1. An electrocardiogram sensor, comprising:
an analog processing component configured to process a signal comprising cardiac electrical activity;
a digitizer configured to create a digital representation of the signal;
a microprocessor, configured to:
receive the digital representation of the signal;
process the digital representation to determine at least one electrocardiographic feature and periods during which the digital representation of the signal represents artifact;
analyze the determined at least one electrocardiographic feature to determine at least heart rate; and
conditionally generate information packets having a plurality of different information types, the information packets having a respective information type conditionally dependent on at least the determined at least one electrocardiographic feature and the determined periods during which the digital representation of the signal represents artifact; and
a wireless communication device, under control of the microprocessor, configured to remain in a non-transmitting low power state without transmitting information packets for the periods representing artifact, and to enter a transmitting high power state for transmission of the conditionally generated information packets containing valid statistics for at least the heart rate, and subsequently revert to the low power state after transmission.
