title: Inhaler syncope.
abstract: Syncope can result from certain activities that trigger an exaggerated physiological response in susceptible individuals; examples include cough, laugh, and micturition syncope. We report a novel cause for syncope, that due to reflex bradycardia and asystole produced by the use of asthma inhalers. We discuss the possible mechanisms for this effect and briefly review other breathing-related causes of bradycardia.
