Ukuchonga izizathu zempilo ephosakeleyo, ukuxilongwa kwezifo ze-cardiovascular, i-systolic kunye ne-diastolic ingcinezelo isoloko ilinganiswa - yintoni, kungekhona wonke umntu uyazi, nangona esebenzisa le ngqiqo rhoqo. Kubalulekile ukuba uqaphele ukuba ubuncinane ingcamango ebanzi yentsingiselo kunye nendlela yokwakhiwa kwengcinezelo kubaluleke kakhulu.
Uxinzelelo lwe-systolic kunye ne-diastolic lithetha ntoni?
Xa ulinganisa uxinzelelo lwegazi ngokweendlela eziqhelekileyo zeKorkov, umphumo unamanani amabini. Ixabiso lokuqala, elibizwa ngokuba yingcinezelo esezantsi okanye i-systolic, ibonisa uxinzelelo lokuba igazi lisebenza kwiinqanawa ngexesha lokuqhekeka kwenhliziyo (i-systole).
Isalathisi sesibini, ingcinezelo esezantsi okanye i-diastolic, ingcinezelo ngexesha lokuphumla (i-diastole) yesisu senhliziyo. Yenziwa ngokunciphisa imithwalo yegazi yomhlaba.
Ukwazi ukuba yintoni ingcinezelo ye-systolic kunye ne-diastolic ithetha, unokwenza izigqibo malunga nesimo senhliziyo. Ngaloo ndlela, iingqungquthela eziphezulu zixhomekeke kwiinkcenkcesho zeentliziyo zentliziyo, ubunzima bokuthi igazi lixakeke. Ngoko ke, izinga leengcinezelo eziphezulu libonisa ukusebenza kwe-myocardium, amandla kunye nentliziyo.
Ixabiso elingaphantsi kwexinzelelo, kwakhona lixhomekeke kwizinto ezi-3:
- ukunyaniseka kunye nefuthe yemithambo yegazi;
- umthamo wegazi ngokupheleleyo;
- izinga lentliziyo.
Kwakhona, isimo sempilo sinokugwetywa ngokubala isahluko samanani phakathi kwe-systolic kunye noxinzelelo lwe-diastolic. Kwiyeza, eli lathisi libizwa ngokuba nguxinzelelo lwe-pulse kwaye libhekwa njengenye yezinto ezibalulekileyo kunye ezibalulekileyo.
Isiqhelo sohlukwano phakathi koxinzelelo lwe-systolic kunye ne-diastolic
Ngomntu onempilo, uxinzelelo lwe-pulse kufuneka lube phakathi kwe-30 no-40 mm Hg. Ubugcisa. kwaye kungabi ngaphezu kwe-60% yezinga lexinzelelo le-diastolic.
Ngokubaluleka kwexabiso elibhekisiwe, umntu unokufumana izigqibo ngokuphathelele kwimeko kunye nokusebenza kwenkqubo ye-cardiovascular system. Ngokomzekelo, xa uxinzelelo lwe-pulse luphakamileyo kunamanani asetiweyo, uxinzelelo oluphezulu lwe-systolic luboniswa ngoluhlu oluqhelekileyo okanye oluye lwahla lwe-diastolic, inkqubo yokuguga yezitho zangaphakathi ikhawuleza. Ininzi yazo zonke, iintso, intliziyo kunye nengqondo zichaphazelekayo. Kubalulekile ukuba uqaphele ukuba i-pulse excessive, kwaye ngenxa yoko-ingcinezelo ephezulu ye-systolic kunye ne-diastolic ephantsi ibonisa umngcipheko wangempela we-fibrillation ye-atrial kunye nezinye izifo zentliziyo.
Kwiimeko ezichasayo, ngokunyanzeliswa kwe-pulse ephantsi kunye nokuhla kweyantlukwano phakathi koxinzelelo lwe-systolic kunye ne-diastolic, kukholelwa ukuba kukho ukwehla kwenani lentliziyo. Le ngxaki ingavela kwimvelaphi yokuhluleka kwentliziyo , i-aortic stenosis, i-hypovolemia. Kwixesha elide, ukuxhatshazwa kwengcinezelo yegazi yeendonga zee-vascular peripheral kwandisiwe.
Xa kubalwa uxinzelelo lwe-pulse, kubalulekile ukunyamekela ukuthotyelwa kwexabiso eliqhelekileyo loxinzelelo lwe-systolic kunye ne-diastolic. Ngokufanelekileyo, kwi-dialta ye-tonometer, inani lama-120 kunye ne-80 kufuneka libhekiswe kumanani aphezulu nakwezantsi, ngokulandelanayo. Kukho ukuhluka okuncinane kuxhomekeke kwiminyaka, indlela yokuphila yomntu.
Uxinzelelo lwe-systolic olwengeziwe luvame ukuphazamisa ukutshabalala kwengqondo, ischemic, imivimbo enzima . Ukunyuka kwengcinezelo ye-diastolic iqulethwe zizifo ezingapheliyo zeentso kunye neenkqubo zokucoca, ukuphulwa kwe-elasticity yeendonga ze-vascular.
