Abstract: A method monitors cardiac arrest during physical exercise and consequently activates a rescue request. The method continuously measures a user's heart rate to determine a heart rate in a sequence of predetermined time intervals, by a heart rate measurement device worn by the user; then, generating a signal representative of the heart rate detected in each interval. A motion sensor detects a user's motion condition and generates a motion signal representative of the motion detected. A portable processor receives the heart rate signal and communicates with the heart rate measurement device and with the motion sensor; then processes the signal representative of heart rate, to recognize a possible cardiac arrest condition. The processor processes the motion signal to detect a possible stillness condition. The processor activates a rescue request if both a cardiac arrest condition and a stillness condition have been recognized. A system executes the method.

Abstract: An electro catheter for neurostimulation includes a stimulation end of essentially helical shape, suited to be wrapped around a nerve. The stimulation end is deformable, meaning that it has a helical shape that can be modified in diameter and/or pitch, according to the dimensions of the nerve to be wrapped, and can be modified even to the point of assuming an essentially rectilinear linear shape according to the profile of the nerve, so that it is suited to be positioned in proximity to the nerve, along its profile.
