Qhov txawv txav hauv kev sib kis ntawm hluav taws xob impulses: Wolff Parkinson White Syndrome
Wolff Parkinson White syndrome yog kab mob plawv vim qhov txawv txav ntawm cov hluav taws xob impulse ntawm atria thiab ventricles uas tuaj yeem ua rau tachyarrhythmias thiab palpitations.
Wolff-Parkinson-White syndrome manifests nws tus kheej nrog tachyarrhythmias nyob rau hauv uas tus neeg mob muaj ntau dhau lub plawv palpitation, nyob rau hauv tej rooj plaub txuam nrog fainting, kiv taub hau, mob hauv siab, ua pa nyuaj.
Nyob rau hauv cov tsos mob no, yuav muaj lub xub ntiag ntawm ib tug accessory bundle, Kent lub nras, uas txuas lub atrium thiab ventricle; nyob rau hauv txoj kev no thaum cov hluav taws xob impulse los ntawm lub sinus node dispersed nyob rau hauv lub atrial phab ntsa ua ntej mus txog lub atrioventricular node, Kent lub nras yuav khaws cov hluav taws xob signals ua rau lub ventricle daim ntawv cog lus ob peb milliseconds ua ntej tshaj li qub, tsim ventricular pre-excitation.
Lub tachycardia hauv Wolff-Parkinson-White syndrome tej zaum yuav yog atrioventricular reentrant, thaum nws yog tus cwj pwm los ntawm lub plawv dhia ceev ceev thiab lub tachycardia yog cais raws li supraventicular.
Atrial fibrillation yog ib yam kab mob uas tshwm sim los ntawm qhov ceev thiab tsis sib haum xeeb ntawm lub atria, tshwm sim los ntawm hluav taws xob impulses los ntawm myocardial cov leeg hlwb uas, nyob rau hauv ib txwm muaj mob, ua tsaug rau lub xub ntiag ntawm atrioventricular node, yog "filtered" thiab xa nyob rau hauv me me kom muaj nuj nqis ntawm lub plawv. ventricles ua rau cov no tsis cog lus sai li lub atria.
Lub xub ntiag ntawm cov pob khoom ntawm Kent es tsis txhob tso cai rau atrial impulses tuaj tos yam tsis muaj lub lim los ntawm kev xa hluav taws xob cov cim ntawm kev cog lus rau lub ventricles, ua rau cov zaus pib ntawm tachyarrhythmia uas tuaj yeem ua rau tuag taus.
Qhov cuam tshuam tshaj plaws yog cov tub ntxhais hluas noj qab haus huv, uas yog li ntawd muaj lub siab tsis tas yuav mob, uas yws ntawm ntu ntu ntawm tachycardia, thaum lwm tus lawv tsis ceeb toom txog qhov tsis xis nyob.
Kev kuaj mob Wolff Parkinson White Syndrome
Wolff Parkinson White tau kuaj pom nrog electrocardiogram.
Cov neeg uas cuam tshuam los ntawm cov kab mob no tuaj yeem ua rau lub plawv tuag sai, vim qhov kev nthuav tawm siab ceev ntawm atrial arrhythmia mus rau ventricles.
Wolff-Parkinson-White syndrome kho tau li cas?
Wolff Parkinson White cov neeg mob uas muaj tachyarrhythmias yuav tsum tau kho nrog:
- Vagal manoeuvres, txhawm rau txo lub plawv dhia, yog tias tus neeg mob raug qhia kom raug tuaj yeem ua qhov kev ua haujlwm no autonomously.
- Kev tswj hwm ntawm cov tshuaj uas thaiv kev ua los ntawm atrioventricular node los ntawm kev cuam tshuam ib qho ntawm cov caj npab arrhythmia. Cov tshuaj uas yuav tsum tau zam nyob rau hauv cov ntaub ntawv ntawm atrial fibrillation vim hais tias nyob rau hauv tej rooj plaub lawv yuav ua rau kom lub zaus ntawm conduction mus rau lub ventricles los ntawm cov accessory txoj kev uas ua rau ventricular fibrillation.
- Hluav taws xob cardioversion, ib tug txheej txheem nyob rau hauv uas hluav taws xob conduction ntawm lub plawv yog "rov qab" los ntawm lub defibrillator, nyob rau hauv thiaj li yuav restore lub plawv dhia.
Ablation yog suav tias yog qhov kev daws teeb meem tiag tiag yog tias muaj qhov tshwm sim tsis tu ncua.
Nws yog tus txheej txheem minimally invasive uas tso cai rau koj tshem tawm cov kab hluav taws xob tsis zoo, qhov no lawv yog Kent's bundles.
Nws pom qhov kev puas tsuaj ib nrab ntawm txoj hauv kev, los ntawm catheter ablation, piv txwv li kev xa tawm ntawm lub zog ntawm ib qho tshwj xeeb los ntawm lub catheter tso rau hauv lub plawv; nws ua tiav hauv ntau dua 95% ntawm cov neeg mob.
Ablation yog qhov tshwj xeeb tshaj yog rau cov neeg mob hluas uas tej zaum yuav raug yuam kom noj tshuaj antiarrhythmic rau lub neej.
