Echocardiography Stress: Tabaha loogu talagalay

Modern hababka ogaanshaha cudurka wadnaha gaadhay hufnaan aan horay loo arag. Waxa intaa dheer in ECG caadiga ah, waxaa jira liiska siyaabo in lagu ogaado cilladaha. Mid ka mid ah hababka casriga ah inta badan wax ku ool ah ay guushu ku echocardiography stress la jimicsi. Tani waxa ay muujinaysaa cudurka? Waa maxay shuruudaha ku jira nidaamka? Maxaa loogu talagalay walwalka echocardiography? Waxaan isku dayi doonaa in aan ka jawaabo su'aalahan oo kale.

Waa maxay echocardiography stress?

ECG Stress - habka cilmi-baarista cudurada ischaemic Modern oo ah waxa lagu gartaa fulinta abuurista load jirka bukaanka, taas oo keenta in la kordhiyo inta jeer ee foosha muruqa wadnaha.

Local rabshooyin of contractility qofka qaybaha oo ah cad toos ah calaamad ka mid ah cudurada. Xaaladaha intooda badan, si uu u xaliyo weecasho ugu yar ee muruqa wadnaha lagu jiro ECG caadi nasan waa suurtogal aheyn. On lid ku ah, echocardiography stress kuu ogolaanaya in aad si sax ah loo ogaado jiritaanka heley ischaemic in marxaladaha hore ee horumarinta.

Taariikh kooban

Mabaadi'da ogaanshaha farsamooyinka la tilmaamay in caafimaad suugaanta by the American cilmi of ischaemic wadnaha cudurada R. koritaanka iyo L. Vann 1979. A dhowr sano ka dib ugu horeeyay ee taariikhda of stress echocardiography ee ka siman wareegga ergometer ahaa sameeyaa. In ka socda co-qorayaal treatises sayniska Erbel L. iyo C. Berthet, kuwaas oo ku biiray mashruuca, la soo jeediyey in lagu badalo waxqabadka jirka iyo isticmaalka hababka pharmacological electrostimulating saamaynta on nidaamka wadnaha iyo dadka bukaanka ah ee waxbarashada.

In dhaqanka qoyska, horumar ah ee habka cudur-qaadataa Alekhin. "Echocardiography Stress" (format PDF) hadda waa in maamulka baahida. In shaqo ee kor ku xusan cilmiga ah ee cilmi-a tusi waayo-aragnimo oo dhan Baadhista ah, wxbarashada ah sannado badan. Halkan, khabiir ku ahaa awoodaan si ay u muujiyaan saldhigga caddaynta, taas oo Xaqiijiyay waxtarka nidaamka si ay u bartaan ischemia wadnaha, cudurada kale ee wadnaha.

mabda 'ogaanshaha

echocardiography Stress ku salaysan yahay u weeyn in formation of myocardium ee ischemia wadnaha dara awoodda contractility ventricular bidix ee halbowlaha wadnaha. shardi A horumarinta cudurada waa xadgudubyada socodka dhiigga arooriyaha.

echocardiography Stress kuu ogolaanayaa inaad si ay u qoraan falcelinta oo ka mid ah goobaha gaarka ah ee myocardium ee ventricle bidix si ay u sii xoojiyeen, load ka kadis ah iyo cunfiga on jirka ah ee bukaanka ah. Marka laga soo tago nidaamka wadnaha iyo gobolka markii ay bateen cilmi fuliyay qaab imaging isku midka ah ee muruqa wadnaha qaab muuqaallo kale, taas oo ka dhigaysa habka hab wax ku ool si ay u qabtaan cudurka dhamaystiran.

Survey Diyaarinta

In loogu diyaar cudurka of a bukaanka magacaabay diyaarinta dawooyinka soo dhaweynta ka kooban Nitrate, kaas oo u ogolaanaya si aad u yarayso xaddiga garaaca wadnaha, loo yareeyo cadaadiska dhiigga. Sayidka ilaalinta waa muruqa wadnaha by guud ahaan adrenaline firfircoon hoos ugu rarataan culaysyo stress, taas waxay keeni kartaa sii daraysa xaaladda guud ee bukaan-socodka.

Maalinta daraasadda bukaanka loo ogol yahay in ay isticmaalaan nitroglycerin oo jaray angina tahay. Si kastaba ha ahaatee, gelitaanka ee alaabta ay ku jiraan walaxda, bukaanka waa in loo horumariyo wadnaha digniin.

