I-electrocardiogram monitor iyithuluzi elibalulekile lokunakekelwa kwezempilo okwamanje.Noma ngabe iyunithi yabagula kakhulu noma iwadi evamile, ngokuvamile ifakwe lolu hlobo lwemishini.
Inhloso eyinhloko yokuqapha kwe-ECG ukuthola nokubonisa isignali ye-ECG ekhiqizwa ukushaya kwenhliziyo yesiguli.Amasekhethi angaphakathi omshini wokuqapha we-ECG awavamile ukonakala.Iningi lezinkinga izintambo eziholayo ze-ECG, ama-electrode e-ECG kanye nezilungiselelo.
1. Iphutha lokusetha lemonitha ye-ECG:Ngokuvamile, izintambo eziholayo zemonitha ye-ECG zinemikhondo emi-3 nemikhondo emi-5.Uma ukulungiselelwa kungalungile, i-waveform ayikwazi ukuboniswa noma i-waveform ayilungile.Ngakho-ke, lapho ukuqapha kwe-ECG kungenasignali ye-ECG noma i-waveform inganembile, qala uhlole ukuthi ukulungiselelwa komshini kulungile yini.Ngaphezu kwalokho, ama-monitor amaningi anemisebenzi yokuhlunga yedijithali engahlunga ukuphazamiseka kwefrikhwensi yamandla.Iningi labaqaphi be-ECG banamaza okuhlunga amabili, i-50 kanye ne-60HZ, ukuze umshini usetshenziswe ezifundeni ezahlukene.
2. I-ECG lead wire iphukile:Indlela eqondile kakhulu yokukala ukuthi intambo yokuhola ye-ECG iphukile ukusebenzisa i-multimeter.Ngokuvamile i-ECG qapha ayikwazi ukubonisa i-waveform ye-ECG inqobo nje uma enye yezintambo zenhliziyo iphukile.Ithuluzi lingacindezela ukuphela kwe-electrode ye-ECG okuholela emunweni.Uma i-monitor ingabonisa i-waveform yomsindo, khona-ke ukuhola kwe-ECG kuxhunyiwe.Uma isignali ye-ECG ingatholakali, ukuhola kwe-ECG cishe kuphukile.
3.inkinga yeshidi le-ECG electrode:Ikhwalithi ye-electrode ye-ECG ayilungile, futhi isikhundla esingalungile sizokwenza i-electrocardiograph ihluleke ukukala isignali ye-ECG noma isignali elinganisiwe ayilungile.Uma kungekho nkinga ngezilungiselelo zokuqapha kanye nocingo oluholayo lwe-ECG, kuyinkinga ye-electrode ye-ECG.Abahlengikazi abaningi namuhla banamakhono ampofu, futhi ngokuvamile abakwazi ukunamathela ngisho ne-electrode ye-ECG.Indlela efanele yokufaka ama-electrode e-ECG ukusebenzisa i-sandpaper encane kuma-electrode e-ECG ukuze uhlikihle kahle i-stratum corneum esikhumbeni sesiguli.I-saline encane.(Ama-electrode e-ECG angenisiwe ngokuvamile awanayo i-sandpaper, futhi angaxhunywa ngokuqondile esikhumbeni sesiguli ukuze athole i-waveform enhle, kodwa intengo iphakeme kakhulu. Izinga le-electrode ye-ECG yasekhaya ingase ingabi yinhle kangako, ngakho-ke thola ucezu i-sandpaper ukumelana nayo) Ngaphezu kwalokho, ukuxhunywa okungekuhle komhlabathi kwemonitha nakho kuzodala ukuphazamiseka okukhulu, ngakho imitha yendawo yonke kufanele isetshenziselwe ukuhlola i-voltage yocingo oluphansi ukuze kuqinisekiswe ukuthi ucingo oluphansi luvamile.
