqinisekileyo yonke isiphaluka esele ivelisa i-arrhythmia-iphakathi kwesodi encinane yesono .
Iimpawu
Iimpawu ze-SNRT zifana neempawu eziqhelekileyo ezibonwayo naluphi uhlobo lwe-SVT. Uphawu olubalaseleyo luyinto yokuphalaza , nangona abanye abantu abanalesi sigqeba baya kubakho "uhlobo olunobunzima" lwezondlo .
Njengoko zininzi ze-SVTs, iimpawu zivame ukuqala ngokukhawuleza kwaye ngaphandle kwesilumkiso esithile. Ziye zanyamalala ngokukhawuleza - ngokuqhelekileyo emva kwemizuzu embalwa kwiiyure eziliqela.
I-node ye-sinus ixhaswe ngokucebisa nge- vagus nererve , ngoko ke abantu abane-sinus nodal reentrant tachycardia banokuthi bayeke iziqephu zabo ngokuthatha amanyathelo okwandisa ithoni ye-vagus nerve, njengokwenza i- Valsalva , okanye ukuxubha ubuso babo emanzini emvula imizuzwana embalwa.
Ukwahlukana kwiSinus Tachycardia engafanelekanga
Isinus tachycardia (IST) engafanelekanga ifana ne-sinus nodal reentrant tachycardia kuba zombini kwezi zi-arrhythmias zivela kwi-node yesusus.
Nangona kunjalo, iimpawu zabo zihluke kakhulu. I-Sinus nodal reentrant tachycardia yinto ephindaphindiweyo ye-tachycardia, ngoko iqala kwaye iyeke ngokukhawuleza, njengokutshintshela nokucima umbane; kwaye xa isigulane singenaso isiganeko sangempela se-tachycardia, isantya senhliziyo yakhe kunye nesandi sesantya sihlala siqhelekileyo.
Ngokwahlukileyo, i-IST yi- tachycardia ngokuzenzekelayo . Ngenxa yoko, aqala kwaye ayeke ngokukhawuleza kodwa kunoko, ngokukhawuleza ngokukhawuleza kukhawuleza kwaye kwancipha kancane kancane. Kananjalo, izinga lentliziyo kubantu abaninzi abane-IST kaninzi alunakunyani "ngokuqhelekileyo." Endaweni yoko, isantya senhliziyo esoloko isoloko ihlala iphakanyisiwe, nangona ingavelanga iimpawu.
Unyango
Ukuba iziqulatho ze-tachycardia ziqhelekanga, kwaye ingakumbi ukuba iziqulatho zinokumiswa ngokukhawuleza ngokukwandisa i-vagal tone, abantu abane-tachycardia e-sinus nodal ingenakufuna nayiphi na inyango yoncedo-ngaphandle kokufunda indlela yokuqonda ukuba i-arrhythmia eyenzekayo, kwaye njani ukuwuyeka.
Ukuba kukho unyango olongezelelweyo olufunekayo - mhlawumbi ngenxa yeepasodes okanye ubunzima ekupheliseni iziqwenga - unyango lweyeza kufuneka lusebenze. Ukuthatha i- beta blocker okanye i- block calcium block blockers kuya kunciphisa kakhulu ubude beepisodes, kunye / okanye ukwenza kube lula ukuyeka.
Ukuba i-sinus nodal reentrant i-tachycardia ingxaki kwaye ingaphenduli kwiyeza elincinci elingaphelanga, unyango lwe- ablation luvame ukuphumelela ekugqibeleni i-arrhythmia ngokupheleleyo.
Nangona kunjalo, kunzima ukususa umbane wongeziweyo kwi-node ye sinus ngaphandle kokulimaza intsalela ye-sinus node.
Ngoko inkqubo yokuphulukisa inomngcipheko ophezulu wokuvelisa i- sinus bradycardia ebalulekileyo, ukwenzela ukuba i- pacemaker engapheliyo iyadingeka.
Ngaloo ndlela, ukuzama ukufumana unyango olungapheliyo kufuneka luhlale lwenziwa ngaphambi kokuqwalasela unyango lwe-inflation ye-sinus nodal reentrant tachycardia.
