Chakavanzika chiri shure kwekurova kwemoyo wako: Ngatidzidzei nezve Cardiac Conduction System.

Wakambozvibvunza here kuti moyo wako unorova sei nguva dzose, nemazvo kudaro? Zvakafanana nemaoko ewachi anorova, pasina dambudziko, zuva nezuva, kwemakore... Izvi hazvisi zvimwe chete. Kune sisitimu yemagetsi inoshamisa kwazvo mukati memoyo yedu. Ndiyo yatinodaidza kuti Cardiac Conduction System. Izvi zvakaita se'system yemagetsi' diki mumoyo pachawo. Ngatitaurei nezvesisitimu iyi inoshamisa nemashoko akareruka nhasi.

Chii chinonzi cardiac conduction system?

Muchidimbu, sisitimu yekufambisa mweya wako ine masero, ma node, uye masaini emagetsi. Zvese izvi zvinoshanda pamwe chete kuti mwoyo wako urambe uchirova. Sezvo imba ichida sisitimu yemagetsi kuti ibatidze mwenje, moyo wako haugone kurarama usina iyo.

Kune mhando mbiri huru dzemasero anodzora kurova kwemoyo wedu:

• Masero anofambisa: Aya ndiwo anotakura masaini emagetsi. Akaita senhume diki.
• Masero emhasuru: Aya ndiwo anodzora kusimba kwemoyo. Kureva kuti, 'mapombi' emoyo.

Masaini aya emagetsi anoudza moyo kuti ropa rinofanira kupombwa riini uye sei mumuviri wese. Funga nezvazvo semuchina unodzora kufamba kweropa, uchichengetedza moyo uchishanda panguva chaiyo.

Sisitimu iyi inoshanda sei?

Sisitimu yemoyo wako inofambisa mweya ndiyo inopa chiratidzo chekutanga kurova kwemoyo. Inoudzawo zvikamu zvakasiyana zvemoyo kuti zvinofanirwa kudzikamisa nguva uye kuti zvinofanirwa kuzorora nguvai. Maitiro aya ekudzikamisa uye kuzorora ndiwo anodzora kufamba kweropa mumoyo nemumuviri wese.

Kazhinji, iyi nzira yemagetsi inochengetedza kurova kwemoyo kwakaringana uye kwakaringana . Inobatsirawo kukurumidzisa kurova kwemoyo wako kana uchida ropa rakawanda neokisijeni (semuenzaniso, paunenge uchirovedza muviri) uye kudzikisa kurova kwemoyo wako paunenge wakazorora.

Chii chinoitika panguva yekurova kwemoyo, nhanho nhanho

Nekurova kwemoyo kwega kwega, zviratidzo zvemagetsi zvinofamba munzira yekufambisa mwoyo. Izvi zvakafanana nemafambiro anoita magetsi kuburikidza newaya dziri mumudziyo wepamba. Zvinotanga nekuburitswa kwechiratidzo chekufadza kubva muchikamu chemwoyo chinonzi sinoatrial (SA) node .

Chiratidzo ichi chekukurudzira chinofamba seizvi:

1. Atria (makamuri epamusoro emoyo): Chiratidzo ichi chinotanga chaenda kuatria. Atria yobva yadzikira.

2. Node yeAtrioventricular (AV): Tevere, chiratidzo chinoenda kunode yeAV. Pano, chiratidzo chinononoka zvishoma. Chikonzero cheizvi ndechekupa ropa rese panguva yeatria kuti riende kumakamuri epasi emoyo.

3. Bundle of His: Mushure meAV node, chiratidzo chinofamba nepabundle iyi yeHis kuenda kuPurkinje fibers.

4. Masero (Ventricles - makamuri epasi emwoyo) achishandisa mafiber ePurkinje:Masero paanozogamuchira chiratidzo ichi, anogumira. Ndipo panoburitswa ropa kubva mumoyo nemumuviri wese.

Kana matanho aya akabatana, kunenge kuri kudhonzana kwetsandanyama yemwoyo kamwe chete. Sisitimu yemagetsi yemoyo wako inotumira zviuru zvezviratidzo izvi pazuva, zvichiita kuti mwoyo wako urambe uchirova usingamire. Hazvishamisi here?

Ndezvipi zvikamu zvikuru zvehurongwa hwekufambisa mwoyo?

Kune masero nemanode akasiyana-siyana ari muhurongwa hwekufambisa kwemoyo wako anodzora kurova kwemoyo wako. Aya ndiwo:

• Node yeSinoatrial (node ​​yeSA)
• Atrioventricular node (AV node)
• Boka reHis (boka reatrioventricular)
• Mashinda ePurkinje

Zvino ngatitarisei chimwe nechimwe chezvikamu izvi zvakadzama.

