Qhov sib txawv tseem ceeb ntawm polymorphic thiab monomorphic ventricular tachycardia yog tias polymorphic ventricular tachycardia yog ib hom mob plawv dhia ceev ceev nrog kev sib txawv tsis tu ncua QRS complex morphology nyob rau hauv ib qho chaw electrocardiogram, thaum monomorphic ventricular tachycardia yog ib hom ntawm lub plawv dhia ceev ceev. tus nqi nrog QRS complexes nyob rau hauv txhua cov hlau lead hauv electrocardiogram nto.
Ventricular tachycardia (VT) yog hais txog lub plawv dhia siab dua 100 neeg ntaus ib feeb, uas feem ntau pib hauv lub ventricles. Nws tuaj yeem muab faib ua ntau yam raws li lub sijhawm, morphology, thiab cov nyhuv hemodynamic. Piv txwv li, muaj ob hom VT raws sijhawm raws li kev txhawb nqa thiab tsis txhawb nqa. Sustained VT kav ntev dua 30 vib nas this, hos VT tsis txhawb nqa ntev dua 30 vib nas this. Ntxiv mus, raws li morphology, ventricular tachycardia tuaj yeem raug cais raws li polymorphic ventricular tachycardia thiab monomorphic ventricular tachycardia.
YPolymorphic Ventricular Tachycardia yog dab tsi?
Polymorphic ventricular tachycardia (PVT) yog ib hom ntawm lub plawv dhia ceev ceev nrog kev sib txawv tsis tu ncua QRS complex morphology hauv electrocardiogram. Yog li ntawd, QRS complexes txawv nyob rau hauv amplitude, axis, thiab ntev nyob rau hauv PVT. Thaum ventricular tachycardia tshwm sim nyob rau hauv ntau qhov chaw nyob ib ncig ntawm lub ventricle, nws yog hu ua polymorphic ventricular tachycardia. Torsade de Pointes yog ib qho piv txwv nrov heev ntawm lub neej-kev hem thawj polymorphic ventricular tachycardia. Nws tseem hu ua ventricular tachycardia (tachyarrhythmia), nrog rau kev hloov pauv sai thiab lub plawv dhia. Tus nqi tuaj yeem hloov ntawm 150 mus rau 250 neeg ntaus ib feeb hauv polymorphic ventricular tachycardia. Hom tachycardia no tuaj yeem hloov mus rau qhov qub lossis nce mus rau hauv ventricular fibrillation.
Daim duab 01: Polymorphic Ventricular Tachycardia
Ventricular fibrillation yog hom mob hnyav dua ntawm ventricular tachycardia. Nyob rau hauv cov ntaub ntawv no, muaj ib tug ceev thiab sporadic ntaus. Qhov no ua rau hemodynamic vau tam sim ntawd. Yog li ntawd, kev tuag yuav zoo li nyob rau hauv feeb ntawm ventricular fibrillation tshwj tsis yog tias cov kev pab txhawb nqa lub plawv tau muab tam sim ntawd. Polymorphic ventricular tachycardia yog qhov feem ntau ntawm ventricular tachycardia nyob rau hauv qhov chaw kho mob tseem ceeb. Lub xub ntiag ntawm polymorphic ventricular tachycardia tuaj yeem yog vim muaj kab mob plawv hnyav xws li myocardial ischemia, cardiomyopathies lossis genetic arrhythmia syndrome. Tsis tas li ntawd, polymorphic ventricular tachycardia yog qhov zoo tshaj plaws kho nrog cov tshuaj magnesium, tshem tawm cov tshuaj txhaum cai lossis kho cov poov tshuaj thiab calcium imbalances.
Monomorphic Ventricular tachycardia yog dab tsi?
