The cudurada wadnaha aasaasiga ah, taas oo loo isticmaalo blockers beta - cudurada wadnaha ischaemic. hab ay of tallaabo of walxaha waa Go'doominta adrenergic beta, taasoo keentay in hoos u dhac hawlaha qalbigiisa, contractility, tabinta, excitability, automatism. Natiijadu waxay tahay hoos u of wadnaha, taas oo ah hoos u dhac in garaaca wadnaha, stroke mugga iyo wax soo saarka wadnaha. baahida oxygen myocardial infarction waxa aad u yaraynaya, iyo sidaas hubisaa hortagga wax ku ool ah weeraro angina. Daroogada ee kooxda taas oo yaraynaysa khatarta dhimashada lama filaan ah in bukaanka soo gaaray Wadnaxanuun myocardial.

Waayo, cupping tachyarrhythmias waxaa sidoo kale loo isticmaalaa adrenoblokatorry beta. Hoos u dhaca heerka garaaca wadnaha, gaabis ah tabinta atrioventricular sharxayaa saamaynta ku daweynta. A saamayn badan sameysa ee daroogada ayaa lagu arkay joogitaanka garaaca wadne.

walxaha, daawooyinka kaas oo ay leeyihiin ficil ku furid beta ka tirsan mid ka mid ah shan fasalada wakiilada antihypertensive.
