ECG umatshini (electrocardiograph): iintlobo, imigaqo yokusebenza

Electrocardiography - indlela zophando izihlunu zentliziyo. Ngoncedo yunithi ECG oza ukulungisa eyenziwe zombane kunye ngokuphambili Iziphumo ukuvelisa ngohlobo imifanekiso graphic kwiphepha thermal (kwiimeko ezininzi). Eyokuqala data kumatshini ECG abhalwe kwi umboniso, ngoko maza kukhona-inki. Ukuba ifowuni yi computer ngokupheleleyo, idata lugcinwe kwinkumbulo yekhomputha.

ukusebenzisa electrocardiographs

Inkqubo electrocardiography lwenziwa kunye neenjongo zilandelayo:

• ukufumanisa frequency kunye amaxesha izishunqulelo kwemisipha intliziyo;
• ukuba ufuna ukufumanisa ubukho kwemithambo okanye ukuhlaselwa yintliziyo;
• ukuba ufuna ukuqinisekisa okanye ukuphika kukho intswelo electrolyte;
• Ubukho update ukuvimba intliziyo;
• Uvavanyo iimfuno ngexesha kwetyala kunye umthwalo;
• Ukuba ufuna ukucacisa iimpawu yokwakheka kunye nokomzimba yentliziyo (umzekelo, ventricular ekhohlo hypertrophy) ;
• ukuba ufuna ukuqinisekisa okanye ukuphika uphuhliso Embolism pulmonary;
• ukuhlolwa lokuthintela nokuxilonga labemi ngethuba.

izixhobo zale mihla

Nokuba 20-30 kwiminyaka eyadlulayo, isixhobo ECG yaba umatshini omkhulu kunzima ukuyekelela ukuthutha uthabathe indawo eninzi kweli gumbi. zobugcisa zale mihla ziye ukuba ukunciphisa imilinganiselo yifowuni (ukuya mobile) ngaphandle kokulahleka yomgangatho functionality.

isixhobo ECG Unokurekhoda i amajelo esinye okanye ezininzi, kwaye zisekelwe phezu apho ukwahlulwa ibe ngamaqela. Ukongeza, kufuneka ixhotyiswe kunye software ezithile:

• ingxelo syndromic kwiziphumo ze data;
• waphula umthetho izinga yentliziyo kufuneka ngokuzenzekelayo ukhanyise designated;
• Khetha isixhobo defibrillation kunye nokusebenza yayo manual;
• esweni umsebenzi intliziyo ixesha elide kunye neziphumo abhalwe kwimemori kwefowuni;
• ithuba lokwenza electrocardiogram kunye nezigulane ezininzi ngaxeshanye, ungatshixa data kwinkumbulo;
• isilawuli kude.

izixhobo-channel Single

Ezithi zisetyenziswe kumaziko phantse yonke ezempilo oluntu nawabucala, iinkonzo zeenqwelo zezigulane. Ezo electrocardiograph eziphathwayo enobunzima 1 kg. Le fowuni ihlanganiswe mini-umshicileli ukuba ovelisa idata ECG ephepheni thermal. Kuyenzeka ukuba ukufumanisa ngokuzenzekelayo uxilongo. Loo umatshini ECG unako ukusebenza ukusuka kuthungelwano okanye ibhetri lwangaphakathi.

Kukho kwakhona amancinane imifuziselo ubungakanani (malunga 800 g), nto leyo ethandwayo phakathi paramedics. Kuyenzeka ukuba ukubhala isixa e data amancinci kwimemori yefowuni ukuze ECG. Ixabiso Izixhobo single-channel ku ezahlukene 22-30 amawaka engange.

izixhobo siteshi-amathathu

electrocardiographs ezinjalo sinikwe iziphumo ezintathu-channel thermal umshicileli zizalele nakuzo uphando. Yiba ezi mpawu zilandelayo:

• izibalo yenziwa ngokuzenzekelayo, akufuneki umsebenzi isixhobo ulawulo;
• Thermal iye ukwandiswa ebalulekileyo, ngokuvumela, ukongeza umfanekiso idatha electrocardiogram, chaza ulwazi lobuqu malunga isigulane wasebenzisa precipitator electrostatic, izinga lokonyuka kwi awo kophononongo;
• iziphumo badluliselwe ukuba PC ngenxa vyschityvaniya Iimpawu ezongezelelweyo;
• kusenokwenzeka ukuba defibrillation.

Iindleko irubhrikhi-amathathu ECG na iintlobo amawaka 50 engange.

isixhobo-channel ezintandathu

Loo umatshini ECG kunendawo ngokubanzi isicelo. Bona abasebenzi yeenkonzo zohlangulo, izibhedlele zomkhosi, iinkonzo zeenqwelo zezigulane, kwiiklinikhi zabucala. ECG kunokwenzeka ngeentlobo ezimbini izixhobo-channel ezintandathu: ephathekayo (laptop) iikhompyutha.

iimpawu:

• Ukugcinwa iziphumo uphando malunga 1000 (ifumaneka disk hard nge-10 GB);
• ukuba kuqhuba isaveyi izigulane 150 ngaphandle uyazihlaziya izixhobo;
• yoshicilelo-high speed, endiwenziweyo ngokuzenzekela;
• ukusetyenziswa ubukhulu bephepha multiple ukulungisa iziphumo.

Ukongeza, isixhobo enjalo kuba ECG, nto leyo inani uluhlu 75 amawaka engange, ibonisa kwimo yesixhobo: amandla ebhetri, inkumbulo, ukhuphe i electrode, ilumkisa isiphelo kukuba iphepha ngayo.

