Abstract: The invention relates an electric measuring arrangement (10) and to a measuring method both for monitoring a ground connection for an insulation monitoring device (4), which is connected to at least one active conductor (L1, L2) of an ungrounded power supply system (2) and a ground terminal (PE) of an electric installation (3), with an active loop measurement device (20), which is connectable between a ground-connection clamp (E) of the insulation monitoring device (4) and the ground terminal (PE) and has an independent excitation voltage source (UgEKE) for quantitatively determining a ground resistance (REKE) of the ground connection (6) between the insulation monitoring device (4) and the ground terminal (PE). Furthermore, the invention relates to an insulation monitoring device (30) having an electric measuring arrangement (10) according to the invention.

Abstract: This medicinal composition for the treatment and prevention of the symptoms of heart failure contains, by way of active principle, at least one compound chosen from 2-amino-1-(2,5-dimethoxyphenyl)-1-propanol (methoxamine) and its pharmaceutically acceptable salts, and it is presented in a form which can be administered by inhalation (aerosol or nebulizate).It was demonstrated, in particular, that the administration of methoxamine-HCl by inhalation, at a unit dosage of 10 mg, in the form of a 2% (w/v) solution in physiological saline, decreases airways resistance in subjects suffering from decompensated left ventricular failure, and increases the exertion tolerance of patients suffering from compensated left vetricular failure, whether the latter is of ischemic origin or otherwise.
