Ingabe inqubo yenhliziyo i-ultrasound ibalulekile?

Njengoba wonke umuntu esazi kakade isikhathi eside, inhliziyo yomuntu ngokuyinhloko iqukethe amakamelo angu-4: amabili ayo abizwa ngokuthi i-atrium, kanti amanye amabili angama-ventricles. Ama-auricles ahlukanisa ngakwesokunene nangesobunxele enhliziyweni ahlala engxenyeni engaphezulu, futhi ama-ventricle angakwesokunxele nangakwesokudla anesisekelo sayo esingaphansi. Ukubona kahle uma ukugeleza kwegazi phakathi kwalezi zingxenye ze-myocardium kulungile, bonke abantu ngokushesha noma kamuva benza inqubo odokotela abayibiza ngokuthi i-ultrasound yenhliziyo.

I-ultrasound yenhliziyo, noma i-echocardiography yesayensi yindlela yokucwaninga evumela ukukhomba ukutholakala kwezimo ezihlukahlukene zesakhiwo, kanye nezinguquko ezingaziwa ku-myocardium. Ukwengeza, usebenzisa inqubo ye-ultrasound yenhliziyo, ungafunda ngokuvela kwezifo ezihlukahlukene kanye nezindlela ezimbi ekuthuthukiseni izingxenye phakathi kwenhliziyo.

Kumele kuqashelwe ukuthi okwamanje i-echocardiography isetshenziswa kabanzi futhi isetshenziselwa ukuxilongwa kwe-myocardial malformation ezinganeni nakwabesifazane abakhulelwe, kanye nokuthola izifo ezinsikeni zenhliziyo. Ngaphezu kwalokho, ngosizo lwezinyosi zenhliziyo, umuntu angakwazi ngokunembile ngezifo ezisezintanjeni zenhliziyo kanye nokuhluleka kwensimu yenhliziyo.

Ukumisa i-yifi yenhliziyo nenhloso esemqoka yokusebenzisa inqubo.

I-Ultrasound yenhliziyo manje iyindlela efinyeleleka kakhulu futhi elula phakathi kwazo zonke izifundo ze-myocardial, okukuvumela ukuba uhlole ngokushesha futhi ngokunembile zonke izifo ezinsikeni zenhliziyo ngaphambi kokuqala kwezimpawu ezihlukahlukene. Ngosizo lwe-echocardiography, ungabona okudingekayo ukuze kuqalwe isifo esihlobene nesifo somzimba we-coronary, futhi uqinisekise izikhalazo zeziguli ze-dyspnea, ugozi oluqhubekayo, nokubonakaliswa kobuthakathaka nokulahlekelwa yilapho njalo.

Kodwa udokotela ubeka i-echocardiography kuphela lapho kutholakala khona umsindo ongenalutho emotweni ye-myocardium, kanye nalapho kusolwa ukuthi izifo ezivame ukuholela ekunqothulweni kwenhliziyo yonke. Ngaphezu kwalokho, iziguli ezine-high blood pressure kanye nezinguquko ezivamile kudivayisi ye-ECG zitholakala isheke sonyaka se-ultrasound.

Okwamanje, i-yifi yenhliziyo, intengo ephansi, yenziwa ngosizo lwezinsimbi ezikhethekile zanamuhla. Lezi zixhobo zanamuhla zivame ukuhlanganisa idivayisi yakudala yokuthola umsindo emisipha yezinhliziyo, nangomsebenzi okhethekile we-Doppler ultrasound, okuvumela odokotela ukuba babone isiqondiso namandla okugeleza kwegazi kuwo wonke amakamelo enhliziyo. Kufanele kuqaphele ukuthi umsebenzi onjalo ubaluleke kakhulu ekunqumeni izinkomba ezihlukahlukene zomsebenzi wenhliziyo, kanye nokuthola izifo ezinzulu ezinhlathini ze-valvular heart.

Iziphi izifo ezingatholakala uma usebenzisa inqubo ye-ultrasound yenhliziyo?

Ngokuvamile, odokotela kule nqubo banakelela ngokukhethekile ubukhulu bendawo yamagumbi ezinhliziyo, kanye nezinguquko ekubunjeni kwezindonga zamakamelo. Ngaphezu kwalokho, ukushicilelwa kanye nomsebenzi wazo wonke amagagasi emagumbini enhliziyo, ukuhamba kwensimu yenhliziyo kanye nezinye izinkomba zokusebenza kwe-myocardial kuhlolwa. Uma odokotela bebona ushintsho oluphuthumayo kwesinye isinye noma esinye isibonakaliso nomgwamanda emzimbeni womuntu, lokhu kubonisa ngokuqondile izifo zenhliziyo ezinzulu enhliziyweni yesiguli.

Futhi, idivayisi ingathola izinkinga ezihlukahlukene zokuzalwa kwangaphakathi enhliziyweni, ngisho nasezinganeni ezisanda kuzalwa. Kulezo zifo zenhliziyo ezibelethwe kaningi ngokuvamile odokotela zihlanganisa iqembu lezinkinga eziningi ezakhiweni jikelele kanye nesakhiwo sensimu yenhliziyo. Ngokuvamile, zonke izibonakaliso zesifo zivele ngisho nasesimweni sokubeletha, futhi isimo senhliziyo yengane yesikhathi esizayo sithinteka ngemiphumela yezimo ezingathandeki ezivela emvelweni wangaphandle kumntwana osathuthuka. Ngakho-ke, ukudlulisa i-ultrasound yenhliziyo akudingekile kuphela kubantu abadala, kodwa futhi kubantwana abancane kakhulu.