Dvenadtsatikanalnye electrocardiographs

Used in amathambo, medicine lwangaphakathi, utyando, iimeko likaxakeka, ngexesha yesiqhelo emva iinkqubo zotyando, ngexesha iinkqubo impilo yomzimba. Ukususwa ECG Le izixhobo ineendlela ezininzi. Isixhobo ikuvumela ukuba abhale iinkcukacha ngeyure omnye isigulane ukuba ufake idatha malunga nomonde, ngokunjalo ukulawula electrocardiograph leyo kwiPC.

Ingongoma umdla kukuba kunokwenzeka ukuqhuba le migangatho kunye, kwimeko yokufumanisa ukutenxa kule isixhobo kuhlolwa iza kubonelela Abuse umqondiso. Yenza ECG ivumela iseti entlantlu ezi zinto zilandelayo:

• electrocardiograph;
• kwikhompuyutha bayakwazi ukunxibelelana kunye nesixhobo ECG ngokusebenzisa introducer okanye besprovodnikovuyu iqhina;
• umshicileli likuvumela ukuba ukushicilela iziphumo ze data lokuxilonga;
• ergometer - isixhobo ezinokusetyenziswa ukuhlola umsebenzi intliziyo umsipha umthwalo eqhagamshelwe electrocardiograph nge Bluetooth;
• software.

izixhobo Iindleko dvenadtsatikanalnyh isusela ukusuka engange-100 ukuya 500 lamawaka, kuxhomekeke ilizwe imvelaphi kunye iseti kwezixhobo.

ucwaningo

Ukulinganisa umahluko amandla asetyenziswa electrode ECG ezilahlwayo, apho kuthelekiswa iinxalenye zomzimba ethile. indawo nitrogen kwi gel uyasetyenziswa, Oku kuphucula conductivity kwesikhumba. Zinjalo ke ngoku, kodwa ngaphambili wasebenzisa isusa of igozi nkxu emanzini amtyuba.

Iiseli Heart kwemisipha kukho umbane ezincinane zombane ukuba phezu isahlakalo lwamaza excitation okanye yehle. Electrocardiogram - umlinganiselo Isiphumo ubuchule ezisebenzayo zezi umbane, ebonisa ukusasazeka ngamaza ombane entliziyweni.

Ntoni ugqirha kwi cardiogram?

Ngokuqhelekileyo lo ECG ungachaza parameters zilandelayo:

1. Barb P - kubonisa indlela depolarization ye imithambo.
2. QRS - ezintsonkothileyo, ebonisa depolarization ventricular.
3. ST ne T wave - repolarization le ventricles.
4. Wave U - neengcali izimvo ezahlukeneyo malunga nokuqeshwa kwakhe. Abanye bakholelwa ukuba igagasi repolarization kungenxa Purkinje imicu ezinye sithetha kwii-potassium kwiiseli intliziyo kwithuba lokuphumla.

Kubalulekile ukuba uyazi indawo ye umkhondo apho umahluko ezinokubakho ulinganiswa njalo. Ukuphanjukiswa ezintathu zokuqala lisetyenziswa kwesebe (electrode ebomvu phezu kwengalo yasekunene, mthubi - ukuya ekhohlo, eluhlaza - phezu unyawo ekhohlo). Kwi unyawo lwasekunene lisetyenziswa electrode abamnyama, engaquki umlinganiselo komsebenzi, kwaye lihlala.

iintambo Precordial, apho kuthelekiswa i electrode ECG (amaphepha):

• V1 - edge lasekunene kwentamo kwisithuba intercostal 4;
• V2 - ushiye edge sternal kwisithuba intercostal 4;
• V3 - nendawo phakathi V2 ne v4;
• V4 - line yee-clavicular kwisithuba intercostal 5;
• V5 - le axillary umgca sobuKristu, ekuhlanganeni kweendlela kunye kwinqanaba tye v4;
• V6 - umgca yee-axillary ekuhlanganeni kweendlela kunye kwinqanaba tye v4;
• V7 - kumgca ngomva axillary ekuhlanganeni kweendlela kunye v4 kwinqanaba othe tye;
• V8 - umgca yee-scapular ekuhlanganeni kweendlela kunye inqanaba tyaba v4;
• V9 - kumgca paravertebral ekuhlanganeni kweendlela kunye inqanaba tyaba v4.

Ezinye iindlela ze ECG

Kukho inani elibalulekileyo ubuchule. Umzekelo, electrocardiography nge emphinjeni. Le mithambo esophageal elawulwa electrode ngendlela esebenzayo. Loo ndlela ulwazi xa kwafa ezahlukeneyo inhliziyo.

Vectorcardiography - ayibobuchule yoxilongo evumela ukulungisa kumda wesangqa zombane ze ukusebenza imisipha yenhliziyo ngokohlobo wokuprojektha yamanani-ntathu endaweni ethe tyaba.

esweni Holter Daily - uvavanyo umsebenzi imisipha intliziyo ekuhambeni kwexesha ixesha elide. Umba HIV kungenzeka yokwenza kuphela zokubhala kodwa ekhaya. Le data uxilongo luyasuka kuye ekupheleni computer, esele gqirha lezifundo zabo.

Gastrokardiomonitorirovanie - kukho nitrogen ngaxeshanye data ECG kunye gastrogrammy iiyure eziyi-24. Kunye nedivaysi electrocardiography nomonde ilawulwa ityhubhu nasogastric, apho idatha afunyenwe kwi-asidi esiswini okanye kuvuleke iminxunya.

Medicine ngokubanzi kunye nezifo zentliziyo ingakumbi, musa ukuma. Ngezixhobo diagnostic uyaphuculwa ngonyaka ngamnye, zibe yemfaneleko amanqaku bezikhethwe kokudlulileyo nezingalunganga.
