I-ventricular tachycardia: kuyini, izimpawu nokwelashwa

I-Ventricular tachycardia wuhlobo lwe-arrhythmia olunenhliziyo ephezulu, enezinhliziyo ezingaphezu kwezingu-120 ngomzuzu. Kwenzeka engxenyeni engezansi yenhliziyo, futhi kungaphazamisa ikhono lokumpompa igazi emzimbeni, izimpawu zifaka ukuphefumula, ukuqina esifubeni futhi umuntu angaquleka ngisho.

Lolu shintsho lungenzeka kubantu ababonakala bephilile bengenazo izimpawu futhi luvame ukuba nobungozi, yize lungabangelwa nokugula okungathi sína, okungaholela nasekufeni.

I-ventricular tachycardia ingahlukaniswa njenge:

• Akusekelwa: lapho ima yodwa ngemizuzwana engaphansi kwengu-30
• Kusekelwa: okuyilapho inhliziyo ifinyelela ukushaya okungaphezulu kuka-120 ngomzuzu ngaphezu kwemizuzwana engama-30
• I-hemodynamically ayizinzile: lapho kunokukhubazeka kwe-hemodynamic futhi kudinga ukwelashwa ngokushesha
• Ongapheli: lokho kugcinwa ngokuqhubekayo futhi kubhuka ngokushesha
• Isiphepho sikagesi: lapho zenzeka amahlandla ama-3 noma ama-4 kungakapheli amahora angama-24
• I-Monomorphic: lapho kunoshintsho olufanayo lwe-QRS ngokushaya ngakunye
• Polymorphic: lapho i-QRS ishintsha ngokushaya ngakunye
• I-Pleomorphic: lapho kunama-QRS angaphezu kwe-1 ngesikhathi sesiqephu
• Ama-Torsades de pointes: lapho kune-QT ende futhi kujikelezwa iziqongo ze-QRS
• Ukungena kabusha kwesibazi: lapho kukhona isibazi enhliziyweni
• Okugxile: lapho iqala endaweni eyodwa futhi isakazeke ezindaweni ezahlukahlukene
• Idiopathic: lapho singekho isifo senhliziyo esihambisanayo

I-cardiologist ingazi ukuthi yiziphi izici ngemuva kokwenza i-electrocardiogram.

Izimpawu ze-tachycardia ye-ventricular

Izimpawu ze-tachycardia ye-ventricular zingafaka:

• Ukushaya kwenhliziyo okusheshayo okungazwakala esifubeni;
• Ishayela esheshayo;
• Kungaba nokwanda kwezinga lokuphefumula;
• Ukuphefumula kungaba khona;
• Ukungaphatheki kahle kwesifuba;
• Isiyezi kanye / noma ukuquleka.

Kwesinye isikhathi, i-ventricular tachycardia ibangela izimpawu ezimbalwa, noma kumaza afinyelela kuma-200 amabhithi ngomzuzu, kepha kusengozini enkulu. Ukuxilongwa kwenziwa ngudokotela wezinhliziyo osuselwa ku-electrocardiogram, echocardiogram, cardiac magnetic resonance noma inhliziyo catheterization test.

Izinketho zokwelashwa

Inhloso yokwelashwa ukubuyisela ukushaya kwenhliziyo yakho kokujwayelekile, okungatholakala nge-defibrillator esibhedlela. Ngaphezu kwalokho, ngemuva kokulawula ukushaya kwenhliziyo kubalulekile ukuvimbela iziqephu ezizayo. Ngakho-ke, ukwelashwa kungenziwa nge:

Ukuphefumula kwenhliziyo:iqukethe "ukushaqeka kukagesi" esifubeni sesiguli ngokusebenzisa i-defibrillator esibhedlela. Isiguli sithola umuthi wokulala ngesikhathi senqubo, ngakho-ke, abuzwa buhlungu, okuyinqubo esheshayo nephephile.

Ukusetshenziswa kwemithi: kukhonjisiwe kubantu abangazibonisi izimpawu, kepha okungasebenzi njengokuphefumula kwenhliziyo, futhi amathuba okuba nemiphumela engemihle makhulu.

Ukufakwa kwe-ICD: I-ICD iyithuluzi le-cardiodefibrillator elitshalwayo, elifana ne-pacemaker, elikhonjiswa kubantu abasethubeni eliphezulu lokwethula iziqephu ezintsha ze-ventricular tachycardia.

Ukuchithwa kwezindawo ezincane ezingavamile ze-ventricular:ngokusebenzisa ipayipi elifakwe enhliziyweni noma ukuhlinzwa kwenhliziyo evulekile.

Izinkinga zihlobene nokuhluleka kwenhliziyo, ukuquleka nokufa okungazelelwe.

Izimbangela ze-tachycardia ye-ventricular

Ezinye izimo ezingadala i-ventricular tachycardia zifaka phakathi isifo senhliziyo, imiphumela emibi yomunye umuthi, i-sarcoidosis nokusetshenziswa kwezidakamizwa ezingekho emthethweni, kepha kunezimo ezithile lapho imbangela ingatholakali.
