Izintambo zomthofu ze-ECG ziyizingxenye ezibalulekile ekuqapheni isiguli, okuvumela ukutholwa okunembile kwedatha ye-electrocardiogram (ECG). Nasi isingeniso esilula sezintambo zomthofu ze-ECG ngokusekelwe ekuhlukanisweni komkhiqizo ukuze sikusize uziqonde kangcono.

Ukuhlukaniswa Kwezintambo Ze-ECG Nezintambo Zomthofu Ngokwesakhiwo Somkhiqizo

1.Amakhebula e-ECG ahlanganisiwe

IAmakhebula e-ECG ahlanganisiweyamukela umklamo omusha ohlanganisa kakhulu ama-electrode namakhebula, okwenza kube nokuxhumana okuqondile kusukela ekugcineni kwesiguli kuya kusikrini ngaphandle kwezingxenye eziphakathi. Lesi sakhiwo esilula asigcini nje ngokwenza kube lula ukwakheka kodwa futhi sisusa izixhumi eziningi ezivame ukutholakala ezinhlelweni zendabuko zohlobo oluhlukanisiwe. Ngenxa yalokho, kunciphisa kakhulu ingozi yokwehluleka ngenxa yokuxhumana okungafanele noma umonakalo wokuphawula, okunikeza ikhambi elizinzile nelithembekile lokuqapha isiguli. Umdwebo olandelayo ubonisa ukusetshenziswa kwamakhebula e-ECG ahlanganisiwe njengereferensi yakho.

2.Izintambo Zesiqu Se-ECG

IIzintambo ze-ECG Trunkiyisici esibalulekile sohlelo lokuqapha lwe-ECG, oluqukethe izingxenye ezintathu: isixhumi semishini, ikhebula lesiqu, kanye nesixhumi se-yoke.

3.Izintambo Zokuhola ze-ECG

Izintambo ze-lead ze-ECGzisetshenziswa kanye nezintambo ze-trunk ze-ECG. Kulo mklamo ohlukanisiwe, izintambo eziholayo kuphela ezidinga ukushintshwa uma zonakele, kuyilapho ikhebula le-trunk lihlala lisebenziseka, okuholela ezindleleni zokulungisa eziphansi uma kuqhathaniswa nezintambo ze-ECG ezihlanganisiwe. Ngaphezu kwalokho, izintambo ze-trunk ze-ECG azixhunywa futhi azixhunywa njalo, okungandisa kakhulu impilo yazo yesevisi.

Izintambo ze-ECG kanye nezintambo ze-Lead Ukuhlukaniswa ngenani le-Lead

• Amakhebula e-ECG angu-3-Lead

Ngokwesakhiwo,Izintambo ze-ECG ezi-3-leadIqukethe izintambo ezintathu zomthofu, ngayinye ixhunywe ku-electrode ethile. Lawa ma-electrode abekwa ezingxenyeni ezahlukene zomzimba wesiguli ukuze kutholakale izimpawu ze-bioelectric. Emtholampilo, izindawo ezivamile zokubeka ama-electrode zifaka ingalo yesokudla (RA), ingalo yesobunxele (LA), kanye nomlenze wesobunxele (LL). Lokhu kulungiselelwa kwenza kube lula ukuqopha inhliziyo'umsebenzi kagesi ovela ezinhlangothini eziningi, ohlinzeka ngemininingwane ebalulekile yokuxilongwa okunembile kwezokwelapha.

•  Amakhebula e-ECG angu-5-Lead

Uma kuqhathaniswa nezintambo ze-ECG ezine-lead ezintathu,Izintambo ze-ECG ezinama-lead angu-5ukucushwa kuhlinzeka ngedatha kagesi yenhliziyo ephelele kakhulu ngokuthwebula izimpawu ezivela ezindaweni ezengeziwe zomzimba. Ama-electrode avame ukufakwa ku-RA (ingalo yesokudla), i-LA (ingalo yesobunxele), i-RL (umlenze wesokudla), i-LL (umlenze wesobunxele), kanye ne-V (umthofu wangaphambi kokuqoshwa/wesifuba), okuvumela ukuqapha kwenhliziyo okunezinhlangothi eziningi. Lokhu kusethwa okuthuthukisiwe kunikeza odokotela ukuqonda okunembile nokubanzi kwenhliziyo.'isimo se-electrophysiological, okusekela ukuxilongwa okunembe kakhudlwana kanye namasu okwelapha aqondene nomuntu ngamunye.

•  Amakhebula e-ECG angu-10-Lead noma angu-12-Lead

IIkhebula le-ECG eliyi-10-Lead / 12-Leadkuyindlela ephelele yokuqapha inhliziyo. Ngokubeka ama-electrode amaningi ezindaweni ezithile zomzimba, iqopha inhliziyo'umsebenzi kagesi ovela ezinhlangothini ezahlukene, ohlinzeka odokotela ngolwazi oluningiliziwe lwe-electrophysiological yenhliziyo olusiza ekuxilongweni nasekuhlolweni kwezifo zenhliziyo okunembe kakhudlwana.

Izintambo ze-ECG ezinama-lead angu-10 noma angu-12 zifaka okulandelayo:

(1)Ama-Lead Ajwayelekile Emilenze (Ama-Lead I, II, III):

Lezi zinduku zilinganisa umehluko ongaba khona phakathi kwamalungu ngokusebenzisa ama-electrode abekwe engalweni yesokudla (RA), engalweni yesobunxele (LA), kanye nomlenze wesobunxele (LL). Zibonakalisa inhliziyo'umsebenzi kagesi endaweni engaphambili.

