Izintambo eziholayo ze-ECG ziyizingxenye ezibalulekile zokuqapha isiguli, okuvumela ukutholwa okunembile kwedatha ye-electrocardiogram (ECG). Nasi isingeniso esilula sezintambo eziholayo ze-ECG ezisuselwe ekuhlukaniseni umkhiqizo ukuze uziqonde kangcono.

Ukuhlukaniswa Kwezintambo Ze-ECG Nezintambo Zokuhola Ngokwesakhiwo Somkhiqizo

1.Amakhebuli e-ECG ahlanganisiwe

IAmakhebuli e-ECG ahlanganisiweyamukela umklamo omusha ohlanganisa kakhulu ama-electrode nezintambo, okuvumela ukuxhumana okuqondile kusukela ekupheleni kwesiguli kuya kumqapha ngaphandle kwezingxenye eziphakathi. Lesi sakhiwo esilula asenzeli nje kuphela isakhiwo sibe lula kodwa futhi sisusa izixhumi eziningi ngokuvamile ezitholakala kumasistimu ohlobo oluhlukene oluvamile. Ngenxa yalokho, kunciphisa kakhulu ingozi yokwehluleka ngenxa yokuxhumeka okungalungile noma ukulimala kwamazwana, ukunikeza isisombululo esizinzile nesithembekile sokuqapha isiguli. Umdwebo olandelayo ubonisa ukusetshenziswa kwe-Integrated ECG Cables njengereferensi yakho.

2.ECG Trunk Cables

IIzintambo ze-ECG Trunkiyingxenye ebalulekile yohlelo lokuqapha lwe-ECG, oluhlanganisa izingxenye ezintathu: isixhumi semishini, intambo ye-trunk, nesixhumi sejoka.

3.Izintambo zokuhola ze-ECG

Izintambo ezihamba phambili ze-ECGasetshenziswa ngokuhlanganyela ECG trunk izintambo. Kulo mklamo Ohlukanisekayo, izintambo eziholayo kuphela ezidinga ukushintshwa uma zonakele, kuyilapho ikhebula le-trunk lihlala lisebenziseka, okuholela ezindlekweni zokunakekela eziphansi uma kuqhathaniswa nezintambo ezihlanganisiwe ze-ECG. Ngaphezu kwalokho, izintambo ze-ECG trunk azikho ngaphansi kokuxhunywa njalo nokunqanyulwa, okunganweba kakhulu impilo yazo yesevisi.

Izintambo ze-ECG kanye nezintambo eziholayo Ukwahlukaniswa ngesibalo sokuhola

• 3-Lead ECG Cables

Ngokwesakhiwo,Izintambo ze-ECG eziholayo ezi-3iqukethe izintambo ezintathu zokuhola, ngayinye exhunywe ku-electrode ethile. Lawa ma-electrode afakwa ezingxenyeni ezihlukene zomzimba wesiguli ukuze abone amasignali e-bioelectrical. Emisebenzini yomtholampilo, izindawo ezivamile zokubeka ama-electrode zihlanganisa ingalo yesokudla (RA), ingalo yesokunxele (LA), nomlenze wesokunxele (LL). Lokhu kulungiselelwa kwenza inhliziyo irekhodwe's imisebenzi kagesi evela kuma-engeli amaningi, ihlinzeka ngedatha ebalulekile yokuxilongwa okunembile kwezokwelapha.

•  5-Lead ECG Cables

Uma kuqhathaniswa nezintambo ze-ECG eziholayo ezi-3,Izintambo ze-ECG eziholayo ezingu-5ukucushwa kunikeza idatha kagesi yenhliziyo ebanzi ngokuthwebula amasiginali asuka kumasayithi engeziwe e-anatomical. Ama-electrode ngokuvamile abekwe ku-RA (ingalo yakwesokudla), LA (ingalo yesobunxele), RL (umlenze wesokudla), LL (umlenze wesobunxele), kanye no-V (precordial/chest lead), okuvumela ukuqapha kwenhliziyo okunezinhlangothi eziningi. Lokhu kusetha okuthuthukisiwe kunikeza odokotela imininingwane enembile nene-panoramic enhliziyweni'isimo se-electrophysiological, esisekela ukuxilonga okunembe kakhudlwana kanye namasu okwelapha aqondene nomuntu ngamunye.

•  10-Lead noma 12-Lead ECG Cables

I10-Lead / 12-Lead ECG ikhebulakuyindlela ephelele yokuqapha inhliziyo. Ngokubeka ama-electrode amaningi ezindaweni ezithile zomzimba, irekhoda inhliziyo's ugesi ovela kuma-engeli ahlukahlukene, ukuhlinzeka odokotela ngolwazi oluningiliziwe lwe-cardiac electrophysiological olusiza ukuxilongwa okunembe kakhudlwana kanye nokuhlolwa kwezifo zenhliziyo.

Izintambo ze-ECG ezihamba phambili ezingu-10 noma ezingu-12 zihlanganisa okulandelayo:

(1)Ukuhola Kwemilenze Ejwayelekile (Ihola I, II, III):

Le mikhondo ikala umehluko ongaba khona phakathi kwezitho ngokusebenzisa ama-electrode abekwe engalweni yesokudla (RA), engalweni yesokunxele (LA), nomlenze wesobunxele (LL). Zibonisa inhliziyo's umsebenzi kagesi endizeni engaphambili.