Talooyin ku echocardiography stress ka mid ah failure oo jidhiidh ah ee ku saabsan 6 saacadood ka hor inta cudurka. cilmi-baarista ka hor ayaa sidoo kale soo dhaweeyay ka cabbaan kooban. Maalin maalmaha ka mid ka hor inta cudurka bukaanka loo baahan yahay in la siiyo ilaa caffeine, sababta oo ah saamaynta tonic on jidhka saamayn kartaa saxnimada natiijada. Isla markiiba ka hor howlqabadka waa mamnuuc in sigaar.

Tilmaamayaasha for ogaanshaha

In waxa Xaaladaha waa noocan oo kale ah cudurka? echocardiography Stress lagu qoro bukaanka:

• Haddii aad ka shakisan tahay in horumarinta ischemia myocardial;
• u baahan tahay si ay u qiimeeyaan xaaladda halbowleyaasha wadnaha;
• daraasadda meelmar ah ee myocardial unugyada;
• qaba cudurada wadnaha ah, foomamka chronic ee wadne xanuunka ,
• u baahan tahay in ay sameeyaan qalliin in qalliinka isku tallaalidda, stenting, angioplasty of halbowleyaasha wadnaha;
• baahida loo qabo in la qiimeeyo natiijada therapy iyadoo la isticmaalayo daroogada;
• xirrira saadaasha cudurka wadnaha,
• qiimeeyo suurtagalnimada dhibaatooyinka daaweynta cudurrada wadnaha ka dib;
• diyaarinta hawlaha adag ee wadnaha, sambabada, quseyo,
• baahida loo qabo in la ogaado cilladaha lagu dhasho ee filtarka wadnaha;
• baaritaan loogu talagalay in lagu qiimeeyo awoodda bukaanka in ay ka shaqeeyaan.

sababo

By dhibaatooyin caafimaad, joogitaanka kaas oo aan ku adkaysato kartaa echocardiography in Vladimir, iyo magaalooyin kale, waa horumarinta Wadnaxanuun myocardial in marxaladda ba'an. Looma oggola in ay wax ka barato iyo bukaanka qaba aneurysm aortic, halbowlaha stenosis daran, gabsiiya wadnaha, ciladaha wadnaha ee lagu dhasho. Sababtoo ah khatarta ah ee urka oo ka mid ah khaanadaha ka mid ah xinjiro dhiig oo muruqa wadnaha, echocardiography stress la jimicsi waa u bukaanka qaba thrombophlebitis qaab daran. Sababta failure ee nidaamka sidoo kale qaybaha idiosyncrasy wakiilada pharmacological in si qasab dawadu jidhka loogu diyaar daraasadda.

sababo qaraabo

Marka stress baaritaan degdeg ah waxaa laga yaabaa in maado si:

• dumarka uurka leh;
• dadka qaba xanuunada maskaxda yar;
• Bukaan-socodka ay dhibaatadu ka buurnaanta;
• dadka qaba xanuunka qayb function ganaca,
• Sonkorowga qaba, kuwaas oo arkay decompensation daliilka ugu weyn ee cudurka.

Go'aanka si ay u qabtaan cudurka ee ka mid ah qaybaha bukaanada helo dhakhtar.

imtixaanka loading

echocardiography Stress (N. Novgorod ama magaalo kale - arrinta ma halkaas oo waa la fuliyay) lagu fulin karaa iyadoo la isticmaalayo baaritaano loading kala duwan. dabiiciga ah ee imtixaanka waxaa lagu go'aamiyaa hawlaha iyo xaalad caafimaad oo ujeedadu. Tusaale ahaan, si loo ogaado dulqaad ah ee bukaanka in xamuulka sare, iyo sidoo kale looga shakisan yahay, dalalka infarct horumarinta tahay billaabeen inay baarka firfircoon. Xaaladdan oo kale, daraasadda waxaa lagu fuliyaa iyadoo la isticmaalayo lagu ordo ama bushkuleeti ergometer ah.

More fududaan bukaanada waayeelka dhaqmo load lagu ordo. Gaar ahaan, habkan in aan sameeyo dhirfinaya ogaanayo xanuunka radicular laga yaabaa in la horumariyo marka la isticmaalayo ergometer, taas oo qofka bukaanka ah in uu boos aan raaxo fadhiisan. Faa'iida ugu muhiimsan ee lagu ordo adeegta wax fursad u dhalin garaafyada la natiijada waxbarasho si toos ah waqtiga baaritaanka. Factor, taasoo muujinaysa in loo baahan yahay dhameystirka imtixaanka ciriiriga ka sarreeya heerka caadiga ah wadnaha.

imtixaanka pharmacological

Qiyaastii 40% ka mid ah bukaanka u baahan stress echocardiography in Yekaterinburg oo kale magaalooyinka aan karin inay ku filan kala iibsiga korodhka jirka load. bukaanka noocan oo kale ah soo qoray dil imtixaanka pharmacological.

