I-Ultrasound yenhliziyo, ngamanye amazwi, i-echocardiography, eyenziwa ukukhomba okungavamile ekuthuthukiseni isitho kanye nemikhuba yaso. Ubuhlungu be-periodical in the hypochondrium kwesokunxele kudinga ukuvakashelwa ngokushesha ku-cardiologist, ozoqoka ukuhlolwa kwe-ultrasound yenhliziyo futhi ayenze ukucacisa. Inqubo ngokwayo iphephile ngokuphelele.
I-ultrasound yenhliziyo kanjani?
Ukuze inqubo yenhliziyo i-ultrasound, ungabheka ngokuzimela isikhungo sezokwelapha. Ukudlula lesi siqondiso sokuhlonza udokotela akudingeki. Ngaphambi kokuba inqubo iqale, ochwepheshe bazokucela ukuba uguqe esikhwameni bese ulala ngakwesokunxele sakho. Udokotela-ochwepheshe wezokwelapha uzoqala ukusebenzisa ijel ekhethekile yokuziphatha emzimbeni, bese elungisa imininingwane yensizi edingekayo ekunqumeni i-ultrasound yenhliziyo.
Yini i-ultrasound yenhliziyo ebonisa?
I-Ultrasound yenhliziyo ibhekwa njengendlela efundisa kakhulu futhi ephephile yokunquma isimo somzimba omkhulu womuntu. Le nqubo izosiza ukunquma umuntu:
- ubukhulu besitho;
- ukungabikho noma ukutholakala kwezibazi;
- isimo sabo bonke amagagasi;
- ubukhulu bezindonga zangaphandle;
- ukushaqeka umthamo wamakamelo enhliziyo;
- imvamisa yokunciphisa;
- ububanzi be-aorta;
- iphesenti yenqamu ejection.
Ukumiswa kwemiphumela ye-ultrasound yenhliziyo
Emva kokuqedwa kwenhliziyo i-ultrasound, udokotela owaqhuba lo mbuzo uzohlinzeka umbhalo njengesiphetho. Uma kukhona ukuphambuka okujwayelekile, bese emva kwe-ultrasound yenhliziyo, udinga ukuvakashela isazi sokwelashwa.
Njengoba sesiphethe isiphetho socwaningi olwenziwe kungenzeka ukuthi kwenziwe ukucaciswa kwe-ultrasound yenhliziyo evela kumuntu omdala. Kodwa ngaphandle kwemfundo yezokwelapha, isithombe esiphezulu kuphela sesimo segciwane singaqondakala kulolu lwazi. Idatha eboniswe kule protocol kufanele ifaniswe nemingcele evamile ye-ultrasound yenhliziyo:
- ukukhululwa kwe-fractional kuvame ukuphakama kuka-55 kuya ku-60%;
- ukwesaba ivolumu kusuka ku-60 kuya ku-100 ml;
- I-aorta kufanele ibe ngo-2.1 kuya ku-4.1 cm;
- ubukhulu bodonga lwe-diastolic ngokuvamile buphakathi kuka-0.75 no-1.1 cm;
- Izinkomo noma ukuphela usayizi we-systolic kusuka ku-3.1 ukuya ku-4.3 cm;
- ubukhulu be-atrium kwesobunxele buvela ku-1.9 kuya ku-4.0 cm;
- umkhuba we-atrium ofanele phakathi no-2.7 kuya ku-4.5 cm.
Uma kukhona ukuphambuka okuncane emkhakheni wemiphumela esekelwe imiphumela ye-heart ultrasound, kufanele kuqondwe ukuthi imiphumela yocwaningo ingathonywa ubulili, ubudala, impilo ejwayelekile. Ukuxilongwa okuqondile kuyobeka kuphela isazi sezinhliziyo. Ikholi eliphuthumayo kumchwepheshe ozosiza ukuxazulula izinkinga bese uqala, uma kunesidingo, ukwelashwa kwezifo zesimiso senhliziyo .
