Uxinzelelo lwe-arterial ungomnye wabakishi abalulekileyo bobuqu bempilo yabantu, obunikela ingcamango nje kuphela ngomsebenzi wegazi, kodwa nangomzimba ngokubanzi. Inani lalo linamanani amabini: phezulu (i-systolic) kunye nezantsi (i-diastolic). Makhe sihlale kwiinkcukacha ezininzi kwi-diastolic exponent kwaye siqwalasele oko kuxhomekeke kuyo, kwaye kutheni ukuba izindinganiso zaso zingatshintshela kwelinye icala kunye nolunye.
Ingaba yintoni uxinzelelo lwe-diastolic echaphazelekayo kwaye yintoni na imeko yayo?
Ubukhulu bexinzelelo lwe-diastolic lubonisa amandla apho uxinzelelo lwegazi lugxininisa imirhobho ngexesha le-heart muscle ekhululekile ngokupheleleyo (ngexesha le-diastole), i-e. xa intliziyo iphumle. Olu luxinzelelo oluphantsi kakhulu kwimibhobho, ephethe igazi kwizitho kunye nezicubu, ezixhomekeke ngokuthe ngqo kwi-tone ye-vascular kunye ne-elasticity. Ukongezelela, umthamo wegazi kunye nentlawulo yenhliziyo ibandakanyeka ekubunjweni kwenkcazo yoxinzelelo lwe-diastolic.
Ngokuqhelekileyo, kubantu abaphilileyo, izinga lokunyanzeliswa kwe-diastolic lihluka phakathi kwama-65 ± 10 mm Hg. Xa uneminyaka yobudala, eli xabiso lihluka kancane. Ngaloo ndlela, kubantu abaneminyaka ephakathi, uxinzelelo oluphantsi luhlala luphakathi kwama-70 ukuya kuma-80 mm emlambo, kwaye emva kweminyaka engama-50 lushintsha phakathi kwama-80-89 mm Hg.
Izizathu zokunyuka kwengcinezelo ye-diastolic
Ngaphambi kokuqwalasela ukuba zeziphi izifo ezinokuthi zidibaniswe nokunyuka kwexinzelelo lwe-diastolic, ku funeka kuqatshelwe ukuba elinye icala lokunyuka kwalo (kunye nokunciphisa) alisho lutho. Kuye kuthathelwa ingqalelo ngokukhawuleza izicatshulwa, kuba ingcinezelo yomsinga ingatshintshwa okwethutyana ngenxa yeemeko ezahlukeneyo (ubushushu obumgangatho ophezulu, iimeko ezixinzelelekileyo, umsebenzi wokwenyama, njl.). Ukongezelela, uxinzelelo lwe-diastolic lungatshintshwa ngokusuka kwimvelaphi yokunyuka, ukuqhelekileyo okanye ukunciphisa uxinzelelo ophezulu, okwenziwa iingcali.
Izizathu zengcinezelo ephezulu ye-diastolic kwiimeko ezininzi zi:
- izifo ze-kidney kunye ne-adrenal gland;
- Izifo zengqondo ye-Thyroid;
- isifo se-musculoskeletal system;
- utshintshe kwivolumu yesifo senhliziyo.
Kwezinye izifo zonyango, ingxube ye-enzyme renin eyenziwe kuyo iyakwanda, echaphazela ithoni ye-vascular kwaye ibangela ukwanda kwenycinezelo ye-diastolic. Ukwanda kweengcinezelo ezincinci kubangelwa ngama-hormone afihliwe yi-adrenal gland kunye ne-thyroid gland.
Uxinzelelo oluphezulu lwe-diastolic lungabonakaliswa yimpawu ezifana nobunzima bokuphefumula, utywala, intlungu kwisifuba. Ukugqithisa ixesha elide lomgangatho wengcinezelo esezantsi kukhokelela ekubonweni okungahambi kakuhle, ukunikezelwa kwegazi kwingqondo, ukwanda komngcipheko we-stroke kunye ne-myocardial infarction.
Izizathu zokunciphisa uxinzelelo lwe-diastolic
Ngoxinzelelo lwe-diastolic elincinci, umntu uvakalelwa kukuba, ukulala, ukuzondwa , kunye nentloko. Oku kungabonwa ngolu hlobo lulandelayo:
- isifo sofuba ;
- izifo zesigxina sesisu;
- ukuhluleka kwe-valve;
- zifo;
- ukucima amanzi emzimbeni, njl
Kubasetyhini, ukunyanzeliswa kwe-diastolic ephantsi ngezinye ixesha kubonwa ngexesha lokukhulelwa. Kufanelekile ukwazi ukuba imeko enjalo iyingozi, kuba ngenxa yoko, umntwana engenalo i-oxygen kunye nezondlo. Kwakhona, ukunciphisa uxinzelelo (kunye nokwanda) kunokwenzeka ngenxa yonyango ngamachiza athile.