Waxaa hadda loo stress echocardiography "dobutamine". Maamulka walax waxay fursad si ay u kiciyaan xaaladaha dhaca inta lagu jiro jimicsi. Isticmaalka ayaa sheegay in xal kordhin kartaa dhiig-karka, kordhin contractility ee muruqa wadnaha. Kobaca shuruudaha oxygen unugyada marka la isticmaalayo daroogada sababa calaamadaha in gundhig fiican calaamadaha ischemia myocardial.

Haddii kale, "dobutamine" inta badan loo isticmaalaa "Dipyridamole". Baaritaanku wuxuu ku salaysan yahay korodhka tartiib ah in qiyaasta walax ee jirka. At talaabo kasta oo aan baaritaan ku joogitaanka contractility wadnaha. Haddii xeerarka mudnaanta ay maamusho "Dipyridamole" shaqeeyo tilmaame in garaaca wadnaha waa 120 garaac daqiiqaddiiba, sii codsatay dose "Atropine" qadarkuu of 1 mg. On dhamaystirka baaritaanka intravenously maamulay 240 mg ah "Aminophylline" - daroogada in u dhaqmo fiqiira "Dipyridamole".

Falanqaynta of natiijooyinka

Natiijada echocardiography stress ku adeegta si ay u helaan muuqaallo laba dhinac-cabbir. Arintaan bixiyaan suurtagalnimada in la aqoonsado fashilaad in contractility ee ventricle wadnaha bidix. Marka la fasiraayo natiijada tixgeliyaan ku dhagid iyo dhaqdhaqaaqa unugyada myocardial meelaha ay shakhsi.

Falanqaynta hordhaca ah garaafyo, takhasus u leh isla markiiba ka dib markii iyaga la helo. On dhamaystirka of wadnaha ogaanshaha arki kartaa video ee waxbarashada dhaqaaq tartiib ah. jajabkii Qaar ka mid ah nidaamka waxaa inta badan ku kaydsan saxannada computer iyo in la siiyo saldhig warar fiican nidaamka lagu ogaanayo xiga.

Xagee stress echocardiography?

Si ay u qabtaan daraasad la isticmaalayo baaritaanka load ama imtixaanada pharmacological, ku filan si ay uga dalbadaa goobaha cardiography ee kuugu dhow. Karaa inuu ogaado fasal khaas ah hay'adaha caafimaadka dadweynaha. Doorashadan A qaali ah dhaqangelinta nidaamka noqon karaa ballan rugta caafimaadka ee gaarka loo leeyahay, taas oo uu leeyahay qalabka lagama maarmaanka ah si ay u qabtaan baaritaan oo uu leeyahay khubaro aqoon.

Faa'iidooyinka ogaanshaha of ischemia myocardial isticmaalaya echocardiography stress

Waxaa ka mid ah faa'iidooyinka ugu weyn ee habka yihiin kuwan soo socda:

• Liiska cajiib ah qaababka waxbarasho ee shaqaynaya ee muruqa wadnaha.
• Qaadashada qalabka echocardiographic in awoodo gudashada baaritaano ka baxsan isbitaalka.
• The kharashka yar ee cudurka.
• Waxaa laga yabaa in qiimaynta tayada ee dabiiciga ah ee adag ee myocardium ah.
• nidaamka ammaanka bukaanka.

ceebaha

Haddii aan ka hadlo oo ku saabsan khasaaraha echocardiography stress, waxaa xusid mudan koowaad ee dhibaatooyinka oo dhan lagu qiimeeyo natiijada taranta ee shaybaarka. Sababtan darteed, go'aanka natiijada sax ah ayaa suuragal ah keliya inta lagu guda jiro cudurka soo maray, cilmi xirfad sare leh.

Waxyaabaha kale, inta imtixaanka lagu jiro inta badan waxaa jira dhibaatooyin farsamo. jaaniska ay muuqaalka dhexe ee amarka of 5-10%.

Gebogebadii

echocardiography Stress weli taagan hab ilaa xad cusub oo cilmi-baarista cudurka wadnaha. Hirgalinta cudurka noocan oo kale ah waxaa ugu horayn loo xilsaaray in bukaanka isku dayay tusaalooyinka electrocardiographic caadiga ah aan bixiyo macluumaad ku filan si ay u aqoonsadaan heley. Ugu dambeyntii, echocardiography stress ka dhigayaa suurto gal ah in la ogaado stenosis of halbowleyaasha wadnaha, sawirka weli ma cadda ANGIOGRAFI KADIB.
