An ambulatory recorder having a volatile and a non-volatile memory is described. The recorder actively manages the transfer of the data in the volatile to the non-volatile memory. In particular, the sampling frequency and number of channels to be sampled are monitored. These parameters, along with the total buffer size available, are used to determine the final complete data set which can be stored in the buffer. Thereafter, the contents of the buffer are transferred to the non-volatile memory. In such a manner the recorder avoids filling the buffer in the middle of a sampling tick, in which case the remaining data to be sampled would be lost.
