Ingabe izimpawu zikagesi zenhliziyo yakho azisebenzi kahle? Ake sixoxe nge-Trifascicular Block!

Wake wazibuza ukuthi inhliziyo yakho isebenza kahle kangakanani? Ifana nohlelo oluncane lukagesi, oluthumela izimpawu zikagesi ezingxenyeni ezahlukene zenhliziyo ukuze iqhubeke ishaya kahle. Kodwa ngezinye izikhathi, kungaba nokuphazamiseka okuncane ezindleleni zalezi zimpawu zikagesi. Yilapho-ke sikhuluma khona nge-"Heart Block." Namuhla sizokhuluma ngohlobo oluthile lwe-heart block, olubizwa ngokuthi i-trifascicular block.

Ziyini lezi zi-fascicle enhliziyweni? Zikuphi?

Kulungile, manje ake sibheke ukuthi ziyini lezi "fascicles". Kalula nje, lezi yizinqwaba ezikhethekile zemisipha ethwala imiyalezo kagesi ngaphakathi kwenhliziyo. Lezi zibizwa nangokuthi "amagatsha enqwaba." Lezi zitholakala emakamelweni amabili aphansi enhliziyo, "ama-ventricles." Lezi zi-fascicle yizo ezithumela izimpawu zikagesi ngokushesha okukhulu, okwenza amakamelo enhliziyo anciphe kahle futhi ampompe igazi.

Njengoba wazi, inhliziyo yethu iyisitho esiyinhloko sohlelo lokujikeleza kwegazi. Inamakamelo amane amakhulu:

• I-Atria: Amakamelo amabili aphezulu.
• Ama-Ventricle: Amakamelo amabili aphansi. Ibhlogo lama-trifascicular lithinta la makamelo amabili aphansi.

Manje ake sibheke ama-fascicle kula makamelo amabili aphansi:

• I-Ventricle Yangakwesokudla: Lena yigumbi elingezansi ohlangothini lwesokudla lwenhliziyo. Ukusuka lapha, igazi lithunyelwa emaphashini nge-Pulmonary Artery ukuze lithole umoya-mpilo. I-ventricle yangakwesokudla ine-fascicle eyodwa kuphela. Ibizwa ngokuthi i-Right Bundle Branch .
• I-Left Ventricle: Leli yigumbi elingezansi ohlangothini lwesobunxele lwenhliziyo. Lipompa igazi elinomoya-mpilo nge-aorta liye kuwo wonke umzimba. I-ventricle yesobunxele yigumbi lokupompa elikhulu nelinamandla kakhulu enhliziyweni. Linama-fascicle amabili, i-Left Anterior Fascicle kanye ne-Left Posterior Fascicle . Ndawonye, ​​lawa amabili akha i-Left Bundle Branch . La ma-fascicle ahlukana abe yizigidi zemicu emincane ebizwa ngokuthi ama-Purkinje Fibers.

Cabanga ngale ndlela, la ma-fascicle afana nezintambo zikagesi endlini. Uma uvula iswishi (okungukuthi, lapho isignali ifika enhliziyweni), ugesi ugeleza ngalezi zintambo bese uvula isibani (okungukuthi, imisipha yenhliziyo iyafinyela). Ngakho-ke kwenzekani uma kukhona ukuphazamiseka ndawana thize kulezi zintambo? Nokho, yilokho okwenzekayo ekuvinjweni kwenhliziyo.

Ama-Heart Blocks ahlukaniswa kanjani?

Odokotela bahlukanisa la ma-heart block, noma "ama-AV blocks," ngezinhlobo ezintathu eziyinhloko ngokusekelwe ebunzimeni bawo:

1. I-First-degree Block: Lokhu ukubambezeleka okuncane kwezimpawu zikagesi ezivela ku-atria kuya kuma-ventricle. Lokhu "Kuyi-"I-Incomplete Blockage""Ngakho-ke, isikhathi esiningi, azikho izimpawu futhi akukho ukwelashwa okudingekayo.

2. I-Block Yezinga Lesibili: Kulesi simo, ezinye izimpawu zikagesi ziya emaseli, kodwa ezinye aziyi. Lokhu futhi kuyi-block engaphelele. Lokhu kungabangela ukuthi izinga lokushaya kwenhliziyo lehle, okubizwa ngokuthi "i-bradycardia." Noma izinga lokushaya kwenhliziyo lingahluka, okubizwa ngokuthi "i-arrhythmia." Uma leli blok yezinga lesibili liqhubekela ezingeni lesithathu, kungadingeka ukwelashwa.

