A case of heart block treated with 1-cyclohexyl-2-methylaminopropane (benzedrex)

The patient reported apparently had fibrosis of the mitral annulus.Measures which increased the, auricular rate (exertion, nitroglycerin) caused the development of mild Adams-Stokes seizures with 2:1 heart block and faintness, but without syncope or convulsions.The attacks responded quickly to the inhalation of 1-cyclohexyl-2-methylaminopropane (Benzedrex) and have apparently been effectively prevented by the oral use of the same drug.
