Bated neefta: sababaha iyo daaweynta

Taago waxyaalaha qalbiga ku jira - daaweynta cudurkan sannadihii la soo dhaafay yididiila maskaxda ee ay yeelanayaan dhakhaatiirta badan wadnaha, iyo "qalbi" kale oo khaas ah. Waa maxay sababta, waxa astaamaha cudurkan khatarta ah, sida loo daweeyo - kuwani waa kaliya arrimaha qaar ka mid ah oo Ribo ah si muwaadiniinta. Waa wax qarsoodi ah ilaa xad tiro badan oo ah dadka waxay leeyihiin ogaanshaha sida "qalbi taago" sida. Calaamadaha, daaweynta daawooyinka dad, f hay'adaha gaarka ah, cudurka - fikradaha kuwan waa in laga fekeraa in qof kasta oo uu leeyahay calaamadaha cudurka. The warbixinta kooban ee soo socda qaar ka mid ah arrimaha hadda ee mawduuca.

Bated neefta: sababaha iyo daaweynta

Waxay sababi dareen ah "engegay" in qalbiyada shaqada noqon kartaa noocyo kala duwan oo garaaca iyo tabinta rabshooyin. Qaar ka mid ah dalalka kuwaas oo aan u baahnayn faragelin caafimaad, iyo qaababka kale ee dib u dhac ku ah ogaanshaha iyo daaweynta noqon karaan kuwo raga. Kala supraventricular iyo ventricular garaaca.

garaaca supraventricular

Waa hawl dhicis koronto ee wadnaha. Sababta waa isha in waxa uu ku yaalaa ee atria iyo xididdada pulmonary of godkii iyo isgoyska atrioventricular. Ka dib markii sida hoos aan caadi ahayn horumariyo karaa qayb ahaan ama gebi hakin postextrasystolic. garaaca dhicis joogta ah oo hakin muddo dheer ka dib markii hoos u caadi ku siin kara ubaxuna wuu dareen, carqalad waxyaalaha qalbiga ku jira.

muhiimadda Independent caafimaad ee noocyada kuwaas garaaca, marka laga reebo kuwa xaaladaha marka ay tahay muuqashada waxay bilowdey in ay u ordaan tachycardias supraventricular, flutter wadne ama wadne.

Maqnaanshaha cilladaha dhismaha ee muruqa wadnaha extrasystoles supraventricular daaweyn gaar ah looma baahna. Xaaladaha meesha ay ku weheliyay raaxo shakhsi ahaan la taaban karo, beta-blockers, verapamil, dajiya waxaa loo isticmaali karaa.

Inta badan extrasystoles supraventricular waa muujin ka timid cudurka ugu weyn ee (dystonia, chronic obstructive pulmonary disease, disorder elektrolytka), markaas cudurka u baahan yahay dib uhabaynta iyo daaweynta habka dahsoon.

extrasystolic aamba Ventricular

extrasystoles Ventricular - waxqabad saadaalin koronto ee wadnaha ee la xiriirta laxanka ugu weyn ee u shidan garaaca wadnaha oo sababo lugaha ama kala duwanaanshaha laan block xidhmo, Oriyon ama Purkinje shaqeeya myocardium. Ka dib markii geedi socodka si weyn u badan tahay in hakin magdhawga buuxa, taas oo, sida in ay dhacdo garaaca dhicis wadne, dareemay in qaab "engegay" kuwan. geeddi socodka Ventricular aan wayn Fadilid mid ka mid ah cudurka wadnaha organic ma aha arrin khatar geeri kedis ah, sidaas darteed aan la daaweyn. Ka reeban bukaanka caafimaad qaba syndromes dhaxlo (muruqa lagu dhasho ama yaraynta ka mid ah syndrome QT, Brugada, iwm).

Taago waxyaalaha qalbiga ku jira, sababla'aan iyo calaamadaha, kuwaas oo loo arko inay ka dhacaan iyada oo sababtu tahay a garaaca wadnaha dhif.
heerka A wadnaha caadi ah waxaa ka go'an 60 ilaa 100 naxdin leh halkii daqiiqo gudahood. Dhimitaanka nafsaaniga ah waxaa qalbiga ka soo dhici kara marka la seexdo, marka la neefsanayo qoto dheer, in ciyaartoyda.

In case of xadgudub heer kasta oo qarni ka mid ah garaaca wadnaha uu yeesho bradycardia bahal ah, kaas oo noqon kara astaamaha, astaamo, iyo inta badan u baahan tahay daawayn.

Sababaha bradycardia

Kala saaro sababaha gudaha iyo dibadda ee bradycardia.
Sababaha gudaha waxaa ka mid ah:

• gaboobaya,
• wadne xanuunka,
• cudurka unugyo;
• cudurada lagu dhasho, oo ay ku jiraan itaaldarrada Guntin ku atrioventricular;
• amyloidosis muruqa;
• trauma qalliinka (filtarka laga hagayo, wadnaha-tallaalidda) ;
• cudurrada faafa (diphtheria, cudurka wadnaha rheumatic, dhiigga oo sumooba, qandho tiifowga).

By arrimaha dibadda ee bradycardia ka mid ah:

• tababar jireed,
• elektrotonus vagal afaysteen (mugdiga vasovagal, sanka supersensibly artery);
• daroogada (beta-blockers, blockers calcium channel, digoxin, lithium, wakiilada antiarrhythmic);
• cocaine,
• hypokalemia;
• hyperkalemia;
• xanuunada maskaxda ah (habdhiska buro, kordhay cadaadiska intracranial);
• Obstructive xibin gal, hurdo syndrome.