3. Ukuvinjwa kwe-Third-degree: Lokhu kuvinjwa okuphelele . Azikho izimpawu zikagesi ezithunyelwa kusuka ku-atria kuya kuma-ventricle. Isigqi senhliziyo silawulwa yi-AV node, i-bundle ye-His, noma ama-ventricle ngokwawo. Lokhu kubangela ukuthi izinga lokushaya kwenhliziyo lehle kakhulu. Lokhu kungaba yingozi empilweni, ngakho-ke ukwelashwa kuyadingeka ngokushesha.

Ngakho-ke iyini ngempela i-Trifascicular Block?

Igama elithi "tri" lisho okuthathu. Ngakho-ke, ku-trifascicular block, kukhona ukuvinjelwa ezindaweni ezintathu ohlelweni lokuhambisa inhliziyo, ngaphansi kwe-"AV Node".

Kalula nje, ibhlokhi le-trifascicular liyinkinga ngezibonakaliso zikagesi kokubili egatsheni le-bundle yesokudla kanye nasegatsheni le-bundle yesokudla (okungukuthi, kokubili i-fascicle yesokudla yangaphambili kanye neyesobunxele). Lokhu kubhekwa futhi njengebhlokhi yenhliziyo ephelele . ( Uma kukhona ukuvaleka kwelinye kuphela legatsha le-bundle yesokudla kanye ne-fascicle yesokudla, kubizwa ngokuthi "ibhlokhi le-bifascicular.")

Lokho kusho ukuthi, umuntu one-trifascicular block unazo zombili lezi zimo:

• Ibhulokhi Legatsha Le-Bundle Lesokudla: Kulokhu, isignali kagesi esuka ku-fascicle yesokudla iye egatsheni le-bundle lesobunxele ihamba kancane.
• Ibhulokhi Legatsha Le-Left Bundle: Yilapho isignali kagesi ihamba kancane kakhulu nge-ventricle yesobunxele. Kubhulokhi ye-trifascicular, ukuvaleka kuthinta kokubili i-fascicles yesobunxele yangaphambili kanye neyesobunxele ngemuva.

Cabanga ngalokho okwenzekayo ezimotweni lapho imigwaqo emikhulu emithathu ivalwa ngesikhathi esisodwa. Kwenzeka into efanayo nasemilayezweni esenhliziyweni.

Zivame kangakanani lezi zithiyo zenhliziyo?

Ochwepheshe bathi cishe umuntu oyedwa kwabayi-10 abaneminyaka engaphezu kuka-70 ubudala onomlando wesifo senhliziyo uzoba nokuphazamiseka kwenhliziyo okubangelwa izinga lesithathu ngesikhathi esithile empilweni yakhe.

Yiziphi izimbangela zokuvinjelwa kwe-trifascicular?

Ingozi yokuthola noma yiluphi uhlobo lokuvinjwa kwenhliziyo iyanda njengoba ukhula. Ngezinye izikhathi lokhu kuvinjwa kungenzeka ngaphandle kwesizathu esicacile. Kungabangelwa nesifo senhliziyo esizalwa naso.

Kodwa-ke, ngokuvamile, ukuvinjelwa kwe-trifascicular kubangelwa ukulimala kwenhliziyo. Lo monakalo ungabangelwa izinto ezifana nalezi:

• Isifo Semithambo Yenhliziyo
• Inhliziyo ekhulisiwe (i-Hypertrophic Cardiomyopathy)
• Ukuhlaselwa Yinhliziyo
• Ezinye Izifo Zenhliziyo
• Isifo Se-Valve Yenhliziyo
• Ukwanda kwamazinga e-potassium egazini (i-Hyperkalemia)
• Ukuhlinzwa Kwenhliziyo Okungangeni Kakhulu Noma Ukuhlinzwa Kwenhliziyo Evulekile
• Ukusebenza ngokweqile kwe-Vagus Nerve
• Umkhuhlane We-Rheumatic
• I-Sarcoidosis (isifo lapho amangqamuzana amancane okuvuvukala eqoqana khona ezingxenyeni ezahlukene zomzimba)

Ziyini izimpawu ze-trifascicular block?

