An ambulatory rescalable encoding monitor recorder and a method for monitor recorder-implemented rescalable encoding are provided. An encoding table comprising a plurality of codes and a range of electrocardiographic values associated with each of the codes is maintained. Electrocardiographic values are sensed by the monitor recorder during a sequence of temporal windows. The values are processed, the processing including: calculating a difference between a maximum one and a minimum one of the values in each of the windows; comparing each of the differences to an at least one threshold; based on the comparison of the difference for at least one of the windows, adjusting table; encoding each of the values with one of the codes using the table, wherein the adjusted table is used for the encoding of the values in the at least one window; and writing each of the codes into a sequence into the recorder memory.
