ODA ULWAZIKungani Kufanele Sisebenzise I-Offset ECG Electrodes?
Lapho iziguli zithola i-holter ECG kanye nokuqapha kwe-ECG ye-telemetric, ngenxa yokuvela kokungqubuzana kwezingubo, amandla adonsela phansi alele, kanye nokudonsa, kubangela ukuphazamiseka okwenziwayo[1] kusignali ye-ECG, okwenza kube nzima kakhulu ngodokotela ukuxilonga.
Ukusebenzisa ama-electrode e-ECG e-offset kunganciphisa kakhulu ukuphazamiseka kwe-artifact futhi kuthuthukise ikhwalithi yokutholwa kwesignali ye-ECG eluhlaza, ngaleyo ndlela kunciphise izinga lokuxilongwa okuphuthelwe kwesifo senhliziyo ekuhlolweni kwe-holter nama-alamu angamanga ekuqaphelweni kwe-ECG ye-telemetric ngodokotela[2].

Izinzuzo Zomkhiqizo
Okuthembekile:Idizayini yokulinganisa i-offset, indawo esebenzayo yokudonsa ibhafa, ivimbela kakhulu ukuphazamiseka kwezinto ezinyakazayo, iqinisekisa ukuthi isignali izinzile futhi ithembekile.
Izinzile:Inqubo yokuphrinta ye-Ag/AgCL enelungelo lobunikazi, ngokushesha ngokutholwa kokumelana, iqinisekisa ukuzinza kokudluliswa kwedatha kwesikhathi eside.
Ukhululekile:Ukuthamba sekukonke: ukwesekwa kwezokwelapha okungalukiwe, okuthambile futhi okuphefumulayo, okuwusizo kakhulu ukuhwamuka komjuluko nokuthuthukisa izinga lokunethezeka kwesiguli.
Ukuhlolwa kokuqhathanisa: I-Offset ECG Electrode kanye ne-Center ECG Electrode
Ukuthepha Ukuhlola:

| Lapho isiguli silele sibheke phansi, futhi sixhunywe kucingo oluholayo lwe-ECG, senza ingcindezi ku-hydrogel eqhubayo, khona-ke kuba noshintsho ekuqineni kokuthintana eduze kwe-conductive hydrogel. | Lapho isiguli esilele sibheke phansi, futhi sixhunywe kucingo oluholayo lwe-ECG, lungafaki ingcindezi ku-conductive hydrogel, enomthelela omncane ekuphikisweni kokuxhumana okuzungeze i-conductive hydrogel. |
| Ukusebenzisa isifanisi thinta ngokuhlukile ekuxhumekeni kwama-electrode e-ECG kanye nama-electrode e-ECG afaka Isikhungo njalo ngemizuzwana emi-4, futhi i-ECG etholakele ibe kanje: | |
 | |
| Imiphumela:Isignali ye-ECG yashintsha kakhulu, isisekelo sokukhukhuleka sifika ku-7000uV. | Imiphumela:Isignali ye-ECG ayithinteki, ngokuqhubekayo ukukhiqiza idatha ye-ECG ethembekile. |
Ukudonsa Ukuhlola

| Lapho i-leadwire ye-ECG idonswa, amandla e-Fa1 asebenza ku-skin-gelinterface kanye nesixhumi esibonakalayo se-AgCLelectrode-gel, lapho inzwa ye-AgCL kanye ne-conductive hydrogel kususwa ukudonsa, kokubili kuphazamisa ukuthintana kukagesi nesikhumba, bese kukhiqiza ama-artifacts wesignali ye-ECG. | Lapho udonsa intambo yocingo ye-ECG, amandla i-Fa2 asebenza ku-theskin-adhesive gel interface, ayishabalali endaweni ye-conductive hydrogel, ngakho-ke kukhiqizwa izinto zobuciko ezimbalwa. |
Ehlangothini elibheke endizeni yenzwa yesikhumba, ngamandla e-F=1N, i-leadwire ye-ECG ku-electrode emaphakathi kanye ne-eccentric electrode yadonswa ngokwehlukana cishe njalo emizuzwaneni emi-3, kanti ama-ECG atholakele abe kanje: | |
| Amasignali e-ECG akhiqizwa ama-electrode amabili ayebukeka efana ncamashi ngaphambi kokuba izintambo zokuhola zidonswe. | |
| Imiphumela:Ngemva kokudonsa kwesibili kwe-ECGleadwire, isignali ye-ECG yabonisa ngokushesha isisekelo sokukhukhuleka sifika ku-7000uV. Isisekelo esingaba khona sikhukhuleka size sifike ku-±1000uV futhi ama-boes awakutholi ngokugcwele ukungazinzi kwesignali. | Imiphumela:Ngemva kokudonsa kwesibili kwe-ECGleadwire, isignali ye-ECG ibonise ukwehla kwesikhashana okungu-1000uV, kodwa isignali yalulama ngokushesha phakathi nemizuzwana engu-0.1. |

QAPHELA:
2. Iwebhusayithi ingase ibhekisele ezinkampanini zezinkampani zangaphandle kanye nemikhiqizo engaxhumene nathi nganoma iyiphi indlela. Izithombe zomkhiqizo ezezinjongo zemifanekiso kuphela futhi zingahluka ezintweni zangempela (isb, umehluko ekubukekeni kwesixhumi noma umbala). Uma kwenzeka noma yikuphi ukungqubuzana, umkhiqizo wangempela uzosebenza.
