I-echocardiogram - ebizwa nangokuthi uvavanyo lwe-echo - luvavanyo oluncedo kakhulu ekuhloliseni i-anatomy yenhliziyo - ngokukodwa, iintsimbi zentliziyo, kunye nokusebenza kweentliziyo zentliziyo. I-echocardiogram iyanceda gqitha ekuhloliseni ukuba kwenzeka isifo se-valve senhliziyo , nesifo sesifo senhliziyo esifana ne- cardiomyopathy okanye i- hypertrophic cardiomyopathy .
Uvavanyo olungengenangxamnye olukhuselekileyo ngokupheleleyo, kwaye xa luchazwa ngabafundi be-cardiologists abaqeqeshiwe kakuhle, lichanekile.
I-Echocardiogram eyenziwe njani?
I-echocardiogram luvavanyo olulula oluye lwayenza. Uya kulala etafileni yokubhalwa kweemviwo, kwaye uchwephesha uza kubamba i-transducer (isixhobo esifana nesimo sekhompyutheni) kwisifuba sakho, ngokukhawuleza uyisondeza. (I-technician izakusebenzisa i-gelini efana ne-Vaseline kwisifuba sakho ukuze incedise ekulayeleni i-transducer.) Unokucelwa ukuba uqhube kwicala lakho ngexesha lokuvavanya, okanye ubambe ukuphefumula kwakho imizuzwana embalwa. Uvavanyo luvame ukuthatha imizuzu engama-30 ukuya kwangama-60 ukugqiba.
I-Echocardiogram isebenza njani?
I-transducer efakwe kwisifuba sakho ithumela amaza omsindo entliziyweni. Njenge-sonar kwinqwelo-moya, amaza omsindo agxotha kwiintliziyo zentliziyo, kwaye xa zibuya ziqokelelwa ngu-transducer. Amagagasi abuyelayo aqhutywe yikhomputha, kwaye ivela kwikhompyutheni yekhompyutha njengomfanekiso wentliziyo yokubetha.
Ngokuhambisa i-transducer phezu kwodonga lwesifuba nokuyichukumisa ngendlela efanelekileyo, uchwepheshe usenokukwazi ukujonga ngenyameko ubuninzi bezakhiwo zentliziyo ebalulekileyo.
Ziziphi ezinye zeenguqu ezisebenzisiweyo nge-Echocardiogram?
Ngamanye amaxesha ama-Echocardiograms asetyenziswa ngokubambisana novavanyo loxinzelelo . Uvavanyo lwe-echo lwenziwa ngokuphumla, kwaye ke luphindaphindiwe ngexesha lokuzivocavoca ukujonga utshintsho kwimisebenzi yesifo senhliziyo ngexesha lokuzikhandla.
Ukutshatyalaliswa komsebenzi we-muscle ngexesha lokuzivocavoca kunokubonisa ukugula kwesifo se-coronary .
Imakrofoni ekhethekileyo (ebizwa ngokuba yi-Doppler microphone) ingasetyenziswa ngexesha lokuvavanya ukulinganisa ukuhamba kwegazi kwiindawo ezahlukahlukeneyo entliziyweni. Le ngcaciso ingaba luncedo ekuhloleni umsebenzi we-valve senhliziyo-ngakumbi ukuba ukutshintshwa kwe-mitral okanye ukubuyiswa kwe-aortic kukhankanywa.
I- echocardiogram ye-transesophageal inokudala imifanekiso yezakhiwo zengqondo ezinzima ukuzibona kwi-echo test standard, kwaye inika nendlela yokuvelisa imifanekiso ye-echo ngexesha lokuhlinzwa kwentliziyo xa ukufikelela kwisifuba ngokwaso akufumaneki kwi-echocardiographer.
Yintoni i-Echocardiogram efanelekileyo?
I-echocardiogram ibonisa ulwazi olubalulekileyo malunga nesimo senhliziyo.
Kukunceda ngokukhethekileyo ukufumana iingxaki ngeentsimbi zentliziyo (njenge- aortic stenosis okanye i- mitral valve prolapse ). Kukunceda kakhulu ekuhloleni isifo senhliziyo esiswini, njenge-tetralogy of Fallot.
Mhlawumbi ukusetyenziswa ngokuqhelekileyo kwe-echocardiogram kuphonononga umsebenzi wonke we-ventricle ekhohlo. Ngokukodwa, uvavanyo lwe-echo luvavanyo olusetyenziswa rhoqo ukulinganisa iqhekeza le-ventricular ejection . Ngenxa yokuba uvavanyo lwe-echo aluvumelekile kwaye lukhuselekile, iqhekeza le-ejection linokulinganiswa rhoqo njengoko kuyimfuneko ukuvavanya ukuphumelela kwezifo ezahlukeneyo zonyango kwizigulane ezinokukhubazeka kwentliziyo .
Ziziphi ezinye iimida ze-Echocardiogram?
Nangona i-echocardiogram inikezela ngolwazi oluninzi malunga ne-cardiac anatomy, ayikwazi ukufanekisa imiraro ye- coronary , okanye i-coronary blockages. Ukuba ukucinga ngeempawu ze-coronary imfuneko, i- catheterization ye-cardia isenziwa ngokuqhelekileyo.
Kubantu abanokuhlukahluka okwenziwe (udonga olusenyakatho lwebhokisi, umzekelo, okanye i-emphysema), i-echocardiogram ingenakho ukubonisa izakhiwo zomzimba. Ukuba uvavanyo lwe-echo luyadingeka kula bantu, i-echocardiogram ye-transesophageal ingaba luncedo.