Sinoatrial node (Sinoatrial - SA node)

Sinoatrial node yako (SA node) ndiyo pacemaker yemoyo. Yakafanana ne'boss' yemoyo. Ndiyo inotuma ma impulses emagetsi anotanga kurova kwemoyo. Dzimwe nguva, kana SA node isingashande zvakanaka, zvikamu zvepasi zve conduction system zvinoshanda semasero anobatsira pacemaker.

Node yeSA iri muchikamu chepamusoro cheatrium yekurudyi yemoyo. Kunyanya, pedyo nepanosvika superior vena cava, tsinga huru inotakura ropa risina oxygen kubva mumuviri wako kuenda kumoyo, inosangana neatrium.

Sisitimu yako yetsinga inotonga kuti node yeSA inotumira zviratidzo zvemagetsi nekukurumidza kana kunonoka kwakadii. Chikamu ichi chesisitimu yetsinga chinoburitsa mahormone anodzora kurova kwemoyo wako zvichienderana nezvauri kuita. Semuenzaniso, kurova kwemoyo wako kunowedzera paunorovedza muviri uye kunoderera paunorara.

Sisitimu yetsinga ye autonomic ine zvikamu zviviri zvikuru:

• Sisitimu yetsinga inonzwira tsitsi: Izvi zvine chekuita ne'kurwisa kana kubhururuka'. Zvinoita kuti node yeSA ishande, zvichiita kuti kurova kwemoyo kuwedzere.
• Parasympathetic nervous system: Izvi zvine chekuita ne'rest and digest response'. Zvinoderedza SA node uye zvinoderedza kurova kwemoyo.

Atrioventricular node (AV node)

Node yako yeatrioventricular (AV node) iri pedyo nepakati pemoyo wako. Inoita izvi nekunonotsa chiratidzo chemagetsi kubva kuSA node kwenguva yakati (chikamu chesekondi) nguva imwe neimwe.

Kunonoka uku kwakakosha zvikuru nekuti kunoita kuti ropa rese riri mumakamuri epamusoro emwoyo (atria) ripinde mumakamuri epasi (tsinga) risati ramira kugwinha.

Atria ndiyo inogamuchira ropa kubva mumuviri yoritumira kumasero.

Boka reHis (boka reatrioventricular)

Boka reHis iboka remafiber (masero etsinga) rinotangira paAV node. Boka iri remafiber rinogamuchira chiratidzo chemagetsi kubva paAV node rochiendesa kuPurkinje fibers.

Bhuru rebvudzi rinofamba nemadziro (septum) rinoparadzanisa ma ventricle ako ekurudyi nekuruboshwe. Bhuru iri rine mapazi maviri makuru:

• Bazi rekuruboshwe: Izvi zvinotumira masaini emagetsi ku ventricle yekuruboshwe kuburikidza nePurkinje fibers.
• Bazi repazasi rekurudyi: Izvi zvinotumira masaini emagetsi ku ventricle yekurudyi kuburikidza nePurkinje fibers.

Mashinda ePurkinje

Mafiber ePurkinje inetwork yemasero etsinga anonyanya kufambisa masaini emagetsi nekukurumidza kuenda kumakamuri ekurudyi nekuruboshwe emwoyo wako. Mafiber ePurkinje ari mumadziro emaventricle ako, chikamu chemukati chenyama chiri mumakamuri emwoyo wako.

Kana tambo dzePurkinje dzichitumira masaini emagetsi kumasero ako, masero anogumira. Ropa rinozoyerera kubva ku right ventricle richipinda mu pulmonary arteries uye kubva ku left ventricle richipinda mu aorta. Mitsipa yemapapu inotakura ropa kuenda kumapapu kuti ritore oxygen. Aorta ndiyo tsinga huru mumuviri wako, uye inotakura ropa kubva pamoyo kuenda kumuviri wako wese.

Zvikamu izvi zvinotaridzika sei?

Izvi zvikamu zvidiki chaizvo. Semuenzaniso, node ye`SA` yakareba mamirimita gumi nemashanu (yakaenzana nepini ye stapler) uye yakafara mamirimita mana. Node ye`AV` yakareba mamirimita mashanu uye yakafara (yakaenzana nemucheto weswitch yemwenje). Boka reHis, matavi ayo, uye machira ePurkinje pamwe chete zvinonzi zvinoita semuti wakasvetukira pasi. Boka reHis nematavi ayo rinotaridzika sehunde yemuti, uye machira ePurkinje anotaridzika sematavi emuti.

Matambudziko api anogona kuitika muhurongwa uhwu?

Matambudziko akasiyana-siyana ehutano anogona kukanganisa mashandiro emagetsi emwoyo wako. Matambudziko nehurongwa hwekufambisa mweya anogona kukonzera matambudziko ekurova kwemoyo .

