Garaaca wadnaha, wadnaha sifo, miiska garaaca wadnaha by da'da

Inta lagu jiro foosha wadnaha nidaamka vascular waxaa laga saaray qayb kale oo ka mid ah dhiigga. ay hit derbiga oo halbowle ah abuuraa gariirka oo dacaayad iyada oo weelashii inay maqnaadaan si tartiib tartiib ah ku baxayn. Waxay sidoo kale noqday loo yaqaan wadnaha ah.

Waa maxay wadnaha?

In aadanaha, waxaa jira saddex nooc oo ah xididdada dhiigga: halbowlayaasha, xididdada iyo qalintaanka. Release of dhiig, waxaa qalbiga ka mid ka mid ah ama qaab kale oo saameyn ku, mid kasta oo iyaga ka mid ah, taasoo keenta iyaga lagu baayici karo derbiga. Dabcan, sida halbowlaha ugu dhow weelasha qalbiga ku yaal ka badan ku xiran tahay saameynta ay wax soo saarka dhanka wadnaha ah. Degidda derbiyadooda ay si fiican u go'aamiyo taataabasho, iyo weelal waaweyn xitaa arki karo in ay isha oo qaawan. Taasi waa sababta garaaca halbowlaha waa ugu weyn lagu ogaado.

Qalintaanka - weelashii dhiig yar ee jirka aadanaha, laakiin xitaa iyagu la kulma wadnaha. derbiyadooda gariiro wakhtiga la garaaca wadnaha, laakiin heerka la go'aamin karaa oo keliya iyadoo la kaashanayo qalabka khaaska ah. Dareemi in garaaca wadnaha gaddoonka ah isha qaawan - calaamad ka mid ah cudurada.

Xididka laga saaro wadnaha si derbiyadooda ma ay simbiriirixan. The wax-u garaaca wadnaha arooriyaha - iibsiga vibrations la halbowlayaasha waaweyn si dhow u dhaxeyso.

Waa maxay sababta loo ogaado wadnaha?

Waa maxay muhiimadda lagu ogaado derbiyada vascular yihiin gariirka? Waa maxay sababta ay tani muhiim u tahay?

Garaaca wadnaha kuu ogolaanaya in aad xukumi haemodynamic ah, sida wax ku ool ah hoos u muruqa wadnaha, oo ku saabsan tirada buuxda oo sariirta vascular, on laxanka ee wadne.

In geeddi socodka badan oo bahal kala duwan garaaca wadnaha, dabeecad u garaaca way joogsatay inay waafaqaan iska caadi ah. Taasi waxay suurto gal ah in ka shakisan tahay in nidaamka wadnaha ma aha xaq oo dhan.

Waa maxay-beegyada uu ogaado wadnaha? Astaamaha u gaarka ah garaaca wadnaha

1. Habsami. Waayo, qalbiga caadi garaaca si joogto ah, oo halkan ka garaaca wadnaha waa in jiibta.
2. Joogtaynta. ruxruxo garaaca wadnaha waa caadi badan sidii qalbigii halkii daqiiqo garaaca.
3. Danab. Heerka Tani waxay ku xiran tahay cadaadiska dhiigga systolic. The sare waa, waa ku sii adkaanaysaa ku cadaadisaa halbowlaha farahaaga, aad ie, garaaca wadnaha danab sare.
4. Buuxinta. Waxay ku xiran tahay mugga dhiigga saaray by wadnaha lagu jiro systole.
5. Tirada. Aragtidani waxa ay isu keentaa content iyo kacsanaanta.
6. Form - waa dhimaya kale oo go'aamisa wadnaha. Tilmaamo garaaca wadnaha ay dhacdo in la siiyo waxay ku xiran tahay isbedelka cadaadiska dhiigga ee weelasha lagu jiro systole (xanuunka foosha) iyo diastole (nasashada) qalbiga ku.

garaaca

Marka xadgudubyada ama jiilka of digir by ee foosha muruqa wadnaha ee dhaqdhaqaaqa wadnaha ku kala duwan yihiin, iyo waxa la, iyo badala wadnaha. isbedbedelka Qaar ka mid ah derbiga vascular bilaabaan inay dhacaan, ama iyaga ula muuqda Dhicis, ama raac mid kale xilliyo aan joogto ahayn.

Waa maxay garaaca?

Garaaca beddelo sanka hawlgalka (qaybtii myocardial oo abuuraa karsado oo keentay in hoos u of muruqa wadnaha)

1. tachycardia Sanqaroorka - kordhay inta jeer ee foosha.
2. Sanqaroorka bradycardia - hoos u dhac in inta jeer ee foosha.
3. arrhythmia Sanqaroorka - garaaca wadnaha oo xilliyo aan joogto ahayn.

garaaca iyo madhalaysnimo. Muuqashadii noqdo suurto gal ah marka diiradda ee myocardium la hawl ka badan Guntin Dalqada wadnaha ku. Xaaladdan oo kale, pacemaker cusub joogsada doonaa waxqabad ee dambe iyo in ay soo rogaan garaaca wadnaha laxanka ay.

