Paroxysmal tachycardia - qhov ntse thiab nrawm nrawm ntawm lub plawv dhia. Nws cuam tshuam nrog kev cuam tshuam ntawm kev tsom xam ectopic, uas ua rau muaj kev cuam tshuam rau myocardial contraction.
Cas thiab hom
Paroxysmal tachycardia tshwm sim nrog lub plawv nres, myocarditis, atherosclerotic cardiosclerosis. Nyob rau hauv etiology ntawm txoj kev loj hlob ntawm no pathology, cardiomyopathies thiab kub siab yog txawv. Tsis tas li ntawd, paroxysmal tachycardias tsim tsis muaj cov organic puas tsuaj rau myocardium. Yog li, lawv tuaj yeem raug soj ntsuam nrog neurocirculatory dystonia, kev tsim txom ntawm kas fes lossis cawv, nrog cov tshuaj hormonal.
Cov kab mob hauv qab no ntawm lub plawv dhia tsis zoo yog qhov txawv:
- supraventricular - tus cwj pwm los ntawm kev tsim ntawm ectopic tsom hauv lub atrioventricular node lossis hauv atria (paroxysmal atrial tachycardia);
- yog tias muaj kev cuam tshuam ntxiv los ntawm lub ventricles, qhov no qhia txog kev txhim kho ntawm lub plawv ventricular paroxysmal.
Kev kho mob tshwm sim
Ib qho kev tawm tsam ntawm tachycardia tshwm sim thiab ploj tam sim ntawd. Nws kavlos ntawm ob peb feeb mus rau ob peb hnub. Tus neeg mob tau ntsib kev thawb tam sim ntawd hauv cheeb tsam ntawm lub plawv, uas hloov mus rau hauv lub plawv dhia thiab tsis xis nyob hauv siab. Qee zaum cov neeg mob qhia qhov mob hauv lub plawv thiab ua tsis taus pa. Feem ntau, paroxysmal tachycardias yog nrog los ntawm kev qaug zog thiab kiv taub hau. Qee lub sij hawm muaj ntshav siab nce ntxiv, xav tias tsis muaj cua lossis coma hauv caj pas. Tej zaum yuav tso zis ntau dhau tom qab qhov kev tawm tsam xaus.
Tsawg zaus, nrog paroxysmal tachycardia, cov tsos mob ntawm lub paj hlwb nyob rau hauv daim ntawv ntawm aphasia thiab hemiparesis tau pom. Kuj tseem muaj qhov tshwm sim ntawm autonomic dysfunction. Cov neeg mob yws yws ntawm xeev siab thiab tawm hws, kub subfebrile thiab flatulence. Tom qab qhov kev tawm tsam, polyuria yog yam ntxwv, cov zis yog tawm ntawm qhov ntom ntom. Protracted paroxysmal tachycardias yog tshwm sim los ntawm kev txo cov ntshav siab, tsis muaj zog thiab tsis nco qab.
Kev kho mob
Nrog paroxysmal tachycardia, koj tuaj yeem sim tshem tawm qhov kev tawm tsam uas siv txoj hauv kev reflex. Yog li, koj tuaj yeem zaws lub carotid sinus, tuav koj txhais tes thiab tso koj lub ntsej muag hauv dej txias rau 30 vib nas this, ua kom lub zais pa lossis nias koj lub qhov muag nrog lub zog nruab nrab.
Kev kho tshuaj muaj xws li noj tshuaj tshwj xeeb. Cov tshuaj kws tshaj lij tshaj plaws yog Novocainamide, Propafenone, Amiodarone, Verapamil. Nrog rau qhov tsis muaj txiaj ntsig ntawm kev kho tshuaj pharmacological, lawv siv rau hluav taws xob defibrillation, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas tshwm simcoronary insufficiency lossis arrhythmic collapse.
Thaum mob hnyav paroxysmal tachycardia tshwm sim, kev phais siv tau zoo vim tias nws cuam tshuam nrog kev sib cais lossis tshem tawm ncaj qha ntawm ectopic lesion hauv plawv. Kev kho mob phais kuj tseem qhia tau rau cov neeg mob rov qab tsis tu ncua thiab tsis muaj txiaj ntsig ntawm cov tshuaj tiv thaiv arrhythmic.