Matambudziko akajairika ekurova kwemoyo:

Heano mamwe mamiriro ezvinhu akajairika:

• Arrhythmia: Kurova kwemoyo kusina kurongeka. Izvi zvinosanganisira chirwere chinonzi atrial fibrillation (Afib).
• Bundle branch block: Kuvharika kwePurkinje fibers kune rumwe rutivi rwemoyo. Izvi zvinogona kukonzera kusagadzikana kwemoyo.
• Kuvharika kwemoyo: Kutapurirana kwemagetsi pakati peatria nemaventricle emoyo.
• Long QT syndrome (LQTS): Mwoyo unotora nguva yakareba kuti uzvimbambe uye udzokere pakuva wakajairika. Izvi dzimwe nguva zvinogona kukonzera kuvhiringidzika kwepfungwa kana kumira kwemoyo.
• Kurwadziwa kwemoyo nguva isati yakwana: Chirwere chekuti moyo unorova nekukurumidza. Izvi zvinogona kukonzera kurova kwemoyo kana kunzwa sekuti "kurova kwemoyo kwakundikana."
• Kumira kwemoyo: Kumira kwemoyo kamwe kamwe kunokonzerwa nekurova kwemoyo zvisina kurongeka. Izvi zvinogona kuuraya kana zvikarapwa nekukasika. Ichi chirwere chine njodzi zvikuru.

Ndezvipi zviratidzo zvedambudziko?

Kana paine dambudziko nehurongwa hwemoyo wako hwekufambisa mweya, unogona kuona zviratidzo zvakaita seizvi:

• Kuoma kufema
• Kurwadziwa kwechipfuva
• Kurova kwemoyo nekukurumidza kana kusina kurongeka (kurova kwemoyo)
• Dzungu
• Dzungu
• Basa rakaoma

Kana uine zviratidzo zvakadai, zvakakosha zvikuru kutsvaga rubatsiro rwechiremba nekukasika.

Chiremba anogona kuita electrocardiogram (EKG) kuti aongorore rhythm yemwoyo wako. Kana vachida kuramba vachitarisa mashandiro emagetsi emwoyo wako, vanogona kukukumbira kuti upfeke heart monitor kwemazuva mashoma kana mavhiki. Chidzidzo che electrophysiology chinogona kupa ruzivo rwakadzama nezvehurongwa hwekufambisa moyo wako.

Matambudziko ane chekuita nemagetsi emwoyo anogona kurapwa nemishonga uye marapirwo akadai sekuisirwa kwepacemaker .

Ndingachengetedza sei hurongwa hwemoyo wangu hwekufambisa ropa huine hutano?

Hatigoni kuchinja majini anokonzera matambudziko akawanda emwoyo. Zvisinei, unogona kubatsira kuchengetedza moyo wako wese uine hutano nekutevera tsika dzakanaka . Heano mamwe maitiro aunogona kuita:

• Ramba uine huremu hwakanaka hunokunakira.
• Rega kushandisa zvigadzirwa zvefodya uye dzivisa kusvuta fodya kubva kune vamwe vanhu.
• Inwa mushonga wacho sezvawakarairwa nachiremba.
• Deredza kunwa kwako doro kana zvinwiwa zvine caffeine .
• Idya zvekudya zvinovaka muviri zvakaita semichero, miriwo, uye zviyo zvakakwana.
• Iva nemuviri unoshanda kwemaminitsi angangoita 150 pasvondo.
• Dzora kushushikana uchishandisa nzira dzine hutano dzakadai sekutaura kana kufungisisa.

Ungasaziva nezvemagetsi emwoyo wako kusvika wava nedambudziko rekurova kwemoyo wako. Asi zviratidzo izvi ndizvo zvinoita kuti mwoyo wako urove uye ufambise ropa. Kuziva mashandiro anoita system iyi kunogona kukubatsira kuona matambudziko anogona kuitika uye kuwana rubatsiro.

Pfungwa pfupi dzekurangarira

Zvakanaka, ngationgororei zvimwe zvezvinhu zvakakosha zvekurangarira kubva pane zvatataura nezvazvo nhasi.

• Sisitimu yekufambisa mwoyo yemwoyo wako inetwork yemagetsi inodzora kurova kwemoyo wako.
• Inoumbwa nezvikamu zvikuru zvinonzi `SA` node, `AV` node, bundle of His, uye Purkinje fibers .
• Matambudziko nehurongwa uhwu anogona kukonzera kusagadzikana kwemoyo (arrhythmias) .
• Kana ukaona zviratidzo zvakaita sekuoma kufema, kurwadziwa pachipfuva, kana kupera simba, tsvaga rubatsiro rwechiremba nekukasika.
• Nekutevera mararamiro ane hutano (kudya zvakanaka, kurovedza muviri, kurega kusvuta, uye kudzora kushushikana), unogona kuchengetedza hurongwa hwemwoyo nemwoyo wako wese zvine hutano.

Saka, chengetedza moyo wako. Inhengo inoshamisa inoshanda nesimba kwauri!
