1. A system comprises: circuitry to receive information from a mobile device including ECG data representative of a beating heart; circuitry to analyze the ECG data using at least one pattern to detect a notable finding in the ECG data; circuitry to determine at least one additional pattern to send to the mobile device, based on the analysis of the ECG data, with a pattern comprising a specification of characteristics that is used by the mobile device and the circuitry to compare to incoming ECG data during analysis of the incoming ECG data; and circuitry to send the at least one determined pattern to the mobile device.
