Signal processing circuitry 12 preferably includes a microcontroller, such as an Atmel Atmega 103 microcontroller, to take and collect physiological measurements and to amplify, filter, and signal process the analog data from the sensors, perform analog to digital data conversion at 10 bit accuracy using an on-chip ADC (with subsequent reduction for all but the ECG signal), and then format the data stream into a predetermined format for storage in memory/smart card 20 or for transmission by a PIC microcontroller (not shown) to a transmitter of the smart card 20 at an appropriate data bit rate. During normal operation, digital data is obtained from five channels of the ADC and the UART. A 10 bit ECG measurement is made of each of the leads of the ADC (corresponding to each of the ECG leads) every 4 msec. Preferably, a respiratory measurement and a battery voltage measurement are also made via the ADC every 4 msec., also at 10 bit resolution. However, only one reading of each of these parameters is needed every 40 msec; the remaining readings may be discarded. An external oximeter may provide a three byte measurement via the UART every second, only one byte of which is needed. In normal operation, the rate of data collection is therefore: 3×10×250=7500 bits/second ECG data; 2×10×25=500 bits/second for respiration and battery voltage data; and 1×8×1=8 bits/second oximetry data, for a total of 8008 bits/second.
