ULWAZI LWE-ODAKungani Kufanele Sisebenzise Ama-Electrode e-Offset ECG?
Lapho iziguli zithola ukutholwa kwe-holter ECG kanye ne-telemetric ECG monitor, ngenxa yokuvela kokungqubuzana kwezingubo, amandla adonsela phansi, kanye nokudonsa, kubangela ukuphazamiseka okwenziwayo [1] esignalini ye-ECG, okwenza kube nzima kakhulu kodokotela ukuxilonga.
Ukusebenzisa ama-electrode e-ECG angaphandle kunganciphisa kakhulu ukuphazamiseka kwezinto ezidaliwe futhi kuthuthukise ikhwalithi yokutholwa kwesignali ye-ECG eluhlaza, ngaleyo ndlela kuncishiswe izinga lokuxilongwa kwesifo senhliziyo okungafanele ekuhlolweni kwe-holter kanye nama-alamu angamanga ekuqapheni kwe-ECG ye-telemetric ngodokotela[2].
Umdwebo Wesakhiwo Se-Electrode Ye-Offset ECG
Izinzuzo Zomkhiqizo
Okuthembekile:Umklamo wokufaka i-offset, indawo yokudonsa i-buffer esebenza kahle, uvimbela kakhulu ukuphazamiseka kwezinto ezinyakazayo, uqinisekisa ukuthi isignali izinzile futhi ithembekile.
Izinzile：Inqubo yokuphrinta ye-Ag/AgCL enelungelo lobunikazi, esheshayo ngokutholwa kokumelana, iqinisekisa ukuzinza kokudluliswa kwedatha isikhathi eside.
Okukhululekile:Ukuthamba okuphelele: isisekelo esingalukiwe sezokwelapha, esithambile futhi esiphefumulayo, esiwusizo kakhulu ekukhipheni umjuluko futhi sithuthukise izinga lokududuzeka kwesiguli.
Ukuhlolwa Kokuqhathanisa: I-Offset ECG Electrode kanye ne-Center ECG Electrode
Ukuhlolwa Kokuthepha:
| I-Electrode ye-ECG Yesikhungo | I-Electrode ye-ECG ye-Offset |
 |  |
| Uma isiguli silele phansi, futhi sixhunywe ku-leadwire ye-ECG, senza ingcindezi ku-conductive hydrogel, khona-ke kuba noshintsho ekumelaneni kokuthintana eduze kwe-conductive hydrogel. | Uma isiguli silele phansi, futhi sixhunywe ku-leadwire ye-ECG, asicindezeli i-hydrogel eqhubayo, engaba nomthelela omkhulu ekuphikisweni kokuxhumana okuzungeze i-hydrogel eqhubayo. |
| Ukusebenzisa i-simulator ngokwahlukana thinta ukuxhumana kwama-electrode e-offset e-ECG kanye nama-electrode e-Center fitting ECG njalo ngemizuzwana emi-4, kanti ama-ECG atholakalayo ayemi kanje: | |
 | |
| Imiphumela:Isignali ye-ECG ishintshe kakhulu, i-baseline drift yafika ku-7000uV. | Imiphumela:Isignali ye-ECG ayithinteki, iqhubeka nokukhiqiza idatha ye-ECG ethembekile. |
Ukuhlolwa Kokudonsa

 |  |
| Uma intambo ye-lead ye-ECG idonswa, i-force Fa1 isebenza ku-skin-gel interface kanye ne-AgCLelectrode-gel interface, lapho i-AgCL sensor kanye ne-conductive hydrogel zisuswa yi-pull, zombili ziphazamisa ukuxhumana kukagesi nesikhumba, bese zikhiqiza ama-artifacts esignali ye-ECG. | Uma udonsa ucingo lwe-ECG, i-force Fa2 isebenza esibonakalayo sejeli esinamathelayo esikhumbeni, ayinyamalali esifundeni se-hydrogel esiqhubayo, ngakho-ke ikhiqiza izinto ezimbalwa ezikhiqizwayo. |
Ngasohlangothini oluqondile lwendiza yesenzwa yesikhumba, ngamandla ka-F=1N, ucingo lwe-lead lwe-ECG oluku-electrode ephakathi kanye ne-electrode engavamile kwadonswa ngokwehlukana cishe njalo ngemizuzwana emi-3, kanti ama-ECG atholakele ayelandelayo: | |
| Izimpawu ze-ECG ezikhiqizwe yi-electrode ezimbili zazibukeka zifana ncamashi ngaphambi kokuba kudonswe izintambo zomthofu. | |
| Imiphumela:Ngemva kokudonsa kwesibili kwe-ECGleadwire, isignali ye-ECG ibonise ngokushesha ukushelela kwesisekelo kufikela ku-7000uV. Ukushelela kwesisekelo okungenzeka kufikela ku-±1000uV futhi ama-boe awakwazi ukubuyisa ngokuphelele ukungazinzi kwesignali. | Imiphumela:Ngemva kokudonsa kwesibili kwe-ECGleadwire, isignali ye-ECG ibonise ukwehla kwesikhashana okungu-1000uV, kodwa isignali yabuya ngokushesha phakathi nemizuzwana engu-0.1. |

QAPHELA:
2. Iwebhusayithi ingabhekisela ezinkampanini zangaphandle kanye nemikhiqizo engahlobene nathi nganoma iyiphi indlela. Izithombe zomkhiqizo zenzelwe izinjongo zokubonisa kuphela futhi zingase zihluke ezintweni zangempela (isb., umehluko ekubukekeni kwesixhumi noma umbala). Uma kwenzeka noma yikuphi ukungafani, umkhiqizo wangempela uzonqoba.
