Waayo, calaamadaha qaar ka mid ah, iyo in la garto sida loo daweeyo tachycardia ventricular?

Waxaa lagu tilmaamay tachycardia ventricular dardar-garaaca wadnaha ka badan 100 garaac. / Min. iyadoo xarunta of dhacdo in ventricle ah. In 90% ee kiisaska ay dhacdo in dadka la lesions organic ah garaaca wadnaha. Inta badan, qas laxanka la xiriira cudurka halbowlaha wadnaha. Waxa kale oo jira tachycardia ah waxay keeni kartaa Wadnaxanuun myocardial, cudurka wadnaha ee lagu dhasho iyo rheumatic iyo noocyada kala duwan ee dhibaatooyinka ka dib markii therapy daawooyinka psychotropic ama suuxinta qaarkood.

calaamadaha

jaaniska cudurkan kordhiyaa da'da. Ragga isaga bandhigi ilaa xad ka weyn haweenka. Dadka da'doodu ka yar tahay 35 sano ka dhanka ah asalka ah myocarditis ah, cardiomyopathy hypertrophic sidoo kale laga yaabaa in ventricular tachycardia. Calaamadaha waa sida soo socota:

• dareen wadno, wareer, welwel,
• neefta oo ku qabata, xanuunka xabadka;
• Taagan qoorta;
• mararka qaar weeraro of tabar iyo suuxid.

pathophysiology

tachycardia Ventricular dhacdaa laba nooc: monomorphic iyo tachycardia polymorphic. noocyada Monomorphic waxa lagu gartaa isku xigxiga oo ka mid ah excitation pulsed lagu hayaa si joogta ah. Waxaa dhacaya in muujinta noocan ah tachycardia dhacdaa in dadka qalbi qaab caadi ah. Xaaladahan, saadaasha caafimaad caadi ahaan wanaagsan. tachycardia ventricular Polymorphic kala tirayn ee isku xigxiga ee ay hawshooda u ah intraventricular ah. Sababta oo ah cudurka noqon karaan myocarditis, ischemia ama aan caadi ahayn hidde in qaab-dhismeedka channels ra'iyi.

daaweynta tachycardia

Daaweynta tachycardia ventricular waxaa la qabtaa by tallaabada ee daroogada antiarrhythmic, taas oo Ballaariyay ku saabsan asalka ah tallaabooyin wax looga qabto cudurka sababaya. Sida wakiilka antiarrhythmic waxaa inta badan laga codsadaa lidocaine. Waxaa maamula intravenously at 1 mg halkii kiilo ah oo miisaankeedu yahay bukaanka. Sida caadiga ah, this qiyaasta ilaa 100 mg oo waxaa maamula in dhowr daqiiqo. Haddii aan waxtar lahayn 15 daqiiqo diyaarinta waxaa mar kale loo isticmaalo in la mid ah qiyaasta. Haddii tachycardia ventricular waxaa ku weheliyay dhibic cadaadis ah, waxay ku kordhin adigoo isticmaalaya amines pressor. Tani waxay soo celin doonaa laxanka sanka. Sarkhaan glycosides wadnaha tachycardia ventricular daaweeyaa chloride potassium iyo lidocaine ama daroogada "obzidan" waxaa loo isticmaalaa.

Sii daaweynta ka dib markii garaaca wadnaha kabashada

Marka laxanka soo celiyay lagu qiyaasay saadaal iyo qorshaha maamulka bukaanka la soo saaro. Waxa uu magacaabay therapy daroogada ama rakibaadda cardioverter-defibrillator ama ablation kateetarka. Sidoo kale waxaa jira fursadaha daaweynta la isku daro. Waxa ay inta badan la isticmaali karaa marka ay jirto a cillad halis ah dhismaha waxaa qalbiga ka soo. ablation kateetarka, tusaale ahaan, waxay kordhin kartaa hufnaanta therapy antiarrhythmic, ama hoos u dhigi doontaa heerka dheecaan ka mid ah cardioverter-defibrillator nimo ah.
