Isilinganiso senhliziyo. Incazelo

Ukuqhuma kuyinto inhlangano oscillatory of izindonga of isifo somzimba of nature impulsive. Lezi ziguquko zenzeka ngenxa yezinguquko egazini legazi ngaphakathi kwazo ezinqunyweni zomzimba. Imvelo (isigqi, ukuhlupha, ukugcwalisa, imvamisa) ye-pulse incike emsebenzini wenhliziyo kanye nesimo se-arteries. Ukuguquka ngendlela yokuguquka kungaba ngenxa yokucindezeleka kwengqondo, umsebenzi, izinguquko ekushiseni okuzungezile, ukufakwa kwezidakamizwa ezithile (izidakamizwa, utshwala nabanye) emzimbeni.

Izinga lokushayela lilinganiswa ngokusebenzisa izindlela ezihlukahlukene. Okulula kakhulu umuzwa. Kuqhutshwa, njengombuso, phansi kwesigcawu sokuqala (esikhulu) emgqeni wesigcawu se-frontarm engakwesobunxele. Zizwa umshini omsakazo. Ukuze izinga lokushayela lizwakale ngokucacile, isandla kufanele sibe sezwe elikhululekile, silale ngaphandle kokucindezeleka, ngokukhululekile.

Kumele kuthiwa ukukhishwa kwamanzi kunamanye amabhethri (isibonelo, izidakamizwa ze-ulnar, zesifazane, zesikhashana kanye nezinye). Isilinganiso senhliziyo evamile singukushaya okungamashumi ayisikhombisa kuya kwangu-80 ngomzuzu.

Ukubala inani lezinkinobho kuqhutshwa kungakapheli imizuzwana eyishumi nanhlanu noma amashumi amathathu. Inani elitholiwe liphindwe kabili noma amane, ngokulandelana. Ngakho-ke, uthola isilinganiso se-pulse ngomzuzu. Uma kukhona izinguquko eziphawulekayo kwinombolo yezidlidliza, ukubalwa kwenziwa ngomzuzu owodwa, ukuze ugweme iphutha. Emlandweni wendaba, irekhodi lenziwa nsuku zonke noma ijika le-pulse ludonseleka ngokufanayo emgqeni wokushisa ekhasini lokushisa.

Inombolo yokuqhaqhazela ngaphansi kwezimo zomzimba inqunywa ithonya lezici eziningi.

Ngakho, izinga lokushayela lixhomeke eminyakeni. Njengomkhuba wokubonisa, inani lokushintsha liyehliswa ngobudala. Isilinganiso esiphakeme kakhulu sokushukela ezinganeni eminyakeni yokuqala yokuphila.

Inani lezinhlungu lixhomeke esimweni somsebenzi we-muscular. Ngokumelene nesimo sokuzikhandla ngokomzimba, i-pulse ijubane. Ukwanda kuyenzeka futhi ngokumelene nesizinda semithwalo yemvelo.

Ukuguqulwa kwenani lokukhishwa kwe-oscillations kubuye kwenzeke kuye ngesikhathi sosuku. Ngakho, ebusuku ngesikhathi sokulala, izinga lokushaywa komzimba liyehla.

Inani lezinxephezelo lihlobene ngokuqondile nocansi. Kutholakale ukuthi kubantu besifazane izinga lokushaywa kwesisindo liphindwe izikhathi eziyisihlanu kuya kweziyishumi kunamadoda.

Ubuningi bokungcola buyithonya kakhulu izinto ezihlukahlukene. Isibonelo, i-adrenaline, i-atropine, i-caffeine, utshwala yandisa imvamisa, kodwa i-digitalis, ngokuphambene nalokho, iyancipha.

Inombolo yezidakamizwa ezinkulu kunamaphesenti ayisishiyagalolunye ngomzuzu kuthiwa i-tachycardia. Ukusheshisa kwe-pulse kubonakala ekuzikhandla ngokomzimba, ukucindezeleka ngokomzwelo, izinguquko endaweni yesitokisi. I-tachycardia ehlala isikhathi eside ingabangelwa ukunyuka kokushisa. Ngokumelene nesimo somkhuhlane, ukwanda kwezinga lokushisa ngezinga elilodwa kuholela ekukhuphukeni kwentengo yenhliziyo nge-8-10 beats / min. Isimo sesiguli sibubi nakakhulu, ukuqina kwamanqamuleli kunqamule inani lokushisa. Ingozi ekhethekile yisimo lapho inani lezinxephezelo landa ngokudonsa ekushiseni komzimba.
