12. A method for low power operation of an electrocardiogram (ECG) recorder, the method comprising:
-
actuating a microcontroller for a first time period sufficient to write ECG data from a first-in-first-out (FIFO) memory to a flash memory; and
actuating the flash memory for a second time period sufficient to accept the ECG data, wherein the first and second time periods substantially coincide with each other, and the second time period is shorter than the first time period. - View Dependent Claims (13, 14, 15, 16, 17)
