Ⅰ. Kuumbwa Kwechigadzirwa
Mamiriro ekutanga: chikamu chekuisa, chikamu cheamplifier, dunhu rekutonga, chikamu chekuratidzira, chikamu chekurekodha, chikamu chemagetsi, chikamu chekukurukurirana
Chikamu chekurekodha (musoro wekudhinda, ndiro yekudhinda, bhini rebepa, nezvimwewo)
Ratidza chikamu (rinoratidza bhodhi, LCD)
Chikamu chekupa magetsi (adapter, adapter board, bhatiri)
Kukurukurirana chikamu (usb interface, UART interface, nezvimwewo)
Input/amplification chikamu (lead wire interface, channel board)
Kudzora dunhu (main board, kiyi bhodhi, nezvimwewo)
Ⅱ. Annex Muumbirwo
Ⅲ. Basics
Electrocardiogram (ECG) igirafu (curve) inorekodha kubva pamusoro pemuviri shanduko yemagetsi anogadzirwa nemoyo panguva yega yega yemoyo kutenderera.
Electrocardiogram inogona kuratidza bioelectric inogona kuchinja panguva yechizvarwa, conduction uye kudzoreredza kwekunakidzwa kwemoyo.
Vanachiremba vanoongorora uye kuona kushanda kwemoyo uye hosha dzakawanda dzemoyo kubva kukuchinja kwebioelectrical yemoyo.
Ikozvino yepasi rose ECG ndiyo inotungamira inotungamira, iyo inoumbwa negumi nembiri inotungamira, uye saka iyo general ECG icharatidza gumi nemaviri mitsara yemafungu. Kuburikidza nekutora zviratidzo kubva kune gumi nembiri-inotungamira ECG, zvinokwanisika kuburitsa zvisina kunanga nzvimbo yekubva uye kusaenzana kwechirwere chemoyo. Semuenzaniso, zvirwere zvinowanzoitika ndeye myocardial infarction uye myocardial ischemia. (Cherechedza: ECG lead inoreva kuiswa kwemaelectrodes pamusoro pemuviri wemunhu uye kubatana kwemagetsi kune amplifier kana uchitsvaga ECG; lead imhando yekubatanidza! Electrode inzira inofambisa. Maelectrode eECG akakamurwa kuita magetsi emakumbo (4) uye chipfuva.
● Chii chinonzi 12-lead?
Iyo 12 inotungamira yaisanganisira 6 mitezo inotungamira (I, II, III, aVR, aVL, uye aVF) uye 6 chest inotungamira (V1 kusvika V6). Mitinha inotungamira yaisanganisira yakajairwa bipolar lead (I, II, uye III) uye yakamanikidzwa inotungamira (aVR, aVL, uye aVF). Bipolar lead inopihwa mazita ekurekodha musiyano wevoltage pakati pematanho maviri
● Clinical kukosha uye kushandiswa
- Clinical kukosha: rekodha basa remagetsi remoyo wemunhu; kubatsira kuongorora arrhythmia, myocardial ischemia, myocardial infarction, myocarditis, cardiomyopathy, kusakwana kweropa reropa, pericarditis, nezvimwewo; kubatsira kuona mhedzisiro yezvinodhaka kana kusagadzikana kwe electrolyte pamwoyo; kubatsira kuona mamiriro ezvakagadzirwa mwoyo pacing.
- Inoshandiswa zvakanyanya: kuongororwa kwemuviri, kuvhiyiwa, anesthesia, kutarisa kwemishonga, mitambo, aerospace uye kumwe kutarisa kwemoyo uye kununura varwere vanorwara zvakanyanya.
● Ndezvipi zvinotungamirira uye nzira yemuchina weECG?
ECG muchina une gumi nembiri anotungamira: a specialized ECG muchina ane huwandu hwegumi nemaviri ekutungamira ekutungamira mumuviri, ine 3 bipolar lemb lead, 3 unipolar pressurized lemb lead, uye 6 chest inotungamira. Zvose zvinotungamira gumi nemaviri.
Naizvozvo, gumi nemaviri anotungamira hachisi chinhu chakanaka cheimwe EKG muchina, asi chakanyanya kukosha chimiro!
Saka ndeipi pfungwa yematanho gumi nemaviri mumushini weECG?
Iyo 12-lead, sezvambotaurwa, inozviratidza muchimiro chegumi nembiri-channel waveform, uyezve isu tinofanirwa kudhinda iyo yakanyorwa waveform data, panguva iyo, mashoma ma parameter akakosha: waveform kurongeka, kujeka, uye kumhanya kweprintout.
Kana bepa rekurekodha rakakura, kurongeka kwakaringana, ipapo 12 inotungamira yedata inogona kudhindwa panguva imwe chete, panguva ino, ichakurumidza kupfuura imwe chiteshi, chiteshi chetatu, nhanho nhanhatu, zvakananga 2 kusvika ku12 nguva.
Kureva kuti, chiteshi chimwe chete chingori chimwe chete waveform kudhinda, matatu chiteshi idhinda matatu waveforms, zvakafanana, nhanhatu nzira dzichadhinda matanhatu mafungu, gumi nembiri-chiteshi muchina inodhinda gumi nembiri waveform.
Cheki imwe chete, imwe-chani muchina kudhinda kagumi nembiri kudhinda ese gumi nemaviri-channel waveform, ukuwo gumi nemaviri-channel muchina unozodhinda ese gumi nemaviri-channel waveform yakadhindwa.
Iyo iri nyore uye yakananga nzira yekutarisa iyi ndeyekutarisa nzvimbo yeprint cartridge; cardiometers dzakasiyana dzine nhamba dzakasiyana dzemigwagwa dzine hupamhi hwakasiyana hwemapepa ekudhinda.

Ⅶ. Common ECG terminology
Kutungamira: Iyo yedunhu yekubatanidza nzira yekurekodha ECG.
Chiteshi: inoenderana nebasa rekudhinda reECG muchina, kana uchidhinda, vangani vanotungamira vanogona kunyorwa panguva imwe chete.
Tsanangudzo: Ongororo yemhedzisiro yeECG yekutora kuti ipe diagnostic reference.
Kurekodha Mode: Kudhinda maitiro (eg 3ch ECG printing format 1ch + R, 3ch, 3ch +)
Maitiro Okushanda: Manual, otomatiki, kuongorora, kuchengetedza, etc.
Sampling Rate: Nhamba yemasampuli pasekondi imwe neimwe yakatorwa kubva muchiratidzo chinoramba ichigadzira chiratidzo chakajeka, chinoratidzwa muHertz (Hz).
Kusefa: Iko kushanda kwekusefa kwakasiyana bhendi frequency kubva pachiratidzo kudzvanya nekudzivirira kukanganisa (AC kusefa, EMG kusefa, kudhiraivha kusefa).
Sensitivity: Kukwidziridzwa kwechiratidzo cheECG nemuchina.
Pepa Kumhanya: Iyo yekumhanyisa bepa rekodha.
Pulse Pace Identification: Inoziva pacing pulse zviratidzo.
