Ventricular tachycardia

Ventricular tachycardia (VT) bụ ngụgụ obi ngwangwa nke na-amalite n'ime ime ụlọ ala nke obi (ventricles).

VT bụ ọnụọgụ ihe karịrị 100 kwaa kwa nkeji, ma ọ dịkarịa ala, obi mgbawa 3 na-adịghị agbanwe agbanwe.

Ọnọdụ ahụ nwere ike ibilite dị ka mmalite ma ọ bụ mbubreyo nke nkụchi obi. O nwekwara ike ime na ndị nwere:

• Cardiomyopathy
• Obi mgbawa
• Surgerywa ahụ obi
• Myocarditis
• Ọrịa obi Valvular

VT nwere ike ime n'enweghị ọrịa obi.

Akara ụfụ nwere ike ịdị na akwara nke ventricles ụbọchị, ọnwa, ma ọ bụ ọtụtụ afọ mgbe nkụchi obi gasịrị. Nke a nwere ike iduga ventricular tachycardia.

VT nwekwara ike kpatara:

• Anti-arrhythmic ọgwụ (eji na-emeso ihe ndiiche obi n'afọ iri na ụma)
• Mgbanwe onwu ọbara (dị ka ọkwa potassium dị ala)
• Mgbanwe na pH (acid-base)
• Enweghị oxygen zuru ezu

"Torsade de pointes" bụ otu ụdị VT. Ọ na-abụkarị n'ihi ọrịa obi ma ọ bụ ojiji nke ọgwụ ụfọdụ.

Nwere ike ịnwe mgbaàmà ma ọ bụrụ na obi obi n'oge a na-eme VT ngwa ngwa ma ọ bụ na-adịte aka karịa sekọnd ole na ole. Mgbaàmà nwere ike ịgụnye:

• Obi erughị ala (angina)
• Faining (syncope)
• Isi ma ọ bụ dizziness
• Mmetụta nke inwe mmetụta obi (palpitations)
• Iku ume ọkụ ọkụ

Mgbaàmà nwere ike ịmalite ma kwụsị na mberede. N'ebe ụfọdụ, enweghi mgbaàmà ọ bụla.

Onye nlekọta ahụike ga-achọ:

• Enweghị pulse
• Loss nke nsụhọ
• Nkịtị ma ọ bụ obere ọbara mgbali
• Otutu usu

Ule nke enwere ike iji chọpụta tachycardia ventricular gụnyere:

• Nyochaa Holter
• ECG
• Intracardiac electrophysiology ọmụmụ (EPS)
• Nlekọta ndọtị na loop edekọ ma ọ bụ ngwaọrụ

May nwekwara ike ịnwe kemịkal ọbara na nyocha ndị ọzọ.

Ọgwụgwọ dabere n’ihe mgbaàmà ya, yana ụdị nsogbu ọrịa obi.

Ọ bụrụ na onye nwere VT nọ na nsogbu, ha nwere ike ịchọ:

• Atụtụ
• Cardioversion (ọkụ eletrik)
• Ọgwụ (dịka lidocaine, procainamide, sotalol, or amiodarone) enyere site na akwara

Mgbe ihe omume nke VT gasịrị, a na-ewere usoro iji gaa n'ihu ngosipụta.

• Ọgwụ eji ewere ọnụ nwere ike ịdị mkpa maka ọgwụgwọ ogologo oge. Otú ọ dị, ọgwụ ndị a nwere ike ịnwe mmetụta dị egwu. A na-eji ha eme ihe mgbe niile ka e mepụtara ọgwụgwọ ndị ọzọ.
• Enwere ike ime usoro iji bibie anụ ahụ obi nke na - akpata ọgbụgba obi na - adịghị mma (akpọrọ nsụ).
• Enwere ike ịtụnye defibrillator akụrụngwa akụrụngwa (ICD). Ọ bụ ngwaọrụ etinyere na-achọpụta ihe ọ bụla na-eyi ndụ egwu, ngwangwa obi ngwangwa. A na-akpọ obi mgbawa a na-adịghị mma arrhythmia. Ọ bụrụ na emee, ICD na-eziga ngwa ngwa eletriki n'ime obi ka ọ gbanwee ụda ahụ ka ọ daa. A na-akpọ nke a defibrillation.

Nsonaazụ na-adabere na ọnọdụ obi na mgbaàmà.

Ventricular tachycardia nwere ike ọ gaghị ebute mgbaàmà na ụfọdụ ndị mmadụ. Otú ọ dị, ọ nwere ike ịnwụ. Ọ bụ isi ihe na-akpata ọnwụ obi obi na mberede.

Gaa na ụlọ ihe mberede ma ọ bụ kpọọ nọmba ihe mberede mpaghara (dịka 911) ma ọ bụrụ na ị nwere ọsọsọ, adịghị mma usoro, ịda mba, ma ọ bụ nwee obi mgbu. Ihe ndị a niile nwere ike ịbụ ihe ịrịba ama nke tachycardia ventricular.

N'ọnọdụ ụfọdụ, enweghị ike igbochi nsogbu ahụ. N'ọnọdụ ndị ọzọ, enwere ike igbochi ya site na ịgwọ nsogbu obi yana izere ọgwụ ụfọdụ.