1. Beats - ah ee wadnaha caadi ahayn. Iyada oo ku xidhan deegaamaynta ah ee diiradda ectopic of garaaca excitation waa wadne, ventricular iyo atrioventricular.
2. heerka wadnaha oo kordha lama filaan ah (ilaa 180-240 wadne halkii daqiiqo) - Paroxysmal tachycardia. Like garaaca wuxuu noqon karaa wadne, ventricular iyo atrioventricular.

Ku xadgudubka garaaca wadnaha ee myocardium ah (Cunaqabtayntaas). Iyada oo ku xidhan deegaamaynta ah ee dhibaatooyinka hortaagan horumarinta caadiga ah ee Suu dareemayaasha ka Guntin ku sinoatrial ah, Go'doominta qaybsan kooxaha:

1. block Sinoauricular (garaaca wadnaha tagaa sii badan Guntin Dalqada wadnaha ah).
2. block Intraatrial.
3. block Atrioventricular (Suu aan laga soo wareejiyay atria si intraventricular ah). Marka block atrioventricular (degree III) noqdo suurto gal ah in ay jiraan laba pacemaker (node sinoatrial iyo bartamaha excitation in intraventricular wadnaha).
4. block gudeheeda.

Dhanka kale waa on joogo oo bilig bilig ah flutter wadne ama aamba. Xaaladahan waxaa sidoo kale loo yaqaannaa arrhythmia buuxda. Guntin Dalqada wadnaha kiiskan ma aha pacemaker ah, iyo in myocardium ee atria ama intraventricular loo sameeyay Axdigu ectopic badan ee excitation in la qeexo garaaca wadnaha oo leh hoos u soo noqnoqoshada weyn. Dabcan, in xaaladahan, muruqa wadnaha ma aha in ku filan hoos u awoodaan. Sidaa darteed, cudurada (gaar ahaan ka intraventricular) waa naf-gooyada ah.

garaaca wadnaha

garaaca wadnaha xeryo qof weyn waa 60-80 garaac daqiiqaddiiba. Dabcan, tiradaasi kala duwan nolosha oo dhan. Garaaca wadnaha by da'da weyn u kala duwan yihiin.

Waxaa laga yaabaa in farqi ah oo u dhexeeya tirada wadne iyo tirada hirarka garaaca wadnaha. Tani waxay dhacdaa haddii dhiigga saaray mugga dhiigga yar (kaafi wadnaha, hoos u xaddiga wareegaya dhiig). Xaaladdan oo kale ah oscillations derbiyada markabka laga yaabaa in aanay dhici.

Sidaas darteed, qof ee wadnaha (caadi u ah da'da kor ku xusan) aan mar walba ka go'an on xididdada durugsan. Tani, si kastaba ha ahaatee, macnaheedu ma aha in wadnaha ayaa sidoo kale aan la dhimay. Waxaa laga yaabaa in hoos u dhac in jajab ejection.

danab

Iyada oo ku xidhan isbedelka of tilmaame waxaa loo beddelo iyo garaaca wadnaha. garaaca wadnaha sifo danab ee ay horyaalka heerka bixisaa noocyo soo socda:

1. garaaca wadnaha adag. Sababo la xiriira cadaadis dhiig oo sareeya (BP), gaar ahaan systolic. Noqanayaa halbowlaha farahaaga ay dhacdo in tani ay tahay mid aad u adag. muuqaalka kore ee kala duwan garaaca wadnaha this waxay muujinaysaa baahida loo qabo in la saxo si degdeg ah cadaadiska dhiigga daawooyin antihypertensive.
2. garaaca wadnaha oo jilicsan. halbowlaha waxaa si fudud Tifaftirayaasha, oo ma ahan mid aad u wanaagsan, sababtoo ah noocan oo kale ah garaaca wadnaha muujinaysaa cadaadiska dhiigga aad u hooseeyo. Waxaa laga yaabaa in ay sabab u tahay sababo kala duwan: hoos u mugga dhiigga, yareynta midab vascular, wadne hawlqabad la'aan.

buuxintii

Iyada oo ku xidhan isbadalada tilmaame waxaa soo socda noocyada kala duwan ee wadnaha:

1. Full. Taas macnaheedu waxa weeye in wareegga dhiigga halbowleyaasha ku filan.
2. Faaruqa ah. garaaca wadnaha tani dhacdaa marka mugga yar oo ah dhiigga saaray by wadnaha lagu jiro systole. Sababaha gobolka noocan oo kale ah waxa ay noqon karaan cudurada wadnaha ka mid ah (wadnaha, arrhythmia la garaaca wadnaha oo aad u badan) ama hoos u dhac in mugga dhiigga ee jidhka ku (dhiig la'aan, fuuq-bax).

