1. A system for mapping gastric activity of a patient, the system comprising:
an electrode array patch having a plurality of electrodes configured to measure electrical signals associated with gastric activity of the patient; and
a processor configured to:
receive the measured electrical signals from the electrode array patch over a continuous time period of at least 2 hours;
concurrently receive patient symptom information over the entire continuous time period with the measured electrical signals;
determine one or more normalized biometrics over at least a portion of the continuous time period from the measured electrical signals;
correlating the one or more normalized biometrics and a symptom burden from the patient symptom information over the entire continuous time period;
determine a measure of correlation over the continuous time period;
determine a measure of temporal association in at least one time interval over the continuous time period between a gastric amplitude and at least one patient symptom information; and
determine a gastrointestinal phenotype of the patient based at least in part on the measure of correlation and the measure of temporal association; and
generate a report comprising at least the determination of the gastrointestinal phenotype.