Waayo, cudurka isticmaalka bradycardia qabashada socodka Holter, counters dhacdada iyo rikoorrada, qalabka implantable, iyo sidoo kale fulinta waxbarasho ah ee elektarooniga ah.

daaweynta bradycardia

Tallaabada ugu horreysa waa in la ogaado sababaha keena iyo tirtiridda suurto gal bradikaridii ay falsayeen (joojiyo of beta-blockers). Haddii aanu jirin salka saari karo, waxaa laga yaabaa in aad u baahan tahay daaweynta daroogada ama laso- ku meel gaar ah ama joogto ah).

daawo

Si aad u kicin garaaca wadnaha deceleration muhiim ah (muddo ka badan 3 ilbidhiqsi) isticmaalaya atropine, isoproterenol, aminophylline. Si kastaba ha ahaatee, qaadashada daroogada, kuwaas oo kicin kara garaaca, oo ay ku jiraan rabshooyin ventricular naf-gooyada ah.
In bukaanka qaba ischemia myocardial iyo bradycardia ay sabab u tahay, ku qaataan therapy antiischemic oo waxaa islamarkaana ay mar, iyadoo la isticmaalayo laso- haddii loo baahdo.

Bukaanka qaba kaarka syndrome murugada sanka iyo block atrioventricular waxaa lagu qiimeeyaa in ay dejiyaan pacemaker ah ku meel gaar ah ama joogto ah.
Waxaa horumariyo muujinaya European loogu rakibo ee pacemakers joogtada ah ee bukaanka qaba buka syndrome sanka, block atrioventricular.

kala duwan ee kiciya

Kala stimulators-hal qolkii, dual-qolkii, saddex-qolkii. Hayso electrodes koowaad iyo labaad 1 iyo 2 (wadne iyo / ama ventricular midig). qalabka Saddex-qolkii waxaa loo isticmaalaa dardargelinta biventrikulyatnoy oo ay guide dheeraad ah ventricle bidix.

Marka xaq synchronism ventricular kicinta wadne-loo jeediyo. ECG ayaa inta ay socoto waxaa loo oggollaan go'doomin xaq block laan xidhmo.
Marka kicinta labada intraventricular raagayaan ay hawlgal synchronous, hemodynamics wadnaha ay dhacdo in this, aad u fiican.

tallaalmid

unit ugu horeeya ee sida la aasaasay 1958. In ka socda waa horumar. Haddaba waxaa casri ah, aad u yar, qalabka-teknoolojiyad sare.

Currently, waxaa jira warshad sanadle ah ka 400 1,200 kiciya halkii dadka million.

Kardiopribor ayaaba dardargelinta korontada ee myocardium ah. signal ayaa kobciya weheliyaan muruqa wadnaha by non-jir. Uu gaadhista muddo dheer waxay keeni kartaa isbedel korontada iyo farsamo ee myocardium ah. rakibo waxaa loo baahan yahay in la soo saaray saameeyaan tilmaamo halis ah.

Maqaallo hababka Carbinta

Inta lagu guda jiro ventricular xaq laso- garaaca wadnaha korontada waxaa laga codsadaa in Cardiff oo ventricular bidix iyo depolarizes myocardium medlennoprovodyaschy. ECG ayaa waxa lagu sheegay go'doominta reer xidhmo bidix laan block. bukaanka noocan oo kale ah waxay leeyihiin jajab hoose ejection badan bukaanka aan go'doominta. Sidoo kale, marka nidaamka ay taasi dhacdo habeysan wadnaha korontada. Recently, waxaa caadi u ah si loo yareeyo muujinaya ee xogta kiciya rakibo oo xidhiidh la leh tiro badan oo isbedel loo kasin.

Waxaa la aasaasay in jajab ugu hooseeya ejection sameeyay hoos tallaabada of intraventricular ah. Celceliska - hawshooda u ah ee atria ah, ka dibna inta kale ee wadnaha. The jajab ejection ugu sareeya sii raagayaan inta lagu jiro kicinta ah atria iyo intraventricular oo ka mid ah wadooyinka dabiiciga ah.

Caddeeyeen in aamba yar horumaray wadne in bukaanka qaba hawshooda u arko wadne oo ah laba aqal ka badan ee bukaannada qaba ventricular keliya saamayn ka mid ah qalabka.

The qalab dual-qolkii, cilmi baaris la xaqiijiyay iyo tijaabo, waxaa wanaagsan in bukaanka firfircoon jir ahaan waa.
Pacemakers hadda jira ee caadiga ah oo dahab ah ee daaweynta bukaannada qaba bradycardia astaamaha ah. search waxa uu sii wadaa inta badan wadooyinka nafsaaniga ah ee saamaynta togan ee myocardium ah.

gunaanad

Sayidka, dagistii ee wadnaha (gama'did ama xaalado kale) - cudur aad khatar u ah. Marka calaamadaha ugu horeeya ee cudurka waa in isla markiiba la xiriir isbitaalka si ay u fuliyaan dhammaan baaritaanyada iyo si taxadar leh loola dhaqmo. The daaweynta ku bilaabatay si ka dhaqso iyo ka hortagga, ayaa in ka badan wax ku ool ah u noqon doonaa daawaynta.
