A physiological signal monitoring method includes steps that involve: acquiring samples of at least one digitized physiological signal through the use of a device carried by a user； detecting events within the digitized physiological signal by means of the device and extracting characteristics of the detected events by means of the device； searching for an anomaly in the events and characteristics of the extracted events by means of the device； and, via an encrypted wireless link, transmitting the digitized physiological signal by means of the device to a server via a mobile terminal when an anomaly is detected. If an anomaly is not detected, the digitized physiological signal is deleted by the device.
