Arrhythmia vs Dysrhythmia
Ob leeg arrhythmia thiab dysrhythmia txhais tau tib yam. Arrhythmia txhais tau tias tsis muaj kev sib dhos tsis tu ncua thiab dysrhythmia txhais tau hais tias txawv txav. Kev cuam tshuam ntawm lub plawv atherosclerosis los yog arrhythmias yog tshwm sim nyob rau hauv tib neeg, feem ntau benign, thiab feem ntau cuam tshuam. Txawm li cas los xij, lawv tuaj yeem hnyav qee zaum ua rau mob plawv. Kab lus no yuav ua tib zoo saib ntawm arrhythmia, qhia txog ntau hom arrhythmia (xws li mob plawv arrhythmia, sinus arrhythmia, ventricular arrhythmia), cov tsos mob thiab kev kuaj mob ntawm arrhythmias, thiab cov kev kho mob uas lawv xav tau.
Causes of arrhythmia: Feem ntau ua rau mob plawv arrhythmias (cardiac dysrhythmias) yog myocardial infarction (heart attack), kab mob plawv, sab laug ventricular aneurysm (abnormal dilatation), mitral valve kab mob, cardiomyopathy (lub plawv mob), myocardial abnormality., pericarditis, thiab txawv txav txoj hauv kev ntawm lub plawv. Feem ntau tsis mob plawv ua rau arrhythmia yog caffeine, haus luam yeeb, cawv, mob ntsws, tshuaj (xws li digoxin, beta blockers, L dopa, thiab tricyclic), thiab metabolic imbalances (potassium, calcium, magnesium, qib carbon dioxide siab, thyroid kab mob)..
Cov tsos mob Arrhythmia: Cov neeg mob arrhythmia tshwm sim nrog mob hauv siab, palpitations, fainting attack, ntshav siab thiab sau cov kua hauv lub ntsws. Qee cov arrhythmias yog asymptomatic thiab tshwm sim. Palpitations tej zaum yuav tsis tu ncua, tsis xwm yeem, nrawm, lossis qeeb. Lub sijhawm ntawm cov tsos mob arrhythmias txawv raws li qhov ua rau. Keeb kwm tshuaj, tsev neeg keeb kwm ntawm kab mob plawv, thiab keeb kwm kho mob yav dhau los tseem ceeb heev hauv kev tshawb nrhiav.
Kev kuaj mob arrhythmias xav tau cov ntshav suav tag nrho, ntshav urea, thiab electrolytes, ntshav qabzib, ntshav calcium, magnesium, thyroid stimulating hormone, thiab electrocardiogram. Electrocardiogram tuaj yeem pom cov kev hloov pauv hauv ischemic, atrial fibrillation, luv PR luv (Hma-Parkinson-White syndrome), ntev QT ntu (metabolic), thiab U tsis (tsis tshua muaj poov tshuaj). Echocardiogram kuj tseem tuaj yeem pom cov tsos mob ntawm cov kab mob plawv. Kev tshawb nrhiav ntxiv tuaj yeem suav nrog kev tawm dag zog ECG, mob plawv catheterization thiab kev tshawb fawb electrophysiological.
Kev kho rau arrhythmias txawv raws li hom arrhythmia. Yog tias ECG zoo li qub thaum ua palpitation, tus neeg mob yuav tsum tsis muaj kev cuam tshuam.
Bradycardia arrhythmia yog txhais tias lub plawv dhia qeeb dua 50 tus neeg ntaus ib feeb. Yog tias tus neeg mob asymptomatic thiab tus nqi siab dua 40 bpm, nws yuav tsum tsis muaj kev cuam tshuam. Cov tshuaj Causative thiab kho mob (xws li hypothyroidism) yuav tsum tau kho. Atropine, isoprenalin, thiab pacing yog paub txoj kev kho mob.
Sick sinus syndrome yog vim muaj hluav taws xob txawv txav ntawm SA node. Cov neeg mob cov tsos mob xav tau pacing.
Supraventricular tachycardia arrhythmia nta P nthwv dej, nqaim QRS complex, thiab lub plawv dhia siab tshaj 100bpm. Carotid massage, verapamil, adenosine, amiodarone, thiab DC shock yuav raug siv los kho SVT. Atrial fibrillation thiab flutter tuaj yeem yog qhov kev tshawb pom. Atrial fibrillation nta QRS complexes thiab tsis muaj P nthwv dej. Atrial flutter tus nqi feem ntau yog nyob ib ncig ntawm 300 bmp, tab sis ventricular tus nqi yog li 150 bpm. Digoxin tuaj yeem tswj cov hlab ntshav. Verapamil, beta blockers, thiab amiodarone yog lwm txoj hauv kev zoo. DC shock yog xav tau yog tias lub plawv ua haujlwm raug cuam tshuam.
Ventricular tachycardia arrhythmia nta dav QRS complexes hauv ECG. Ventricular tachycardia yog ib qho kev poob siab. Amiodarone thiab DC shock tuaj yeem siv los kho VT.
Raws li kev ntsuas zaum kawg, siv lub tshuab pacemaker mus tas li txhawm rau txhawm rau txhawm rau arrhythmias. Tsis siv neeg implanted defibrillators uas rov pib lub plawv hluav taws xob ua haujlwm thaum lub plawv nres cawm txoj sia.
