SVC Syndrome lossis Wolff-Parkinson-White kab mob yog ib qho kev tsis sib haum xeeb hauv cov qauv ntawm lub plawv. Nyob rau hauv lub xub ntiag ntawm Kent lub nras - ib tug ntxiv kev taw qhia ntawm conduction ntawm lub atria mus rau lub ventricles, qhov no yog cov feem ntau syndrome ntawm kev ua kom thaum ntxov ntawm lub ventricles. Feem ntau cov neeg uas muaj tus mob no, uas muaj ntau dua rau cov txiv neej tshaj li poj niam, tsis muaj cov tsos mob ntawm tus kab mob plawv. Kent lub pob yog ib qho txawv txav ntawm myocardial fibers nyob rau hauv thaj tsam ntawm ib qho ntawm lub ventricles thiab sab laug atrium, uas yog ib qho tseem ceeb heev nyob rau hauv lub pathogenesis ntawm qhov mob sib txawv.
Nyob rau hauv qee cov neeg mob, ERW syndrome yuav tsis muaj cov tsos mob tshwm sim, tshwj tsis yog rau arrhythmia. Hauv ib nrab ntawm cov neeg mob uas muaj qhov tsis zoo no, kuaj pom paroxysmal tachyarrhythmias: atrial flutter thiab fibrillation, nrog rau supraventricular reciprocal arrhythmias. Cov kab mob no feem ntau nrog lub plawv mob xws li mitral valve prolapse, Ebstein anomaly, thiab hypertrophic cardiomyopathy.
Vim SVC syndrome tuaj yeem tshwm sim hauv daim ntawv latent, nws qhov kev kuaj pom tsuas yog ua tau nrog lub tshuab hluav taws xob ventricular. Nws txuas nroglub peev xwm txwv ntawm txoj hauv kev kom dhau impulses nyob rau hauv cov kev taw qhia antegrade. Nyob rau ntawm daim cardiogram thaum lub sij hawm lub sinus atherosclerosis, qhov tshwm sim ntawm kev ua kom ntxov ntxov ntawm lub ventricles yuav tsis tshwm sim nyob rau hauv txhua txoj kev. Tus kab mob SVC tau tshaj tawm muaj cov cim ECG hauv qab no: lub sijhawm luv luv P - R, P - Q; yoj D; expansion ntawm QRS complex; tachyarrhythmias.
SVC syndrome tuaj yeem kuaj tau txhua lub hnub nyoog, pib nrog tus menyuam yug tshiab. Nws qhov tshwm sim tuaj yeem ua kom yooj yim los ntawm txhua yam kab mob plawv uas tshwm sim nrog kev cuam tshuam ntawm AV conduction. Qhov tshwm sim tas li ntawm SVC tus kab mob, nrog rau kev tawm tsam ntawm arrhythmia, distorts intracardiac hemodynamics, uas inevitably ua rau expansion ntawm lub plawv chambers thiab ib tug txo nyob rau hauv lub peev xwm ntawm myocardium rau kev cog lus. Cov tsos mob ntawm tus kab mob no feem ntau nyob ntawm lub sijhawm thiab zaus ntawm tachyarrhythmias. Coronary tuag tshwm sim nyob rau hauv 4% ntawm cov neeg uas muaj tus kab mob no, feem ntau yog vim tuag arrhythmias.
SVC syndrome raug kho thiab kev tawm tsam raug tiv thaiv ntau txoj hauv kev: txhawm rau tiv thaiv kev tawm tsam ntawm tachycardia, siv tshuaj tiv thaiv arrhythmic; nyob rau hauv cov kev tshwm sim ntawm supraventricular tachycardia, dav hlau, intravenous tswj ntawm adenosine triphosphate yog siv, uas ua rau lub sij hawm luv luv ntawm lub plawv nres thiab nws rov pib dua ntxiv; Nyob rau hauv cov xwm txheej ntawm atrial fibrillation syndrome, ceev hluav taws xob defibrillation yog ua nrog kev puas tsuaj ntxiv ntawm txoj kev ntxiv.
Hma-Parkinson-White Syndrome yog kho nrog kev phais rau: cov ntsiab lusnquag tawm tsam ntawm atrial fibrillation; muaj kev tawm tsam ntawm tachyamitria nrog hemodynamic cuam tshuam; muaj kev tawm tsam tom qab kho antiarrhythmic; Nyob rau hauv rooj plaub ntawm contraindications rau kev kho mob mus sij hawm ntev.
Tus kab mob no tsis muaj dab tsi cuam tshuam nrog VPV-1A - hom khoom tawg mus txawv tebchaws siv nyob rau hauv qhov chaw tawg ntawm kev lag luam thiab mines. Cov keyboards no tau teeb tsa hauv thaj chaw muaj kev phom sij ntawm kev lag luam vim tias lawv cov qauv tsim muaj lub plhaub tawg, muaj lub cev thiab lub hau.
