Sick sinus syndrome inowanikwa apo node ye sinus inova nehutano hwakakwana kukonzera bradycardia (inononoka kutara) iyo inobudisa zviratidzo. Vanhu vane chirwere chinorwara sinus vanoda kurapwa neine pacemaker yekusingaperi kuti abvise zviratidzo zvavo.
Mukuwedzera kune chiratidzo chinonzi bradycardia, chirwere chinorwara sinus chinowanzoperekedzeka nezvikamu zvehutachiona hwehutachiona , izvo zvingada kuwedzera kumwe kurapwa.
Kurwara sinus syndrome chirwere chevanhu vakwegura, uye chinowanzoonekwa kuvanhu vanopfuura makore makumi manomwe.
Chii Chinokonzera Kurwara Sineus Syndrome?
Chikonzero chinowanzovhiringidza chechirwere sinus syndrome inobata frosis ane makore-refu inokanganisa node ye sinus (chimiro chiduku muatorium chaiyo inoita kuti mwoyo wekutsvaga kwemagetsi). "Fibrosis" zvinoreva kuti zvisikwa zvakasununguka zvinotsiviwa nechimiro chekuvhara mavara. Apo fibrosis inobata node ye sinus, bradycardia inogona kuguma. Uye apo bradycardia inokonzerwa nechinetso neyo node ye sinus, inonzi "sinus bradycardia."
Izvozvowo, fibroidis yakabatana nezera inobata node ye sinus inogonawo kukanganisa musimba wepanyika pachayo. Izvi zvinowanzoitwa atrial fibrosis zvinotungamirira kuhutano hwehutachiona hunowanzosangana nechirwere chinokonzera chirwere.
Uyezve, iyi fibrosis inogonawo kukanganisa AV node . Kana zvikadaro, sinus bradycardia inogona kuendeswa nezvikamu zve mwoyo block .
Saka muchirwere sinus syndrome pane zvingangova nezvikonzero zviviri zve bradycardia - sinus bradycardia, uye moyo block.
Mune zvimwe zviitiko zvimwe zvirwere zvinogona kuchinja node ye sinus, inobudisa sinus bradycardia. Mamiriro aya anosanganisira:
- amyloidosis
- sarcoidosis
- Chagas chirwere
- hypothyroidism
- dambudziko remwoyo
Zvisinei, fibrosis inobatanidza nekukwegura ndiyo inonyanya kukonzera chikonzero chechirwere sinus syndrome.
Ndezvipi Zviratidzo Zvinosanganiswa Nevanorwara Sinus Syndrome?
Zviratidzo zvinowanzozivikanwa kazhinji zvinokonzerwa nekutapudza kwemwoyo, uye zvinosanganisira:
- easy fatiguability
- kuchena kwemusoro
- syncope
- dyspnea
- kuvhiringidzika
Mune vamwe vanhu vane chirwere chinorwara sinus, zviratidzo izvi zvichaitika apo pavanoedza kuzviedza, uye vachazonzwa zvakanaka zvakakwana pavanenge vachizorora. Muzviitiko izvi dambudziko guru nderekushaya kukwanisa kuwedzera mutengo wemwoyo zvakakodzera panguva yebasa, chiitiko chinonzi " chronotropic kusakwanisa ."
Sick Sinus Syndrome uye Atrial Fibrillation
Vanhu vane chirwere chinonzi sinus node chirwere uye vane zvikamu zvehutachiona hwehutachiona huchawanzoona zviratidzo zvinokonzerwa ne sinus bradycardia, uyezve zvinogona kuva nezviratidzo zve tachycardia (kukurumidza kwemoyo wemwoyo), kunyanya kupora . Vanhu vane zvikamu zvevari zviviri zvinononoka uye zvinokurumidza mwoyo mazana zvinonzi vane bradycardia-tachycardia syndrome, kana " shumba-tachy syndrome ."
Chiratidzo chinotambudza zvikuru chakabatanidzwa nehwesimba-chinetso chirwere is syncope. Kurasikirwa kwekuziva kunowanzoitika pakarepo mushure mekunge chiitiko chetrial fibrillation chichiguma zvachose, zvichiita kuti pause kwenguva refu mumoyo wekura.