(2)Ama-Unipolar Limb Leads angeziwe (aVR, aVL, aVF):

Lezi zikhonkwane zitholakala kusetshenziswa ukucushwa kwe-electrode ethile futhi zinikeza imibono eyengeziwe yokuqondisa kwenhliziyo'umsebenzi kagesi endaweni engaphambili:

•  i-aVR: Ibuka inhliziyo isehlombe langakwesokudla, igxile engxenyeni ephezulu yesokudla yenhliziyo.
•  i-aVL: Ibuka inhliziyo isehlombe lesobunxele, igxile engxenyeni ephezulu kwesobunxele yenhliziyo.
•  aVF: Ubheka inhliziyo esenyaweni, egxile esifundeni esingaphansi (esiphansi) senhliziyo.

(3)Ama-Prerecordial (Isifuba) Ama-Lead

•  Ama-Lead V1–Ama-V6 abekwa ezindaweni ezithile esifubeni futhi aqopha umsebenzi kagesi endizeni evundlile:
•  V1–V2: Bonisa umsebenzi ovela ku-ventricle yesokudla kanye ne-septum ephakathi kwe-ventricular.
•  V3–V4: Bonisa umsebenzi ovela odongeni olungaphambili lwe-ventricle yesobunxele, i-V4 iseduze ne-peak.
•  V5–V6: Bonisa umsebenzi ovela odongeni oluseceleni lwe-ventricle yesobunxele.

(4)Ama-Leads Esifuba Sangakwesokudla

Ama-lead V3R, V4R, kanye ne-V5R abekwe esifubeni sokudla, ukulinganisa ama-lead V3 kuya ku-V5 ngakwesobunxele. Lawa ma-lead ahlola ngqo ukusebenza kwe-ventricle yesokudla kanye nokukhubazeka, njenge-myocardial infarction noma i-hypertrophy.

Ukuhlukaniswa ngezinhlobo ze-Electrode ku-Patient Connector

1.Izintambo Zokuhola Ze-ECG Zohlobo Lwe-Snap

Izintambo zomthofu zinomklamo we-sheath onamahlangothi amabili. Amamaki anemibala abunjwe ngomjovo, okuqinisekisa ukuhlonza okucacile okungeke kuphele noma kuqhekeke ngokuhamba kwesikhathi. Umklamo womsila we-mesh omelana nothuli unikeza indawo ende yokubopha ikhebula, ukuqinisa ukuqina, ukuhlanzwa kalula, kanye nokumelana nokugoba.

 2. Ama-Round Snap ECG LeadWires

• Inkinobho Eseceleni kanye Nomklamo Wokuxhumeka Okubonakalayo:Ihlinzeka odokotela ngendlela evikelekile yokukhiya kanye nokuqinisekisa okubonakalayo, okuvumela ukuxhumana okusheshayo nokuthembekile kwe-lead;Kufakazelwe ngokwezokwelapha ukuthi kunciphisa ingozi yezixwayiso ezingamanga ezibangelwa ukunqanyulwa komthofu.
• Umklamo Wekhebula Leribhoni Elikwazi Ukuhlubuka:Kuqeda ukuxhunywa kwezintambo, konga isikhathi futhi kuthuthukise ukusebenza kahle komsebenzi; Kuvumela ukuhlukaniswa komthofu okwenziwe ngokwezifiso ngokusekelwe kusayizi womzimba wesiguli ukuze kulingane kahle futhi kududuzeke kangcono.
• Izintambo Zokuhola Ezivikelwe Ngokugcwele Ezinezingqimba Ezimbili:Inikeza isivikelo esiphezulu ekuphazamisekeni kwe-electromagnetic, okwenza kube kuhle kakhulu ezindaweni ezinemishini kagesi eminingi. 

Izintambo Zokuhola ze-ECG Zohlobo lwe-Grabber 3.

Iizintambo ze-lead ze-ECG zohlobo lwe-grabberakhiqizwa kusetshenziswa inqubo yokubumba ehlanganisiwe yokujova, okwenza kube lula ukuwahlanza, angangenwa manzi, futhi amelane nokuwa. Lo mklamo uvikela ngempumelelo ama-electrode, uqinisekisa ukuhanjiswa kahle kakhulu kanye nokutholwa kwesignali okuzinzile. Izintambo zomthofu zihambisana nezintambo ezinemibala ehambisana namalebula e-electrode, okunikeza ukubonakala okuphezulu kanye nokusebenza okulula ukukusebenzisa.

Izintambo ze-Lead ze-ECG ze-4.4.0 Banana kanye ne-3.0 Pin

Izintambo ze-lead ze-ECG zebhanana ezingu-4.0 kanye ne-3.0 pin zinezincazelo ezijwayelekile zokuxhuma eziqinisekisa ukuhambisana kanye nokudluliselwa kwesignali okuthembekile. Zifanelekela izinhlelo zokusebenza eziningi zezokwelapha, kufaka phakathi izinqubo zokuxilonga kanye nokuqapha kwe-ECG okunamandla, okunikeza ukwesekwa okuthembekile kokuqoqwa kwedatha okunembile.

Izintambo ze-ECG lead kufanele zibekwe kanjani ngendlela efanele?

Izintambo zomthofu ze-ECG kufanele zibekwe ngokwezimpawu ezijwayelekile zomzimba. Ukuze kusizwe ekubekweni okufanele, izintambo zivame ukufakwa imibala futhi zibhalwe ngokucacile, okwenza kube lula ukubona nokuhlukanisa intambo ngayinye.
