Patent ID: 8494621

Claim:
A medical device for receiving electrocardiographic signals from a patient and analyzing the signals to produce a diagnosis of patient condition, the medical device comprising: a plurality of ten or fewer electrodes for attachment to the patient in at least one of ten standard ten-electrode positions; an interpretation algorithm database comprising a plurality of interpretation algorithms, each algorithm in the plurality designed to produce the diagnosis of patient condition when applied to an electrocardiogram and each algorithm in the plurality corresponding to a combination of respective positions of the plurality of ten or fewer electrodes each in one of the standard ten-electrode positions; and a signal processor connected to the plurality of electrodes, the signal processor disposed for receiving electrocardiographic signals from each of the plurality of electrodes and generating a twelve lead electrocardiogram from the electrocardiographic signals; wherein the signal processor identifies the combination of respective positions of the plurality of electrodes, selects the corresponding algorithm from the interpretation algorithm database based upon the positions of the plurality of electrodes and uses the selected algorithm to analyze the twelve lead electrocardiogram.
