Khoom piav qhia
Adenosineyog ib qho purine nucleoside compound tsim los ntawm kev sib txuas N-9 ntawm adenine rau C-1 ntawm D-ribose ntawm -glycosidic daim ntawv cog lus. Daim ntawv tshuaj yog C10H13N₅O₄. Daim ntawv phosphate yog adenosine. Adenosine ua lub luag haujlwm tseem ceeb hauv biochemistry, suav nrog kev hloov pauv hluav taws xob hauv daim ntawv ntawm adenosine triphosphate (ATP) lossis adenosine diphosphate (ADP), thiab teeb liab hauv daim ntawv ntawm cyclic adenosine monophosphate (cAMP). D-adenine Nucleosid yog glycosylamine molecule uas muaj nucleic acid hauv paus ntxiv rau Ribose lossis Deoxyribose. Cov hauv paus muaj xws li Purine thiab Pyrimidine. Purines, suav nrog Guanine thiab Adenine, thiab pyrimidines, suav nrog Cytosine, Thymine thiab Uracil, yog tsim nyob rau hauv daim ntawv ntawm -N glycosidic bonds ntawm ribose thiab nucleic acid bases.
Adenosineyog lub ntuj nucleotide, ib qho khoom nruab nrab ntawm lub cev metabolism, thiab ib qho ntawm cov khoom tseem ceeb hauv lub cev. Nws ua haujlwm los ntawm kev ua kom adenosine receptors (A receptors). Hauv atria, sinoatrial node, thiab atV node, adenosine activates G protein-coupled potassium raws los ntawm kev khi rau A receptor, nce K + tawm, thiab txo cov membrane hyperpolarization thiab tsis siv neeg. Nws kuj tseem tuaj yeem ua rau nce qib ntawm cGMP, ncua ERP ntawm atrioventricular node thiab ua kom qis qis, inhibit qhov ntxov thiab lig depolarization tshwm sim los ntawm sympathetic paj hlwb lossis isoproterenol, thiab ua lub luag haujlwm antiarrhythmic.

Amiodarone thiab adenosine yog dab tsi?
Amiodarone thiab adenosine ua lub luag haujlwm hauv kev kho SVT, muab txoj hauv kev los kho lub plawv zoo li qub thiab txhim kho tag nrho cov kev mob tshwm sim rau cov tib neeg cuam tshuam los ntawm tus mob no.
Dab tsi yog qhov txawv ntawm adenosine thiab atropine?
Txawm hais tias ob qho tib si atropine thiab adenosine yog antiarrhythmics, lawv cov lus qhia txawv heev. Atropine, ib qho anticholinergic, yog cov tshuaj xaiv rau cov tsos mob bradycardia. Adenosine, ib qho endogenous nucleoside, yog siv los kho ntau hom kev nqaim-complex paroxysmal supraventricular tachycardia.
Dab tsi yog adenosine siv rau?
Adenosine yog siv los kho qee yam ntawm lub plawv dhia tsis xwm yeem. Nws kuj tuaj yeem siv tau thaum kuaj kev ntxhov siab los kuaj xyuas qee yam teeb meem hauv plawv, xws li kab mob plawv, plawv tsis ua hauj lwm, lossis teeb meem plawv.
