Ventricular tachycardia

Ventricular tachycardia (VT) inokurumidza kurova kwemoyo iyo inotangira mumakamuri epazasi emoyo (ventricles).

VT ndeyekupomba kweanopfuura zana kurova paminiti, iine angangoita matatu zvisina kujairika kurova kwemoyo mumutsara.

Mamiriro acho anogona kukura sekutanga kana kunonoka kusangana kwekurwadziwa kwemoyo. Izvo zvinogona zvakare kuitika kune vanhu vane:

• Cardiomyopathy
• Kutadza kwemoyo
• Kuvhiya kwemoyo
• Myocarditis
• Valvular chirwere chemoyo

VT inogona kuitika pasina chirwere chemwoyo.

Zvishoma zvemavara zvinogona kuumbika mumhasuru yema ventricles mazuva, mwedzi, kana makore mushure mekurwadziwa kwemoyo. Izvi zvinogona kutungamira kune ventricular tachycardia.

VT inogona kukonzerwa ne:

• Anti-arrhythmic zvinodhaka (zvinoshandiswa kurapa zvisina kujairika moyo rhythm)
• Shanduko muropa kemisitiri (senge yakaderera potasiamu nhanho)
• Shanduko mu pH (acid-base)
• Kushaya oxygen yakakwana

"Torsade de pointes" ndeimwe fomu yeVT. Inowanzoitika nekuda kwekuzvarwa kwechirwere chemwoyo kana kushandiswa kwemimwe mishonga.

Iwe unogona kuve nezviratidzo kana kurovera kwemoyo panguva yeVT episode kuchikurumidza kana kunogara kwenguva yakareba kupfuura masekondi mashoma. Zviratidzo zvinogona kusanganisira:

• Chifuva kusagadzikana (angina)
• Kufenda (syncope)
• Musoro wakareruka kana dzungu
• Kunzwa kwekunzwa moyo kurova (palpitations)
• Kufema kwekufema

Zviratidzo zvinogona kutanga nekumira kamwe kamwe. Mune zvimwe zviitiko, hapana zviratidzo.

Anopa hutano anotarisa:

• Kusapomba kwemhepo
• Kurasikirwa kwekuziva
• Kazhinji kana kuderera kweropa
• Kukurumidza kupisa

Miedzo inogona kushandiswa kuona ventricular tachycardia inosanganisira:

• Holter yekutarisa
• ECG
• Intracardiac electrophysiology kudzidza (EPS)
• Kutarisa kweRhythm neyakarekodwa rezimbo kana chishandiso

Iwe unogona zvakare kuve neropa chemistry uye kumwe kuyedza.

Kurapa kunoenderana nezviratidzo, uye nemhando yekusagadzikana kwemoyo.

Kana mumwe munhu ane VT ari mukutambudzika, vangangoda:

• CPR
• Cardioversion (magetsi kuvhunduka)
• Mishonga (senge lidocaine, procainamide, sotalol, kana amiodarone) inopihwa kuburikidza netsinga

Mushure mechikamu cheVT, matanho anotorwa kuenderera mberi zvikamu.

• Mishonga inotorwa nemuromo inogona kudikanwa pakurapwa kwenguva refu. Zvisinei, iyi mishonga inogona kuva nemigumisiro yakaipa. Ivo vari kushandiswa kashoma kazhinji sekumwe kurapwa kunogadzirwa.
• Maitiro ekuparadza moyo wemhasuru urikukonzera kurova kwemoyo zvisina kujairika (kunzi ablation) kunogona kuitwa.
• Inodyarwa cardioverter defibrillator (ICD) inogona kukurudzirwa. Icho chigadzirwa chakasimwa chinoona chero chinotyisa hupenyu, nekukurumidza kurova kwemoyo. Uku kurova kwemoyo kusingawanzo kunzi arrhythmia. Kana zvikaitika, iyo ICD inokurumidza kutumira kushamisika kwemagetsi kumoyo kuti ichinje mutinhimira kuti udzokere pane zvakajairwa. Izvi zvinonzi defibrillation.

Mhedzisiro yacho inoenderana nemamiriro emoyo uye zviratidzo.

Ventricular tachycardia inogona kusakonzera zviratidzo kune vamwe vanhu. Zvisinei, zvinogona kuva zvinouraya. Icho chikonzero chikuru chekufa kamwe kamwe kwemoyo.

Enda kuimba yekukurumidzira kana kufonera iyo yemuno emergency emergency (yakadai se911) kana iwe uchikurumidza, zvisina kujairika kupomba, kupera simba, kana kurwadziwa muchipfuva Zvese izvi zvinogona kuve zviratidzo zve ventricular tachycardia.

Mune zvimwe zviitiko, kusagadzikana hakugone kudzivirirwa. Mune zvimwe zviitiko, inogona kudzivirirwa nekurapa matambudziko emoyo uye kudzivirira mimwe mishonga.

• Inodyara cardioverter defibrillator - kubuda

• Inodyara cardioverter-defibrillator
• Inodyarwa yemoyo defibrillator