Ukuvaleka kwenhliziyo okuthambile (kwezinga lokuqala noma lesibili) akuvamile ukubangela zimpawu. Kodwa-ke, ngokuvaleka kwe-trifascicular, wonke amagatsha amathathu e-bundle ayathinteka, ngakho-ke izimpawu zivame ukwenzeka. Ungase ubhekane nalokhu:

• Ubuhlungu besifuba noma ukuqina (i-Angina)
• Isiyezi Nokuquleka (i-Syncope)
• Ukukhathala
• Ukushaya kwenhliziyo (ukuzwa sengathi inhliziyo yakho iyashaya noma igxumagxuma)
• Isicanucanu
• Ukuphelelwa umoya

Uma unesinye noma ngaphezulu salezi zimpawu, ungazinaki. Kubalulekile ukubona udokotela ukuze uthole iseluleko.

Yiziphi izinkinga ezingaba khona ze-trifascicular block?

Ukuvinjwa kwenhliziyo kwenza kube nzima ngenhliziyo ukupompa igazi emzimbeni wonke. Lokhu kungaholela ezinkingeni ezisongela ukuphila ezifana nalezi:

• Ukushaya kwenhliziyo okungajwayelekile (i-Arrhythmia)
• Isifo senhliziyo
• Ukwehluleka Kwenhliziyo
• Ukufa Kwenhliziyo Okungazelelwe (Ukufa Okubangelwa Ukuhlaselwa Yinhliziyo Okungazelelwe) `(Ukufa Kwenhliziyo Okungazelelwe / Ukuboshwa Kwenhliziyo Okungazelelwe)`

Ngenxa yokuthi lezi yizimo ezibucayi, sithi kubaluleke kakhulu ukufuna ukwelashwa kwezinkinga zenhliziyo ezinjengalezi ngokushesha.

Ihlolwa kanjani i-Trifascicular Block?

Odokotela basebenzisa ukuhlolwa okubizwa ngokuthi "i-electrocardiogram" ukuthola izinguquko ohlelweni lukagesi lwenhliziyo. Lokhu kubizwa nangokuthi i-ECG (E.C.G.) ngamafuphi. Abanye abantu bakubiza nangokuthi i-EKG (E.K.G.).

Lokhu kuhlolwa kwe-ECG kulinganisa umsebenzi kagesi wenhliziyo. Kuphinde kulinganise ukuthi kuthatha isikhathi esingakanani ukuthi izimpawu zikagesi zidlule enhliziyweni. Kukhombisa isikhathi esithatha wonke amakamelo amane enhliziyo ukusebenza.

I-ECG iyisivivinyo esingenabuhlungu, esingangenisi ubuhlungu.Kuthatha cishe imizuzu eyi-15. Kulokhu, "ama-electrode" amancane afana ne-patch anamathiselwe esifubeni sakho, ezingalweni nasemilenzeni. Lawa ma-electrode axhunywe emshinini we-ECG onezintambo. Lo mshini uqopha umsebenzi kagesi wenhliziyo yakho njengegrafu. (I-ECG ayithumeli ugesi emzimbeni wakho, ngakho ungakhathazeki ngalokho.)

Iphathwa kanjani i-trifascicular block?

Abantu abaningi abane-trifascicular block badinga ukuhlinzwa ukuze bafake idivayisi enhliziyweni yabo ukulawula isigqi senhliziyo yabo.

• I-Pacemaker: Lokhu kuthumela izimpawu zikagesi enhliziyweni, okwenza amakamelo enhliziyo ashaye ngesigqi. Kufana nokunikeza inhliziyo "ukusunduza" okuncane ngaphandle.
• Amanye amadivayisi abizwa ngokuthi "Implantable Cardioverter Defibrillators (ICDs)" nawo asebenza njenge-pacemaker. Ngaphezu kwalokho, uma kunengozi yokuma kwenhliziyo ngokuzumayo, lawa ma-ICD aletha ukushaqeka kukagesi enhliziyweni ukuze ishaye ngendlela evamile futhi.

Udokotela uzokuxilonga bese enquma ukuthi hlobo luni lokwelashwa olukufanele.

Ingabe ukuvimba kwe-trifascicular kungavinjelwa?

