1. A computer implemented method, comprising: storing electroanatomic data in memory, the electroanatomic data representing electrical activity for an anatomic region within a patient's body; selecting a time interval for the electrical activity in response to a user selection, wherein the user selection specifies the interval based on interacting with a representation of a waveform of electrical activity for a given location of the anatomic region; and responsive to the user selection of the interval, generating a visual representation of physiological information for the user selected time interval by applying at least one analysis method to the electroanatomic data, the visual representation being spatially represented on a graphical representation of at least a portion of the anatomic region.
