Kodi amagwiritsidwa ntchito bwanji?
Electrocardiogram, kapena ECG, ndiyo yesero yowona kwambiri yomwe madokotala amafufuza kuti adziwe mmene mtima ulili. Mgwirizano wa ECG umagwiritsidwa ntchito kwambiri chifukwa ukhoza kusindikiza zochitika zosiyanasiyana za mtima, makina a ECG amapezeka mosavuta m'magulu ambiri azachipatala, ndipo mayeserowa ndi osavuta kuchita, ndi osasamala, ndipo ndi otsika mtengo.
Kodi ECG yachita bwanji?
Munthu yemwe ali ndi ECG yotsogola 12 adzagona pansi pa tebulo yofufuzira ndi chifuwa chake.
(Akazi akhoza kusunga mikono yawo.) Zonse khumi (electrode) (kapena kutsogolera) zimamangirizidwa - imodzi pamanja ndi mwendo, ndi zisanu ndi chimodzi pamphumi. .
Ma electrode amagwiritsidwa ntchito kulembetsa ntchito zamagetsi za mtima. Zizindikiro zamagetsi zimenezi zimatumizidwa ku makina a ECG, kumene akugwiritsidwa ntchito, ndipo amasindikizidwa ngati "ECG kufufuza." Ma electrodes amachotsedwa. Mayeso a ECG amatenga mphindi zisanu kuti achite.
Kodi Kutengera kwa ECG Kumayang'ana Bwanji?
Chithunzi chomwe chili patsamba lino chikuwonetsa ECG yeniyeni, yeniyeni . Zizindikiro za magetsi zopangidwa kuchokera ku ma electrode khumi zakonzedwa kukhala "mawonedwe" 12 a magetsi a mtima - omwe amatchedwa ECG oyendetsa 12. Poganizira zolakwika zonse za ECG, komanso poona zomwe zimachititsa kuti izi zisawonongeke, dokotala akhoza kupeza mfundo zambiri zofunika zokhudza momwe mtima ulili.
Kodi Mungaphunzirepo Chiyani Kuchokera ku ECG?
Kuchokera pa kufufuza kwa ECG, mfundo zotsatirazi zikhoza kudziwika:
- kuyima kwa mtima
- kaya pali maginito a mtima , monga makina osokoneza bongo kapena mapulaneti oopsa .
- ngakhale pali "zoperewera zoperewera" (zosavuta momwe magetsi amafalikira pamtima), monga bundle nthambi .
- kaya pali chizindikiro chilichonse chotsatira kapena choperewera m'mimba
- kaya pali zizindikiro zowonjezereka za matenda a mthupi (CAD)
- kaya minofu ya mtima yayamba kwambiri, monga hypertrophic cardiomyopathy .
- kaya pali zizindikiro zowonongeka kwa magetsi, monga Brugada syndrome .
Zonsezi ndizofunikira kwambiri. Ngakhale kuti ECG ikhoza kufotokoza momveka bwino za matenda ena (monga mtima wamagayimia), nthawi zambiri zimakhala ngati kuyesa kuyesera. Zomwe zimaonedwa ku ECG nthawi zambiri zimafunika kutsatiridwa ndi mayesero omveka bwino kuti atsimikizidwe bwinobwino. Mwachitsanzo, Ngati ECG ikuwonetsa CAD yomwe ingatheke, mayesero okhudza kupanikizika kapena catheterization ya mtima angafunike. Ngati matenda a hypertrophy akuwonekera, nthawi zambiri amafunika kuyang'ana matenda a mtima a valvular (monga aortic stenosis ), kapena zolakwika zina.
Kodi zolepheretsa za ECG ndi ziti?
- Komiti ya ECG imasonyeza kuthamanga kwa mtima ndi maselo pokhapokha masekondi pang'ono akufunika kulembetsa ECG. Ngati magulu a arrhythmia akukayikira, kuyang'aniridwa ndi ambulatory kungafunike.
- Komiti ya ECG ikhoza kukhala yachibadwa kapena yachibadwa kwa odwala omwe alibe chidziwitso cha CAD kapena mitundu ina ya matenda a mtima (zotsatira zoipa zabodza).
- Ambiri "osayenerera" omwe amawoneka pa ECG sakukhala ndi chithandizo chamankhwala pokhapokha kufufuza koyenera kumachitika (zotsatira zabwino zabodza).
Ndi liti pamene muyenera kukhala ndi ECG?
Ndizomveka kuti dokotala wanu apange ECG nthawi yoyamba yomwe akukuonani, monga phunziro loyambirira. Mayesowa akhoza kuyerekezedwa ndi mayesero amtsogolo kuti awone ngati kusintha kulikonse kwakhalako.
Ndizomveka kuchita ECG monga gawo la kafukufuku wamankhwala chaka ndi chaka ngati muli ndi matenda a mtima m'mbuyomu, kapena ngati muli ndi zifukwa zoopsa za matenda a mtima . Komabe, ngati muli ndi thanzi labwino ndipo mulibe zifukwa zazikulu zoopsa, akatswiri ambiri sapereka "zachizoloŵezi" za ECG chaka chilichonse.
