Echocardiogram - yomwe imatchedwanso mayesero a echo - ndiyeso yothandiza kwambiri pofufuza momwe thupi likuyendera - makamaka, valves yamtima, ndi ntchito ya minofu ya mtima. Choncho, echocardiogram ndi yofunika kwambiri pofufuza momwe mungapezere matenda a mtima wamagetsi , ndi matenda a minofu a mtima monga kuchepa kwa mtima kapena hypertrophic cardiomyopathy .
Ndiyeso yosasokoneza yomwe ili yotetezeka kwathunthu, ndipo pamene itanthauziridwa ndi akatswiri a cardiologists ophunzitsidwa bwino, ndi yolondola kwambiri.
Kodi Echocardiogram Yachitika Bwanji?
Echocardiogram ndi yesero losavuta kuti lachita. Mudzagona pa tebulo yofufuzira, ndipo wothandizira adzagwira transducer (chipangizo chomwe chikufanana ndi khosi la kompyuta) pachifuwa chanu, pang'onopang'ono mkuwasuntha. (Wopanga ntchitoyo amagwiritsa ntchito gelisi yonga Vaseline ku chifuwa chanu kuti athandizire kutsegula transducer.) Mungafunsidwe kuti mupitirize kumbali yanu pamayesero, kapena mutenge mpweya wanu kwa masekondi angapo. Mayesowa amatenga mphindi 30 mpaka 60 kuti amalize.
Kodi Zojambula Zojambula Zimagwira Ntchito Motani?
Transducer yomwe imayikidwa pachifuwa chanu imatumiza mafunde omveka kumtima. Monga sonar panyanja yam'madzi, mafunde amawombera pamtima, ndipo akabwerera amasonkhanitsidwa ndi transducer. Mafunde akubweranso akugwiritsidwa ntchito ndi makompyuta, ndipo amawonekera pamakina a makompyuta monga chithunzi cha mtima wokonda.
Mwa kusuntha transducer pamwamba pa khoma la chifuwa ndi kuigwedeza pambali yolondola, wothandizira amatha kuwonetsa zofunikira kwambiri zamagulu a mtima.
Kodi Zina Zosintha Zogwiritsidwa Ntchito ndi Echocardiogram Ndi Ziti?
Nthawi zina amagwiritsidwa ntchito pogwiritsa ntchito mayesero opanikizika . Kuyesedwa koyenera kumapangidwanso kupumula, kenaka kubwerezedwa nthawi yochita masewero olimbitsa thupi pofuna kuyang'ana kusintha kwa ntchito ya minofu ya mtima panthawi yolimbikira.
Kuwonongeka kwa minofu kumagwira ntchito nthawi zina kumawonetsa matenda a mitsempha ya mitsempha .
Maikrofoni yapadera (yotchedwa Doppler microphone) ingagwiritsidwe ntchito panthawi ya mayesero kuti ayese kuthamanga kwa magazi m'madera osiyanasiyana mkati mwa mtima. Zomwezi zingakhale zothandiza pofufuza ntchito ya valve yamtima - makamaka ngati mutral wobwezeretsedwa kapena aortic kubwezeretsedwa akukayikira.
Echocardiogram yapamwamba yapamwamba imatha kupanga zithunzi za ziwalo za mtima zimene zimakhala zovuta kuziwona kuchokera muyeso woyenera wa echo, komanso zimapereka njira yobweretsera zojambulajambula pamakono pamene opaleshoni ya mtima ikafika pamene chifuwacho sichipezeka kwa echocardiographer.
Kodi Echocardiogram N'chiyani Chabwino?
Kapepala kakang'ono kameneka kakuwunikira zambiri zokhudza moyo wa munthu.
Ndizothandiza makamaka pozindikira mavuto ndi valves yamtima (monga aortic stenosis kapena mitral valve prolapse ). Zimathandizanso kwambiri pofufuza matenda opatsirana pogonana, monga tetralogy of Fallot.
Mwinanso ntchito yogwiritsidwa ntchito mobwerezabwereza ndiyo kuyesa ntchito yonse ya ventricle ya kumanzere. Makamaka, mayesero a echo ndi mayesero omwe amagwiritsidwa ntchito nthawi zambiri kuti awononge chidutswa chotsalira cha ventricular ejection . Chifukwa chiyeso cha echo ndi chosachiritsika komanso chitetezeka, kachigawo kakang'ono ka ejection kamatha kuyesedwa nthawi zonse ngati kofunikira kuti azindikire momwe matenda osiyanasiyana amathandizira anthu odwala mtima .
Kodi Zina Zingatheke Zotani za Echocardiogram?
Ngakhale kuti echocardiogram imapereka chidziwitso chochuluka ponena za kutuluka kwa mtima wa mtima, sizingathe kufotokozera mitsempha yamakono , kapena mitsempha yamakono. Ngati kuganiza kuti mitsempha yamakono ndi yofunika, catheterization ya mtima imachitika kawirikawiri.
Kwa anthu omwe amasiyana mosiyanasiyana (khoma lachifuwa, makamaka, kapena emphysema), echocardiogram ikhoza kusakhoza kujambula miyambo ya mtima. Ngati kuyesedwa kwa echo kumafunika mwa anthuwa, echocardiogram ya transesophageal ingakhale yothandiza.