Monomorphic ventricular tachycardia (MVT) yog ib hom mob plawv dhia ceev uas sau cov QRS zoo tib yam hauv ib qho electrocardiogram. Yog li ntawd, QRS complexes yog uniform hauv MVT. Thaum ventricular tachycardia pheej rov tshwm sim nyob rau tib qhov chaw ntawm lub ventricle, nws raug cais raws li monomorphic ventricular tachycardia. MVT yog ib qho yooj yim, ceev lub plawv dhia nrog ib qho ectopic ntaus los ntawm lub ventricle. Cov neeg mob uas muaj kab mob hauv lub plawv feem ntau pom muaj monomorphic ventricular tachycardia. Feem ntau muaj ib cheeb tsam ntawm kev ua qeeb qeeb uas yog vim muaj caws pliav lossis fibrillar disarray nyob rau hauv lub ventricular tachycardia.
Daim duab 02: Monomorphic Ventricular Tachycardia
Ua rau monomorphic ventricular tachycardia suav nrog ua ntej infarction, ib qho kev cardiomyopathy thawj zaug, phais caws pliav, hypertrophy, thiab cov leeg nqaij degeneration. Ntxiv mus, tus neeg mob tsis ruaj khov nrog monomorphic ventricular tachycardia yuav tsum tau kho tam sim nrog synchronized ncaj qha cardioversion tam sim no. Tsis tas li ntawd, cov tshuaj antiarrhythmic xws li amiodarone, beta-blockers, propranolol, sedation, thiab catheter ablation kuj tau siv los ua kev kho mob rau monomorphic ventricular tachycardia
Similarities Ntawm Polymorphic thiab Monomorphic Ventricular tachycardia
- Polymorphic thiab monomorphic ventricular tachycardia yog ob hom ventricular tachycardia raws li morphology.
- Ob qho xwm txheej pib hauv lub ventricles.
- Cov xwm txheej no qhia tias lub plawv dhia ceev tsis zoo.
- Lawv tuaj yeem yog vim muaj kab mob hauv lub siab.
- Lawv kho tau nrog tshuaj tiv thaiv kab mob.
Qhov txawv ntawm Polymorphic thiab Monomorphic Ventricular tachycardia
Polymorphic ventricular tachycardia yog ib hom ntawm lub plawv dhia ceev ceev uas muaj ntau QRS complexes hauv electrocardiograms, thaum monomorphic ventricular tachycardia yog ib hom ntawm lub plawv dhia ceev uas muaj cov QRS complexes nyob rau hauv txhua cov hlau lead hauv electrocardiograms. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm polymorphic thiab monomorphic ventricular tachycardia. Tsis tas li ntawd, ventricular tachycardia tshwm sim nyob rau hauv ntau qhov chaw nyob ib ncig ntawm lub ventricle nyob rau hauv PVT, thaum ventricular tachycardia pheej rov tshwm sim nyob rau hauv tib qhov chaw ntawm lub ventricle nyob rau hauv MVT.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm polymorphic thiab monomorphic tachycardia hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Polymorphic vs Monomorphic Ventricular Tachycardia
Ventricular tachycardia yog hais txog lub plawv dhia ntau dua 100 tus neeg ntaus ib feeb uas feem ntau pib hauv lub ventricles. Raws li morphology, ventricular tachycardia tuaj yeem faib ua polymorphic ventricular tachycardia thiab monomorphic ventricular tachycardia. Hauv polymorphic ventricular tachycardia, QRS complexes qhia qhov sib txawv morphology hauv ECG. Hauv monomorphic ventricular tachycardia, QRS complexes zoo ib yam hauv ECG. Ntxiv mus, ventricular tachycardia tshwm sim nyob rau hauv ntau qhov chaw nyob ib ncig ntawm lub ventricle nyob rau hauv PVT, thaum lub ventricular tachycardia originates nyob rau tib qhov chaw ntawm lub ventricle nyob rau hauv MVT. Yog li, qhov no qhia txog qhov sib txawv ntawm polymorphic thiab monomorphic ventricular tachycardia.
