Abstract
A programmable interface for typical Holter machine for recording a physiological signal, notably of cardiac activity. This apparatus (10) comprises the normal plugs (14) for connection to external electrodes and a processing circuit (20) for acquiring and recording the physiological signal, and a programmable interface comprising: at least one voltage supply plug (and preferably two supply plugs V+, V-), at least one ground plug, at least one digital plug (preferably two or more digital plugs D1, D2), cooperating with the processing circuit (20), at least one analog/digital mixed plug (A/D3), on the one hand connected to an analog signal input of the machine, and on the other hand cooperating with the aforementioned processor circuit, and a logic circuit (28) for programming the interface to transfer signals through the plugs of the interface.
