Ukucindezela komzimba kungenye yezimpawu eziyinhloko zesimo sempilo yabantu, okunikeza umqondo hhayi nje ngomsebenzi wegazi, kodwa futhi nangomzimba jikelele. Inani lalo linamanani amabili: phezulu (systolic) nokucindezela okuphansi (diastolic). Ake sihlale ngokuningiliziwe embonini ye-diastolic bese sicabangela ukuthi kuncike ekutheni, futhi kungani amanani ayo angashintsha ngendlela eyodwa nakwezinye.
Iyini ingcindezi ye-diastolic ebusayo futhi iyini evamile?
Ubukhulu bomfutho we-diastolic bubonisa amandla okucindezelwa kwegazi lapho i-muscle ikhululekile ngokuphelele (ngesikhathi se-diastole), isb. lapho inhliziyo iphumula. Lona ukucindezelwa okuphansi kunazo zonke emithanjeni, ethwala igazi ezithombeni nasezikhunjini, ezixhomeke ngokuqondile ngethoni ye-vascular and elasticity. Ngaphezu kwalokho, ivolumu yenani legazi nesilinganiso senhliziyo kubandakanyeka ekubunjweni kwe-index ye-diastolic ingcindezi.
Ngokujwayelekile, kubantu abanempilo, izinga lokucindezela kwe-diastolic lihluka phakathi kuka-65 ± 10 mm Hg. Njengoba uneminyaka yobudala, leli xabiso lihluka kancane. Ngakho-ke, kubantu abathintekayo, ngokuvamile ingcindezi ephansi ingaphansi kuka-70 - 80 mm emfuleni, futhi emva kweminyaka engamashumi amahlanu itshintsha phakathi kuka-80-89 mm Hg.
Izimbangela zokucindezela kwe-diastolic
Ngaphambi kokucabangela ukuthi yiziphi izifo ezingase zihlotshaniswe nokwanda kwe-diastolic ingcindezi, kufanele kuqashelwe ukuthi icala elilodwa lokunyuka kwalo (kanye nokunciphisa) alisho lutho. Kuye kwacatshangelwa kuphela izinkomba ezishintshashintshayo, ngoba ukucindezela komzimba kungashintshwa okwesikhashana ngenxa yezici ezihlukahlukene (izinga lokushisa elincane, izimo ezicindezelayo, umsebenzi womzimba, njll). Ngaphezu kwalokho, ingcindezi ye-diastolic ingashintshwa ngokumelene nesimo sokunyuka kwengcindezi ekhulayo, evamile noma eyancishisiwe, okuyinto ochwepheshe abayicabangayo.
Izimbangela zokucindezela okukhulu kwe-diastolic ezimweni eziningi yizi:
- izifo ze-kidney kanye ne-adrenal gland;
- Izifo zegciwane le-thyroid;
- isifo se-musculoskeletal system;
- shintsha ivolumu yesifo senhliziyo.
Kwezinye izifo ezithathelwanayo, ukuhlushwa kwe-enzyme renin kukhulunywa kuzo, kwathinta ithoni ye-vascular futhi kuholela ekwandeni kokucindezela kwe-diastolic. Ukwanda komfutho ophansi nakho kubangelwa ama-hormone afihliwe yizigulane ze-adrenal ne-gland yegciwane.
Ukucindezela kwe-diastolic ephakeme kungabonakaliswa yizibonakaliso ezinjengokuphefumula kanzima, isizungu, ubuhlungu esifubeni. Ukweqa ngokweqile kwendlela evamile yengcindezi engezansi kuholela ekubonweni okungekho kahle, ukuhlinzeka ngegazi ebuchosheni, ingozi eyengeziwe yokwehla kwesifo sohlangothi kanye ne-myocardial infarction.
Izimbangela zokunciphisa ukucindezeleka kwe-diastolic
Ngenkinga yokunciphisa i-diastolic, umuntu uvame ukuzizwa ekhululekile, ukulala, isizungu , kanye nokukhanda ikhanda. Lokhu kungabonwa ngezifo ezilandelayo:
- isifo sofuba ;
- izifo zesigcawu sesisu;
- ukwehluleka kwe-valve;
- izifo ezithathelwanayo;
- ukuwohloka komzimba, njll.
Kwabesifazane, ukucindezeleka okuphansi kwe-diastolic ngezinye izikhathi kubonakala ngesikhathi sokukhulelwa. Kufanelekile ukwazi ukuthi isimo esinjalo siyingozi, ngoba ngenxa yalokho, ingane engenayo i-oxygen nezakhi. Futhi, ukuncipha kwengcindezi (nokwandisa) kungenzeka ngenxa yokwelapha ngemithi ethile.
