A plurality of sensors are disposed in and around the heart of a patient to collect data such as various electrical parameters, pressure parameters and temperature parameters. The data collected via the sensors may be organized and stored according to cardiac rhythm type. The organization of data according to cardiac rhythm type allows the patient's physician to be better able to monitor how the various parameters are related to the various cardiac rhythm types. In a typical embodiment, one or more of the sensors may be deployed on a single lead implanted in the heart.
