Ukuhluka kwesilinganiso senhliziyo (i-HRV) ukubonakalisa ukushintshashintsha kwemvamisa yezinqamuzana zenhliziyo ngokuphathelene nesilinganiso sawo esijwayelekile. Le ndawo yezinqubo zezinto eziphilayo ihlotshaniswa nesidingo sokuvumelanisa umzimba womuntu nezifo nokushintsha izimo zemvelo. Ukuhlukahluka kubonisa ukuthi inhliziyo ithinta kanjani umthelela wezinto ezihlukahlukene zangaphakathi nangaphandle.
Kungani kubalulekile ukwenza ukuhlaziywa kwe-HRV?
Inqubo yokuguquguquka kwesimo semvelo kuya ekuthandeni okuhlukahlukene idinga ukusetshenziswa kwemininingwane yayo, imithombo yamandla kanye namandla. Ngezinguquko ezihlukahlukene emvelweni wangaphandle noma ukuthuthukiswa kwanoma yikuphi ukugula ukuze kugcinwe i-homeostasis, amazinga aphezulu okuphatha uhlelo lwe-cardiovascular aqala ukwenza. Ukuhlaziya okubonakalayo kokuhluka kwezinga lenhliziyo kusenza sikwazi ukulinganisa ukuthi isebenza kanjani ngezinye izinhlelo. Lolu hlobo lokuhlolwa lusetshenziselwa ngokugcwele ekuxilongweni okusebenzayo, ngoba kunoma yiziphi izimo libonisa ngokuthembekile izinkomba ezihlukahlukene ezibalulekile zemisebenzi yemvelo yenyama, isibonelo, ibhalansi yemifino.
Ukuhlolwa kokuhluka kwenhliziyo kwenziwa ngezindlela ezimbili:
- Ukuhlaziywa kwesikhathi - isibonelo esilula sokulinganisa esizindeni sesikhathi ukubalwa kokuphambana nobude bezinhlangothi eziphakathi kweziphambano ezilandelanayo zomzimba wenhliziyo.
- Ukuhlaziywa kwamavamisa - kubonisa ukujwayela kwezinhliziyo zomzimba, okungukuthi, kubonisa ushintsho kwinombolo yabo ezinhlobonhlobo zama frequency ezahlukene.
Kuyini ukuphambene nomkhuba we-HRV?
Uma ukuhluka kwesilinganiso senhliziyo kuyanciphisa kakhulu, lokhu kungase kubonise ukuthi i- infarction eyingozi ye-myocardial . Lesi simo sibonakala nakwabagulayo abavela:
- ischemic;
- isifo sikashukela mellitus;
- I-Guillain-Barre syndrome ;
- isifo sofuba;
- i-sclerosis amaningi;
- Isifo sikaParkinson.
Ukuhluka kwesilinganiso senhliziyo ngaso sonke isikhathi kunciphile kweziguli ezine-uremia kanye neziguli ezithatha izidakamizwa ezifana ne-Atropine. Imiphumela ephansi yokuhlaziywa kwe-HRV ingakhuluma ngokungasebenzi kahle kwesimiso sezinzwa ezizimele kanye nezifo ezingokwengqondo. Imingcele yocwaningo isetshenziselwa ukuhlola ubunzima besifo. Ukuhluka kwesilinganiso senhliziyo nakho kuyaphambuka kakhulu kunomkhuba wokucindezeleka, isifo sokushisa ngokomzwelo nezinye izinkinga ezingokwengqondo.
