Holter monitor

Mumankhwala,aHolter monitorndi mtundu wa ambulatoryelectrocardiographychipangizo, chipangizo chonyamula chakuyang'anira mtima(ndikuyang'anirachantchito yamagetsi yapamtima dongosolo) kwa maola osachepera 24 mpaka 48 (nthawi zambiri kwa milungu iwiri panthawi).

Kugwiritsa ntchito kwambiri kwa Holter ndikuwunikaECG mtimantchito (electrocardiographykapena ECG).Kutalika kwake kojambulira nthawi zina kumakhala kothandiza pakuwonera apo ndi apomtima arrhythmiaszomwe zingakhale zovuta kuzizindikira pakanthawi kochepa.Kwa odwala omwe ali ndi zizindikiro zosakhalitsa, apolojekiti yamtimaomwe amatha kuvala kwa mwezi umodzi kapena kuposerapo atha kugwiritsidwa ntchito.^[1]

Akagwiritsidwa ntchito pophunzira za mtima, mofanana ndi electrocardiography yokhazikika, Holter monitor imalemba zizindikiro zamagetsi kuchokera pamtima kudzera m'magulu angapo.ma elekitirodiwolumikizidwa pachifuwa.Ma elekitirodi amayikidwa pamwamba pa mafupa kuti achepetse zinthu zopangidwa kuchokera ku minofu.Chiwerengero ndi malo a maelekitirodi zimasiyanasiyana malinga ndi chitsanzo, koma owunikira ambiri a Holter amagwiritsa ntchito pakati pa atatu ndi asanu ndi atatu.Ma elekitirodi amenewa amalumikizidwa ku kachidutswa kakang’ono kamene kamamangiriridwa pa lamba wa wodwalayo kapena kulengedwa m’khosi, kusunga chipika cha mphamvu ya magetsi ya mtima panthaŵi yonse yojambulira.Dongosolo lotsogola la 12 la Holter limapezekanso molondolaECGzidziwitso zazizindikiro zimafunikira kuti muwunikenso mtundu weniweni komanso chiyambi cha chizindikiro cha rhythm.

Chojambulira

Kukula kwa chojambulira kumasiyana malinga ndi wopanga chipangizocho.Miyezo yapakati ya oyang'anira a Holter masiku ano ndi pafupifupi 110x70x30 mm koma ena ndi 61x46x20 mm okha ndikulemera 99 g.^[6]Zida zambiri zimagwira ntchito ndi ziwiriAA mabatire.Ngati mabatire atha, ma Holters ena amalola kuti alowe m'malo ngakhale pakuwunika.

Ambiri a Holters amayang'anira ECG kudzera munjira ziwiri kapena zitatu zokha (Zindikirani: kutengera wopanga, mawerengedwe osiyanasiyana otsogolera ndi njira zotsogola zimagwiritsidwa ntchito).Masiku ano ndikuchepetsa kuchuluka kwa zitsogozo kuti zitsimikizire chitonthozo cha wodwalayo panthawi yojambulira.Ngakhale zojambula ziwiri / zitatu zakhala zikugwiritsidwa ntchito kwa nthawi yaitali m'mbiri yowunikira Holter, monga tafotokozera pamwambapa, 12 channel Holters yawonekera posachedwa.Makinawa amagwiritsa ntchito makina otsogola a Mason-Likar, mwachitsanzo, kupanga chizindikiro mumtundu womwewo wa ECG ndi/kapenakupsinjika maganizokuyeza.Ma Holters awa nthawi zina amatha kupereka chidziwitso chofanana ndi cha aECGkupsinjika maganizo mayeso.Amakhalanso oyenera pofufuza odwala pambuyo pakematenda a myocardial infarction.Zojambulidwa kuchokera kwa oyang'anira otsogolera 12wa ndi otsika kwambiri kuposa omwe amachokera ku ECG yotsogola 12 ndipo nthawi zina awonetsedwa kuti akupereka chiwonetsero chosocheretsa cha gawo la ST, ngakhale zida zina zimalola kukhazikitsa ma frequency a sampuli mpaka 1000 Hz kwa mayeso acholinga chapadera monga kuzindikira "zothekera mochedwa".

Chidziwitso chinanso ndikuphatikizidwa kwa kachipangizo ka triaxial movement, komwe kumalemba zochitika za thupi la wodwalayo, ndikuwunika ndi kukonza mapulogalamu, kumatulutsa magawo atatu osuntha: kugona, kuyimirira, kapena kuyenda.Zida zina zamakono zimakhalanso ndi luso lolemba zolemba za odwala omwe amatha kumvetsera pambuyo pake ndi dokotala.Deta iyi imathandiza katswiri wamtima kudziwa bwino zochitika zokhudzana ndi zochitika za wodwalayo ndi diary.
