Abstract: A method and an apparatus are provided for transmitting information between a monitor and a remote computer. The monitor comprises a sensor coupled to a memory for logging data output by the sensor over time. The information transmission method includes the steps of interfacing the monitor to a base station for transmitting the information between the monitor and the base station, and transmitting the information between the base station and the remote computer by means of a text message or pager message. In this way, information can be transmitted in both directions, either from the monitor to the remote computer or from the remote computer to the monitor.

Abstract: The present invention pertains to a monitor that includes a cardiac sensor (36) responsive to a user's heart beat. The monitor includes a processor coupled to the sensor for generating heart-rate or other cardiac data. These data can be stored in a memory. The monitor is physically supported by and receives electrical signals from a single ECG electrode, and is coupled by an electrical lead to a second ECG electrode.
