Abstract:
An apparatus for recording electrocardiographic data from a patient, comprising:an acquisition circuit operable to receive at least one electrocardiographic signal having a time-varying amplitude from the patient at a plurality of instants in time to produce samples and further digitizing the samples of the electrocardiographic signal to indicate the amplitude of the electrocardiographic signal at the plurality of instants to produce digitized samples; at least one memory operable to receive and store the digitized samples according to their associated sampling instants in time; and a processor communicating with the acquisition circuit and the memory to transfer the digitized samples from the acquisition circuit to the memory as a first task while executing a second task on a functionally concurrent basis, wherein the second task is selected from the group consisting of transmitting electrocardiographic data and setting user preferences.