Izvi zvinogara kwenguva refu zvichiitika nekuti, kana node ye sinus isati yava "kurwara," chimwe chikamu chekushandiswa kwefridhi yefridhi inotowedzera kunyanya kubvisa basa rayo.
Saka, apo inyanzvi inouraya inouraya pakarepo inomira, node ye sinus inogona kutora masekondi akawanda kuti "amuke" uye atanga kuumba mafungiro emagetsi zvakare. Munguva iyi nguva, pangasava nekurova kwepamoyo zvachose kwemasvondo gumi kana kupfuura - zvichienda kumusoro wakareba, kana kuti syncope.
Inorwara Sei Sinus Syndrome Inowanikwa?
Kuongorora chirwere chinokonzera chirwere hakuwanzooma. Izvozvo zvinowanzoonekwa zvakajeka apo munhu anonyunyutira zviratidzo zvinowanzoonekwa kuti ane sinasi yakakura bradycardia pane electrocardiogram yavo (ECG) . Izvo "shungu-tachy" dzakasiyana-siyana dzechirwere sinus syndrome inowanikwa apo murwere ane chirwere chinonzi sinus node chinowanikwawo kuti ane zvikamu zvehutachiona hwehutachiona.
Nemhaka yekuti fibrosis inokonzera sinus node zvirwere dzimwe nguva inokanganisa chirwere cheAV, vanhu vane chirwere chekushinga-chema chinogonawo kuva nechikamu chemwoyo chinokonzera, uye naizvozvo, inononoka mwoyo yezinga pavanenge vari muutapi friday. Saka, chero nguva munhu ane chirwere chinonzi atrial fibrillation chinowanikwa kuti chinononoka pamwoyo (pasina kushandiswa kwemishonga inotadzisa kuchema kwomwoyo), iyo inofanira kupa chiremba chizivo chakasimba chinorwara sinus syndrome chinogona kunge chiripo zvakare.
Vanachiremba vanogona kuita kuti kuongororwa kwechironotropic kusakwanisa kuburikidza nekucherechedza mwoyo wevarwere muhutano panguva yekurovedza muviri - somuenzaniso, panguva yekuedzwa kwepfungwa . Nemhaka yekuti chronotropic kusagutsikana ndeyezvakajairika kune vakwegura uye ine nyore kurapwa (nezinga-inogadzirisa pacemaker), zvinokosha kune vakwegura vari kutambura nekuneta kana kuenzanisa kushanda kuti vaone kuti vanachiremba vanoita kuongorora kwakakodzera.
Inorwara Sei Sinus Matambudziko Anoitwa?
Vanenge vanhu vose vane chirwere sinus syndrome vanofanira kurapwa neine pacemaker yekusingaperi.
A pacemaker inonyanya kukosha kune vanhu vane maitiro e brady-tachy echirwere sinus syndrome, nokuda kwezvikonzero zviviri. Kutanga, vanhu ava vane ngozi yakakura yekuwana syncope (kubva kune iyo nguva refu inopera apo inouraya fyria inopera). Uye chechipiri, mishonga yakawanda inowanzoshandiswa pakurapa fyria-fracture - beta blockers , calcium channel blockers , uye antiarrhythmic zvinodhaka -zvinogona kuita chirwere chechirwere chechivi chinowedzera. Kushandisa pacemaker kunodzivirira syncope, uye kunobvumira chiremba kuti aite chirwere chepriyri yakawanda zvakachengeteka.
Shoko Rinobva
Muchirwere sinus syndrome, chirwere chemuviri we sinus chinokonzera bradycardia yakakwana kutungamirira kune zviratidzo - kazhinji, nyore nyore kuneta kana kuchena. Izvi zvinogonawo kufambidzana ne-atrial fibrillation iyo, pamwe chete nesinus node chirwere, inoita zvikamu zve syncope zvichida. Sick sinus syndrome inobatwa neine pacemaker inogara nokusingaperi.