Qiimaha wadnaha

Tilmaamahan isku daraa ee content iyo garaaca wadnaha danab ku. Waxay ku xidhan tahay ugu horrayn on ballaarinta halbowlayaasha foosha wadnaha iyo nasashada ee Wadnaxanuun suuska ay. magnitude oo ka mid ah noocyada soo socda ee wadnaha:

1. Large (sare). Waxay dhacdaa in xaalad ay jirto koror ee jajabka ejection iyo hoos u midab derbiga halbowlaha. magnitude ee cadaadiska ku systole iyo diastole kala duwan (waayo, mid wareegga wadnaha ee hawlgalka waxay soo maratay soo baxdo, ka dibna si weyn hoos). Sababaha keentay in dhacdo ee garaaca badan oo laga yaabaa in kaafi aortic, thyrotoxicosis, qandho.
2. garaaca wadnaha Small. Dhiigga ee vascular ka saaray derbiyada halbowlaha midab yara dheer yahay, isbedbedelka cadaadiska ee systole iyo hooseeyo diastole ah. Sababaha gobolka this: stenosis aortic, wadnaha oo shaqadiisa gaba, hemorrhage, si lama filaan ah. Xaaladaha daran, qiimaha garaaca wadnaha wuxuu noqon karaa qof yar (tani waxaa la yiraahdaa garaaca wadnaha a thready).
3. garaaca wadnaha Lebis. Waxaa lagu gartaa sida qiimaha garaaca wadnaha waa caadi.

Qaabka uu oscillation wadnaha

On dhimaya this wadnaha waxaa loo qaybiyaa laba qaybood oo waaweyn:

1. Fast. Xaaladdan oo kale, inta lagu guda jiro systole cadaadiska ee quseyo waxaa aad u kordhay, iyo in diastole si degdeg ah hoos. garaaca wadnaha oo degdeg ah waxaa ku Sugan Calaamad sifo kaafi aortic.
2. Gaabis ah. Xaaladda soo horjeeda, taas oo ay jirto hoos u dhac cadaadiska weyn ee systole iyo diastole. garaaca wadnaha noocan oo kale ah sida caadiga ah waxay muujinaysaa joogitaanka stenosis aortic.

Sidee si sax ah u baaraan garaaca wadnaha?

Malaha qof walba ogyahay waxa loo baahan yahay in la sameeyo si loo ogaado waxa garaaca wadnaha qofka. Si kastaba ha ahaatee, xataa sida fudud ku salaysayn khalkhalgelinta uu leeyahay muuqaalada in aad u baahan tahay in la ogaado.

Garaaca wadnaha imtixaanay durugsan (radial) iyo jirridda (artery) halbowlayaasha. Waxaa muhiim ah in la ogaado in ee wax soo saarka yar yahay wadnaha on maqnaadaan ee hirarka atar aan la ogaan karaa.

Bal ka fiirso sida ay u palpate garaaca wadnaha ee gacanta. halbowlaha radial diyaar u ah cilmi baaris ku dusha ka hooseeya salka suulka. Marka go'aan laga wadnaha taataabasho labada halbowlayaasha (bidix iyo midig), sida waxaa laga yaabaa in xaaladaha marka la karsado cadaadis kala duwanaan doontaa labada hubka. Tani waxay noqon kartaa sabab u riixo of weelka ka baxsan (tus, burada) ama qabsamin of Lumen ay (thrombus, huurada atherosclerotic). Ka dib markii barbar wadnaha cabbiro on gacanta meesha ugu fiican taataabasho. Waxaa muhiim ah in daraasad ah ee isbedbedelka garaaca wadnaha ku dhaca halbowle ma uu farta ka mid ah, oo dhowr (ugu wax ku ool ah hareerayn gacanta si ay 4 faraha, suulka mooyee, waxay ahaayeen on halbowlaha radial).

Sidee waa garaaca wadnaha ee artery? Haddii hirarka garaaca wadnaha durugsan waa mid aad u liita, aad sahamin karaan garaaca wadnaha ee weelashii weyn. Habka ugu fudud ee ay isku dayaan oo ay heli on the artery. Si arrintan loo sameeyo, labada farood (index iyo dhexe) waa in lagu shubaa on meesha halbowlaha u saadaaliyey qeexan (at Geesta hore ee muruqa sternocleidomastoid sare inankeeda Aadan). Waxaa muhiim ah in la xasuusto in xaq u leedahay in ay baaritaan ku garaaca wadnaha ee labada dhinac waa wax aan macquul aheyn. Riixaya oo ka mid ah laba halbowlayaasha artery keeni kartaa rabshooyin wareegga dhiigga ee maskaxda ku jira.

Garaaca wadnaha nasan iyo waxqabadka hemodynamic caadi ka yar si fudud go'aamiyey sidii durugsan iyo weelashii dhexe.

A dhawr eray ee gabagabo

Qofka garaaca wadnaha (da'da caadiga ah waa in ay daruuri tahay in la tixgeliyo daraasadda) u ogolaanaya in ay gebagebo ku saabsan gobolka hemodynamics. Kuwani ama isbedel kale oo xuduudaheedu oscillation garaaca wadnaha ayaa inta badan ah muuqaalada caan ku ah dalalka bahal ah qaarkood. Taasi waa sababta baadhitaanka ee wadnaha waa qiimo cudur-weyn.