(2)I-Augmented Unipolar Limb Leads (aVR, aVL, aVF):

Lezi ziqondiso zitholwa kusetshenziswa ukucushwa kwe-electrode okukhethekile futhi kunikeze imibono eyengeziwe yokuqondisa yenhliziyo's umsebenzi kagesi endizeni engaphambili:

•  I-aVR: Ibuka inhliziyo ukusuka ehlombe elingakwesokudla, igxile engxenyeni engenhla yenhliziyo engakwesokudla.
•  i-aVL: Ibuka inhliziyo ukusuka ehlombe lesokunxele, igxile engxenyeni engenhla kwesokunxele senhliziyo.
•  I-aVF: Ibuka inhliziyo kusukela onyaweni, igxile endaweni engaphansi (ephansi) yenhliziyo.

(3)I-Precordial (Isifuba) ihola

•  Ihola V1-I-V6 ibekwe ezindaweni ezithile esifubeni futhi irekhoda umsebenzi kagesi endizeni evundlile:
•  V1-I-V2: Bonisa umsebenzi ovela ku-ventricle efanele kanye ne-interventricular septum.
•  V3-I-V4: Bonisa umsebenzi ovela odongeni lwangaphambili lwe-ventricle kwesokunxele, ne-V4 etholakala eduze kwe-apex.
•  V5-I-V6: Bonisa umsebenzi ovela odongeni olungemuva lwe-ventricle yesokunxele.

(4)Isifuba Sesokudla siyahola

I-Leads V3R, V4R, ne-V5R ibekwe esifubeni sokudla, ukwenza isibuko kuholela ku-V3 kuya ku-V5 kwesokunxele. Lokhu kuhola kuhlola ngokuqondile ukusebenza kwe-ventricular efanele kanye nokungajwayelekile, njenge-myocardial infarction ehlangothini lwesokudla noma i-hypertrophy.

Ukuhlukaniswa ngezinhlobo ze-Electrode kusixhumi Sesiguli

1.Izintambo zokuhola ze-ECG zohlobo lwe-Snap

Izintambo eziholayo zifaka idizayini enamacala amabili. Omaka abanemibala enziwe ngomjovo, okuqinisekisa ukuhlonza okucacile okungeke kufiphele noma kuxege ngokuhamba kwesikhathi. Idizayini ye-mesh engazweli uthuli inikeza indawo yebhafa enwetshiwe yokuguquguquka kwekhebula, ithuthukisa ukuqina, ukuhlanzeka kalula, nokumelana nokugoba.

 2.I-Round Snap ECG LeadWires

• Inkinobho Eseceleni kanye Nedizayini Yokuxhumanisa Okubonakalayo:Ihlinzeka odokotela ngokukhiya okuvikelekile kanye nendlela yokuqinisekisa ebonakalayo, evumela ukuxhumana komthofu okushesha futhi okuthembekile;Kufakazelwe ngokomtholampilo ukunciphisa ingozi yama-alamu angamanga abangelwa ukunqanyulwa komthofu.
• Idizayini yekhebula yeribhoni ecwecwayo:Iqeda ukuxhunyaniswa kwekhebula, ukonga isikhathi nokuthuthukisa ukusebenza kahle komsebenzi; Ivumela ukuhlukaniswa komthofu okwenziwe ngokwezifiso okusekelwe kusayizi womzimba wesiguli ukuze ilingane nokunethezeka kangcono.
• Izintambo Zokuhola Ezikabili Ezivikelwe Ngokugcwele:Inikeza ukuvikeleka okuphezulu ekuphazamisekeni kwe-electromagnetic, okuyenza ilungele izindawo ezinemishini kagesi ebanzi. 

3.Grabber-Type ECG Lead Izintambo

Iizintambo zokuhola ze-ECG zohlobo lwe-grabberakhiqizwa kusetshenziswa inqubo edidiyelwe yokubumba umjovo, okwenza kube lula ukuwahlanza, angangeni manzi, futhi amelane namaconsi. Lo mklamo uvikela ngempumelelo ama-electrode, uqinisekisa ukuqhutshwa kwe-conductivity enhle kakhulu kanye nokutholwa kwesignali okuzinzile. Izintambo eziholayo zibhangqwe nezintambo ezinombala ezihambisana namalebula e-electrode, zinikeza ukubonakala okuphezulu nokusebenza komsebenzisi.

4.4.0 Ubhanana kanye ne-3.0 Pin ECG Lead Wire

I-The4.0 banana kanye ne-3.0 pin ECG lead wireshave imininingwane yesixhumi esimisiwe esiqinisekisa ukuhambisana nokudluliswa kwesignali okuthembekile. Zifanele uhla olubanzi lwezinhlelo zokusebenza zomtholampilo, okuhlanganisa izinqubo zokuxilonga kanye nokuqapha kwe-ECG okunamandla, okuhlinzeka ngokusekelwa okuthembekile kokuqoqwa kwedatha okunembile.

Kufanele zibekwe kanjani izintambo zokuhola ze-ECG ngendlela efanele?

Izintambo zokuhola ze-ECG kufanele zibekwe ngokuvumelana nezimpawu zendawo ezijwayelekile ze-anatomical. Ukusiza ngokubeka okulungile, izintambo ngokuvamile zinekhodi yombala futhi zilebulwe ngokucacile, okwenza kube lula ukukhomba nokuhlukanisa umthofu ngamunye.