Nakuba singenakukwazi ukulawula ezinye izimbangela, kunezinto esingazenza ukuze sivikele impilo yenhliziyo yethu. Lokhu kungasiza ekunciphiseni ingozi yezimo ezifana ne-trifascicular block:

• Yidla ukudla okunempilo okunempilo futhi uvivinye umzimba njalo.
• Nciphisa ukusetshenziswa kotshwala.
• Thola izindlela ezinempilo zokuphatha ukucindezeleka .
• Yehlisa isisindo (uma kudingeka) futhi ugcine isisindo esinempilo.
• Lawula izimo ezibangela ukucindezeleka enhliziyweni, njengomfutho wegazi ophakeme, isifo sikashukela kanye ne-cholesterol ephezulu.
• Cela usizo lokuyeka ukubhema nokugwema ukubhema okubhenywa ngomunye umuntu.

Nakuba kungase kube nzima kancane ukufaka lezi zinto endleleni yakho yokuphila ekuqaleni, kuzozuzisa inhliziyo yakho ngokuhamba kwesikhathi.

Sinjani isimo sabantu abane-Trifascicular Heart Blocks?

Ngokwelashwa okufanele, abantu abaningi abane-trifascicular heart block abathuthukeli ekuvinjelweni kwenhliziyo okuphelele. Ingozi iyanda uma i-trifascicular heart block ishiywa ingelashwa. Lokhu kungaholela ekushayweni kwenhliziyo okungajwayelekile (i-arrhythmia), okungenzeka kakhulu ukuthi kubangele ukufa kunokushaywa kwenhliziyo. Ukwelashwa okufanele - ngokuvamile ngedivayisi efana ne-pacemaker - kungasiza ekunciphiseni le ngozi.

Ngingayibona nini udokotela?

Uma unezinye zalezi zimpawu, qiniseka ukuthi ubona udokotela:

• Uma uzizwa ukhathele kakhulu.
• Uma uzizwa sengathi ukushaya kwenhliziyo yakho akujwayelekile.
• Uma unezinhlungu zesifuba ezinzima.
• Uma unenkinga yokuphefumula.
• Uma unezimpawu zokuhlaselwa yinhliziyo (isib. ubuhlungu obukhulu besifuba obuvela engalweni yakho, ubuhlungu bomhlathi, ukujuluka).
• Uma kukhona isicanucanu esingachazeki.

Uma unanoma yikuphi kwalokhu, ungacabangi nje ukuthi, "Lokhu kuyiphutha nje." Funa iseluleko sezokwelapha ngokushesha.

Yini okufanele ngiyibuze udokotela wami?

Uma kutholakala ukuthi une-trifascicular block, ungase ufune ukubuza udokotela wakho imibuzo efana nalokhu:

• Yini eyangenza ngakha leli bhulokhi le-trifascicular?
• Ngingayinciphisa kanjani ingozi yami yokuba nesifo senhliziyo noma esinye isifo senhliziyo?
• Ingabe ngidinga i-pacemaker noma i-ICD?
• Yiziphi izingozi zokufakelwa i-pacemaker noma i-ICD?
• Ingabe kufanele ngikhathazeke ngezimpawu zezinkinga?

Ukubuza le mibuzo kuzokusiza ukuthi uqonde kangcono isimo sakho futhi uhlanganyele ekwelashweni.

Izinto ezibaluleke kakhulu okufanele uzikhumbule (Umyalezo Wokuya Ekhaya)

Ukuvinjwa kwenhliziyo okune-trifascicular kuyisithiyo kuzo zonke izindlela ezintathu eziyinhloko ezithwala izimpawu zikagesi enhliziyweni. Lokhu kuvimbela inhliziyo ukuthi ingafinyeleli futhi ipompe igazi. Ukuvinjwa kwenhliziyo okune-degree yesithathu, noma okuphelele, kungabangela ukushaya kwenhliziyo okungajwayelekile okusongela impilo (ama-arrhythmia) noma ngisho nokufa kwenhliziyo ngokuzumayo.

Abantu abaneminyaka engaphezu kwengu-70 kanye nalabo abanesifo senhliziyo basengozini enkulu. I-ECG ingabona izinkinga ohlelweni lukagesi lwenhliziyo. Udokotela wakho angancoma idivayisi efana ne-pacemaker noma i-ICD. Lawa madivayisi athumela izimpawu zikagesi emakamelweni enhliziyo ukuze aqhubeke eshaya ngesigqi.

Nakekela inhliziyo yakho. Uma uzizwa ungento engavamile, ungayinaki. Ukufuna iseluleko sezokwelapha ngokushesha kungasindisa impilo yakho.

I- trifascicular block, i-heart block, uhlelo lukagesi lwenhliziyo, i-ECG, i-pacemaker, isifo senhliziyo, ukushaya kwenhliziyo
