Ukuzama ukuqonda kangcono ukuthi inhliziyo yomuntu isebenza kanjani, iqembu lonjiniyela nososayensi abavela eHarvard University e-United States bakhe umugqa irobhothi ohamba ngamapulse akhanyayo. Njengoba kungabonakala esithombeni esitholakala ngenhla kwale migqa nakuvidiyo kokufakwayo okunwetshiwe, sikhuluma ngedivayisi ethambile eyakhiwe, njengoba idlulisiwe, yamangqamuzana enhliziyo yegundane ahlanganiswe nethambo legolide.
Umqondo wokudala i-ray robot ngokuyisisekelo wavela lapho onjiniyela bawo, belungiselela iphrojekthi ehlobene nezinkinga zenhliziyo, bebona ukuthi a umugqa ufana ncamashi nobuso be-endocardiumulwelwesi olumaphakathi ngaphakathi kwamagumbi enhliziyo. Ngemuva kwalokhu kutholwa, izingqondo zabo zasheshe zacabanga izinzuzo zokukwazi ukwenza uhlelo oluzolingisa ukunyakaza kwabo kusetshenziswa amaseli aphilayo.
Ukwakha irobhothi le-raya kungavumela ukutadisha ukusebenza kwenhliziyo yomuntu.
Akumangalisi ukuthi, ukuze bakwazi ukwakha umugqa ngendlela engaqondakali, bekufanele basebenzise amanye Amaseli enhliziyo yamagundane angama-200.000 ku-elastomer. Lokhu bese kubekwa esakhiweni esime njengomugqa onosayizi ongaba yi-160 mm, okukodwa eshumini ngosayizi wenhlanzi yasekuqaleni. Ukufeza ukunyakaza, ososayensi baguqula amangqamuzana enhliziyo ukuze azwele ekukhanyeni futhi ahambisane nemicabango.
Ekuvivinyweni okwenziwe kuze kube manje elabhoratri, iqembu eliphethe ukwenziwa kwaleli robhothi elikwaziyo likwazi ukuqondisa irobhothi ngakwesokunene nangakwesobunxele ngokuguqula ukuma kwamapulisi akhanyayo. Ijubane lingalawulwa ngokulungisa imvamisa yokukhanya. Ngokusho kwezitatimende zika- Kit parker, umholi wocwaningo:
Umgomo oyinhloko ukuqonda kangcono isifo senhliziyo nenhliziyo yomuntu ngokuguqula ubunjiniyela ezinye izinhlobo zokupompa imisipha esizibonayo emvelweni.
