Radiofrequency Ablation tuaj yeem nres tachycardia?

Radiofrequency ablation (RFA) yog ib txoj kev cuam tshuam tsawg kawg nkaus. Ua ntej, lub plawv catheter electrode yog xa mus rau hauv lub plawv los ntawm puncture ntawm lub puab jugular los yog subclavian leeg thiab ob sab femoral leeg, thiab electrophysiological kev ntsuam xyuas yog ua los xyuas kom meej qhov kev kuaj mob thiab qhov chaw ntawm qhov txhab. Tom qab ntawd, ib qho tshwj xeeb ablation catheter raug xaiv kom ncav cuag qhov mob, thiab cov xov tooj cua tam sim no tau tawm. Thaum cov xov tooj cua tam sim no hu rau cov ntaub so ntswg myocardial, qhov kub thiab txias tau tsim, uas ua rau cov ntaub so ntswg myocardial hauv zos qhuav thiab necrotic, thiab cov ntaub so ntswg necrotic myocardial tsis ua lub luag haujlwm ntawm hluav taws xob conduction, yog li cov arrhythmia tuaj yeem kho. Kev ua haujlwm tau ua tiav thaum lub ablation tau lees paub los ntawm kev kuaj electrophysiological.

Radiofrequency radiofrequency tam sim no yog ib hom high-frequency alternating tam sim no nrog ntau zaus ntawm 100kHz ~ 3MHz. Radiofrequency ablation yog qhov tseem ceeb thermal puas. Cov ntaub so ntswg yog rhuab los ntawm lub tshav kub lub zog hloov los ntawm radiofrequency tam sim no, uas ua rau lub cev qhuav dej thiab qhuav, thiab ces ua rau coagulation necrosis. Thaum xub thawj, nws tsuas yog siv rau hauv cov tshuaj raws li high-frequency electroknife thiab electrocoagulator rau kev phais. Cov kev qhia ntawm radiofrequency catheter ablation rau tachycardia yog preexcitation syndrome thiab paroxysmal supraventricular tachycardia, ventricular tachycardia, atrial tachycardia, atrial flutter, thiab atrial fibrillation tshwm sim los ntawm ob txoj kev ntawm AV node. Yog tias nws yog sinus tachycardia tuaj yeem noj tshuaj, xws li propranolol, betaloc thiab lwm yam tshuaj tuaj yeem ua tau.
