Ukuhluka kwezinga lentliziyo (HRV) kukubonakalisa ukutshintshwa kwexesha lezithintelo zenhliziyo ngokumalunga nomgangatho ophakathi. Le propati yeenkqubo ze-biological ihambelana nesidingo sokulungelelanisa umzimba womntu kwizifo kunye nokutshintsha imeko. Ukuchasana kubonisa indlela intliziyo ithatha ngayo impembelelo yezinto ezahlukeneyo zangaphandle nangaphandle.
Kutheni kubalulekile ukwenza uhlalutyo lwe-HRV?
Inkqubo yokulungelelaniswa kwendalo kunye nemigqaliselo eyahlukeneyo idinga inkcitho yenkcazelo yayo, izibonelelo zamandla kunye namandla. Ngeenguqu ezahlukahlukeneyo kwimeko yangaphandle okanye ukuphuhliswa kwanoma yiyiphi imfuyo ukuze kugcinwe i-homeostasis, amazinga aphezulu okulawula inkqubo ye-cardiovascular start to act. Uhlalutyo olubonakalayo lwenkohlakalo yexabiso lentliziyo lisivumela ukuba siqikelele ngendlela eyiyo ngayo inxibelelaniso nezinye iinkqubo. Olu hlobo loviwo lusetyenziswa ngokuthe ngqo kwiinkqubo zokuxilonga, ngenxa yokuba kukho naziphi na iziganeko zithembekileyo zibonakalisa izibonakaliso ezahlukeneyo zomsebenzi wemvelo yendalo, umzekelo, ukulinganiswa kwemifuno.
Ukuvavanywa kokuhluka kwentlawulo yenhliziyo kwenziwa ngeendlela ezimbini:
- Uhlalutyo lwexesha - umzekelo olula wokulinganisa kwi-domain time is calculation of the deviation of the length of intervals between contractions of the heart muscle.
- Ukuhlalutya ngokuphindaphindiweyo- kubonakalisa ukulandelelana kweentlobo zomzimba, oko kukuthi, kubonisa utshintsho kwinani labo kwimiba eyahlukeneyo.
Yintoni ukuphambuka kweso siqhelo se-HRV?
Ukuba ukuhluka kwesantya senhliziyo kuyancitshiswe ngokukhawuleza, oku kungabonisa i- infarction ephawulekayo ye- myocardial . Le meko ibonakala nakwizigulane eziphethwe ngu:
- ischemic disease;
- isifo sikashukela;
- I-Guillain-Barre syndrome ;
- isifo soxinzelelo;
- multiple sclerosis;
- Isifo sikaParkinson.
Ukuhluka kwezinga lentliziyo lihlala liphantsi kwizigulane ezine-uremia kunye nezigulane ezithatha iziyobisi ezifana ne-Atropine. Uphuhliso oluphantsi lwe-HRV uhlalutyo lunokuthetha ngokungafezeki kwenkqubo ye-neon autonomic kunye nezifo zengqondo. Iiparameters zesifundo zisetyenziselwa ukuhlola ubunzima besifo. Ukuhluka kwesantya senhliziyo kuya kunxaxha kakhulu kwinto eqhelekileyo ekudakaleni, kwi-syndrome yokutshatyalaliswa ngokomzimba kunye nezinye iingxaki zengqondo.
