Kuumuthi, aHolter qaphawuhlobo lwe-ambulensii-electrocardiographyidivayisi, idivayisi ephathekayo yeukuqapha inhliziyo(iukuqaphakweumsebenzi kagesi wesimiso senhliziyo) okungenani amahora angama-24 kuye kwangama-48 (ngokuvamile amasonto amabili ngesikhathi).
Ukusetshenziswa okuvame kakhulu kwe-Holter ukuqaphaI-ECG inhliziyoumsebenzi (i-electrocardiographynoma i-ECG).Isikhathi sayo esinwetshiwe sokurekhoda kwesinye isikhathi siwusizo ekubukweni ngezikhathi ezithilei-arrhythmia yenhliziyookungaba nzima ukukukhomba esikhathini esifushane.Ezigulini ezinezimpawu zesikhashana, aukuqapha umcimbi wenhliziyookungase kugqokwe inyanga noma ngaphezulu kungasetshenziswa.[1]
Lapho isetshenziselwa ukutadisha inhliziyo, njenge-electrocardiography evamile, i-Holter monitor irekhoda amasignali kagesi asuka enhliziyweni ngochungechunge lwe-electrocardiography.ama-electrodeenamathiselwe esifubeni.Ama-Electrode abekwa phezu kwamathambo ukuze kuncishiswe izinto zobuciko ezivela ekusebenzeni kwemisipha.Inombolo nendawo yama-electrode kuyahlukahluka kuye ngemodeli, kodwa amamonitha amaningi akwa-Holter asebenzisa phakathi kokuthathu nesishiyagalombili.Lawa ma-electrode axhunywe entweni encane exhunywe ebhandeni lesiguli noma elenga entanyeni, egcina umbhalo womsebenzi kagesi wenhliziyo phakathi naso sonke isikhathi sokuqopha.Isistimu ye-Holter ehamba phambili engu-12 nayo iyatholakala uma inembeI-ECGulwazi lwesignali luyadingeka ukuze kuhlaziywe ubunjalo obuqondile nomsuka wesignali yesigqi.
Umqophi
Usayizi werekhoda uyahluka kuye ngomkhiqizi wocingo.Izilinganiso ezimaphakathi zamamonitha e-Holter zanamuhla cishe zingu-110x70x30 mm kodwa ezinye zingu-61x46x20 mm kuphela futhi zinesisindo esingu-99 g.[6]Iningi lamadivayisi lisebenza ngamabiliAmabhethri we-AA.Uma kwenzeka amabhethri ephelile, amanye ama-Holters avumela ukushintshwa kwawo ngisho nangesikhathi sokuqapha.
Iningi lama-Holters liqapha i-ECG ngamashaneli amabili noma amathathu kuphela (Qaphela: kuye ngomkhiqizi, izibalo ezihlukene zomthofu nezinhlelo zokuhola ziyasetshenziswa).Umkhuba wanamuhla uwukunciphisa inani lokuhola ukuze uqinisekise ukunethezeka kwesiguli ngesikhathi sokurekhoda.Nakuba ukurekhoda kweziteshi ezimbili/ezintathu sekusetshenziswe isikhathi eside emlandweni wokuqapha we-Holter, njengoba kushiwo ngenhla, i-12 channel Holters isanda kuvela.Lezi zinhlelo zisebenzisa isistimu yokuhola ye-Mason-Likar yakudala, okungukuthi ikhiqiza isignali ngefomethi efanayo nangesikhathi se-ECG evamile yokuphumula kanye/nomaukuhlolwa kokucindezelekaukulinganisa.Lawa ma-Holters kwesinye isikhathi angahlinzeka ngolwazi olufana nalolo lwe-aI-ECGukuhlolwa kokuhlolwa kokucindezeleka.Zibuye zifaneleke lapho kuhlaziywa iziguli ngemuvai-myocardial infarction.Okurekhodiwe okuvela kulaba baqaphi abaholayo abayi-12 kunokulungiswa okuphansi kakhulu kunalokho okuvela ku-ECG eholayo engu-12 futhi kwezinye izimo kuboniswe ukunikeza ukumelela kwengxenye ye-ST edukisayo, nakuba amanye amadivayisi avumela ukusetha imvamisa yesampula ifike ku-1000 Hz ukuze izivivinyo zezinjongo ezikhethekile ezifana nokutholwa “kokungenzeka sekwephuzile”.
Okunye okusha ukufakwa kwenzwa yokunyakaza kwe-triaxial, erekhoda umsebenzi womzimba wesiguli, futhi ekuhlolweni nasekucubunguleni isofthiwe, ikhipha izimo ezintathu zokunyakaza: ukulala, ukuma, noma ukuhamba.Amanye amadivaysi esimanje nawo anekhono lokurekhoda idayari yesiguli esizwayo engalalelwa kamuva udokotela.Le datha isiza udokotela wenhliziyo ukuthi abone kangcono izehlakalo maqondana nomsebenzi wesiguli kanye nedayari.
