Ukuguqulwa kuyinkomba ebalulekile yokuthuthukiswa kwezempilo kanye nokuqiniswa kwe-fetus. Uma kungazelelwe kunezimo ezingathandeki zekusasa lomntwana, ushintsho ekushaya kwenhliziyo kuqala lukhombisa lokhu. Ukulinganisa imvamisa kanye nemvelo yezinhliziyo zenhliziyo ye-fetal yenziwa kulo lonke ukukhulelwa.
Izibonakaliso zokuqala ze-palpitations
Ukuxilongwa kwe-ultrasonic kunganqunywa ngokunemba uma kwenzeka i-palpitation ye-fetus. Ngokuvamile inhliziyo ikhiwa ngesonto lesine lokukhulelwa, futhi ukushaya kwenhliziyo kwesisu kuzwakala lapho kuvela izinhlamvu zokuqala eziqhubekayo zokuqhuma.
Ukusungula ngamuphi isonto ozwa ukushaya kwenhliziyo kunezindlela ezimbili ze-ultrasound:
- I-ultrasound ehamba phambili iyenziwa kuphela ngokusho kwezinkomba zikadokotela, uma kukhona ukwephulwa kwenkambo yokukhulelwa kuqaphela. Kulesi simo, inzwa ifakwa ngaphakathi kwesifazane, okusiza ukuzwa inhliziyo ye-fetal ngaphambi kweviki lesihlanu kuya kwesithupha lokukhulelwa.
- Ngisiphi isonto i-palpitation ingatholakala ngokuqhuba i-ultrasound yomzimba evamile, lapho inzwa ihlola udonga lwesisu esiswini. Ngalendlela, ukuguqulwa kwe-pulsation kunqunywe kusuka emavikini angu-6-7 okukhulelwa.
Omama abaningi abasha, ukufunda amasonto ambalwa ukulalela ukushaya kwenhliziyo, bakholelwa ukuthi kufanele ngandlela-thile bazizwe izinhliziyo ze-fetal futhi besabe kancane ngaphandle kokuzwa noma yiziphi izinguquko. Kodwa-ke, ngesikhathi esifanayo ngisho nodokotela ekuhlolweni okujwayelekile abakwazi ukuzwa ukushaya kwenhliziyo, lokhu kungenzeka akuveli kuze kube sekupheleni kweviki lama-20 lokukhulelwa. Kumele kuthiwa owesifazane okhulelwe akazwa imizwa yenhliziyo yesisu, kodwa uzwa kuphela ukuhamba kwengane.
Inkomba ebalulekile yentuthuko evamile ye-fetal yimiyalo yiphi isonto futhi yikuphi ukuvama kwenhliziyo okulalelwayo:
- Lapho useneminyaka engama-6-8 amasonto ubudala, izinga lentliziyo ye-fetal kufanele libe yizintambo ezingu-130 ngomzuzu;
- emasontweni ayishumi okukhulelwa, lesi sibonakaliso silingana nokunciphisa ama-170-190;
- inani lezinhliziyo zomzimba we-muscle we-fetus ngesonto lama-13 lokukhulelwa ngu-140-160 ukushaya ngomzuzu, futhi uhlala kuze kube sekuzalweni uqobo.
Kusukela ngeviki lesi-5 lokukhulelwa, lapho i-palpitation ye-fetus yenzeka, futhi ngaphambi kokuzalwa kwengane, lesi sibonakaliso esibalulekile sidinga ukuqapha okuqhubekayo. Ngakho-ke, umama wesikhathi esizayo kufanele avakashele udokotela njalo futhi ahlole zonke izivivinyo ezibekwe umchwepheshe wezifo zogciwane. Emasontweni amangaki ukushaya kwenhliziyo kuzwakala ngokuzwakalayo ngaphandle kwemishini ekhethekile, udokotela unquma ngosizo lwe-stethoscope yombelethisi. Ngokuvamile, kusukela ku-trimester yesithathu yokukhulelwa, ngesikhathi sokwamukelwa ngamunye umbelethisi ulalela izinga lenhliziyo yengane futhi urekhoda yonke idatha ekhadini elikhulelwe. Uma ukwephulwa kancane kwenhliziyo, izinyathelo eziphuthumayo zithathwa ukuze zibone izimbangela futhi zilondoloze i-fetus.
