Dance carotid: Izimbangela Nezingozi izimpawu

Abantu ababeka njalo ephakanyiswe blood pressure, noma baye bazwakalisa isifo sokuqina kwemithambo yegazi, ube imithambo abahlukene futhi lwalugobile kakhulu emathempelini bakhe nentamo.

Ziyini izimpawu syndrome

Ukuhlola entanyeni esingamahlalakhona womuntu yomthambo i-aorta, uchwepheshe ngeke ngokushesha uqaphela vibration abhanqiwe imithambo nhlangothi zombili entanyeni - the carotid lokhu umdanso. In parallel isigqi ukushaya kwenhliziyo kungase banikine amakhanda abo emuva naphambili. Lokhu kungenxa izinguquko abukhali wegazi amandla e imithambo yegazi abhanqiwe, okuyinto ukusebenzisa kuhambisana uqhoqhoqho kanye kuqhoqhoqho. Ngenxa yezwakala babangela ikhanda ukunyakaza.

Intamo bubonakala throbbing emithanjeni jugular. Ngokusho le nqubo kungabonwa ngakwesokudla ingcindezi atrial nomsebenzi inhliziyo. Zokuzikhukhumeza ngemithambo umuntu enempilo kungabonakala isikhundla lisalele.

Uphawu carotid ukudansa zingahlangana nabanye imithambo onesigqi, le nqubo kungenziwa bufakwe ngisho arteriole.

Kuleli qophelo, kuchazwe kahle Quincke ishayela lapho sicindezelwe embhedeni nail nesiphetho ngesikhathi ingcindezi mucosa ku ngalo ingaphakathi ngomlomo kanye ukuhilizisana kwesikhumba emabunzini.

besisu okusizwa ukushaya yomthambo i-aorta

Kakhulu ebonakalayo carotid umdanso kwenzeka lapho esiswini, epigastric ingxenye yakhe, futhi kwenzeka ngenxa ukukhuphuka oluqinile kokucindezelwa ka-ventricle yangakwesokudla noma ngenxa aorta ejabhile besisu. Kuhle ukubonwa okusizwa ukushaya kubangelwa i-ventricle yangakwesokudla, ngaphansi ephansi ekupheleni mahhala engxenyeni emfushane futhi encane le sternum. Hlola ukuma isiguli kangcono.

Dance carotid aorta besisu kusobala kakhulu ebonakalayo exhale, ngesikhathi umuntu usesimweni ovundlile.

Yomthambo i-aorta ne-valve isibindi

Kukhona futhi izinhlobo ezimbili zezinkantolo okusizwa ukushaya kwesibindi:

• ukudluliselwa okusizwa ukushaya isibindi kungenxa impendulo yayo kwenhliziyo, umzimba synchronously ihamba ngendlela isiqondiso predetermined khathi
• okusizwa ukushaya kweqiniso uchungechunge izinguquko uyanda futhi uya ngokuya incipha ubukhulu kwesibindi.

Uhlobo yezwakala wesibili kungenzeka ngesikhathi umphini yomthambo i-aorta , (umdanso carotid). Khulisa (zokuzikhukhumeza) kwenzeka kanyekanye ne ngiyibona apical of inhliziyo kuyigazi. Lapho esingamahlalakhona tricuspid kuzokwenzeka okusizwa ukushaya emithambo yegazi. Lokhu kwenzeka ngenxa reverse ukugeleza kwegazi e ndima ngeke kahle ehlanganiswa kusukela i-ventricle yangakwesokudla ekamelweni yangakwesokudla senhliziyo. Bese kuthi-ke igazi engena phansi kunabaphostoli vena cava futhi hepatic. Yilokhu kuholela ukuvuvukala kwesibindi.
