I-tachycardia evundlile

I-Ventricular tachycardia (VT) ukushaya kwenhliziyo okusheshayo okuqala emakamelweni aphansi enhliziyo (ama-ventricles).

I-VT isilinganiso sokushaya okungaphezu kwezi-100 ngomzuzu, okungenani ukushaya kwenhliziyo okungajwayelekile oku-3 kulandelana.

Isimo singakhula njengesinkinga sokuqala noma sekwephuzile sokuhlaselwa yinhliziyo. Kungenzeka futhi kubantu abane:

• I-Cardiomyopathy
• Ukwehluleka kwenhliziyo
• Ukuhlinzwa kwenhliziyo
• I-myocarditis
• Isifo senhliziyo seValvular

I-VT ingenzeka ngaphandle kwesifo senhliziyo.

Izicubu ezibomvu zingakheka emisipheni yezinsuku ze-ventricles, izinyanga, noma iminyaka ngemuva kokuhlaselwa yinhliziyo. Lokhu kungaholela ku-tachycardia ye-ventricular.

I-VT nayo ingabangelwa:

• Izidakamizwa ezilwa nokuhleleka (ezisetshenziselwa ukwelapha isigqi senhliziyo esingajwayelekile)
• Izinguquko kumakhemikhali egazi (njengezinga eliphansi le-potassium)
• Izinguquko ku-pH (i-acid-base)
• Ukuntuleka komoya-mpilo owenele

I- "Torsade de pointes" iyindlela ethile ye-VT. Imvamisa kungenxa yesifo senhliziyo esizelwe noma ukusetshenziswa kwemithi ethile.

Ungaba nezimpawu uma isilinganiso senhliziyo ngesikhathi sesiqephu se-VT sishesha kakhulu noma sihlala isikhathi eside kunemizuzwana embalwa. Izimpawu zingafaka:

• Ukungakhululeki kwesifuba (angina)
• Ukuquleka (i-syncope)
• Inwele elikhanyayo noma isiyezi
• Ukuzwa kokuzwa ukushaya kwenhliziyo (ukushaya kwenhliziyo)
• Ukuphelelwa umoya

Izimpawu zingaqala futhi zime ngokungazelelwe. Kwezinye izimo, azikho izimpawu.

Umhlinzeki wezokunakekelwa kwempilo uzobheka:

• I-pulse engekho
• Ukulahlekelwa ukwazi
• Umfutho wegazi ojwayelekile noma ophansi
• Ukushaya ngamandla okusheshayo

Ukuhlolwa okungasetshenziswa ukuthola i-tachycardia ye-ventricular kufaka:

• Ukuqapha kweHolter
• ECG
• Isifundo se-Intracardiac electrophysiology (EPS)
• Ukuqapha isigqi ngesirekhoda se-loop noma idivayisi

Ungase futhi ube namakhemikhali egazi nokunye ukuhlolwa.

Ukwelashwa kuya ngezimpawu, kanye nohlobo lwesifo senhliziyo.

Uma umuntu one-VT esosizini, angadinga:

• CPR
• I-Cardioversion (ukushaqeka kukagesi)
• Imithi (efana ne-lidocaine, i-procainamide, i-sotalol, noma i-amiodarone) enikezwa ngomthambo

Ngemuva kwesiqephu se-VT, kuthathwa izinyathelo zokuqhubeka kweziqephu.

• Imithi ethathwe ngomlomo ingadingeka ekwelapheni isikhathi eside. Kodwa-ke, le mithi ingaba nemiphumela emibi kakhulu. Zisetshenziswa kaningi njengoba ezinye izindlela zokwelapha zenziwa.
• Inqubo yokubhubhisa izicubu zenhliziyo ezibangela ukushaya kwenhliziyo okungavamile (okubizwa nge-ablation) ingenziwa.
• Kunganconywa i-cardioverter defibrillator (ICD) egxilile. It is a into efakiwe ethola noma yikuphi ukushaya kwenhliziyo okusongela impilo, okusheshayo. Lokhu kushaya kwenhliziyo okungavamile kubizwa ngokuthi i-arrhythmia. Uma kwenzeka, i-ICD isheshe ithumele ukushaqeka kukagesi enhliziyweni ukushintsha isigqi sibuyele kokujwayelekile. Lokhu kubizwa ngokuthi yi-defibrillation.

Umphumela uncike esimweni senhliziyo nasezimpawu.

I-ventricular tachycardia kungenzeka ingabangeli izimpawu kwabanye abantu. Noma kunjalo, kungaba yingozi. Kuyimbangela enkulu yokufa okungazelelwe kwenhliziyo.

Iya egumbini labezimo eziphuthumayo noma ushayele inombolo yendawo ephuthumayo (efana ne-911) uma unesisindo esisheshayo, esingajwayelekile, uqulekile noma unezinhlungu esifubeni. Zonke lezi zingaba yizimpawu ze-ventricular tachycardia.

Kwezinye izimo, lesi sifo asikwazi ukuvinjelwa. Kwezinye izimo, kungavinjelwa ngokwelapha izinkinga zenhliziyo nokugwema imithi ethile.
