PhysioBank Signals

Under construction! Descriptions of many signal types are missing.

Signal names identify the digitized signals (time series) in PhysioBank data collections. Most collections contain records with more than one simultaneously sampled signal. Their names, which appear in the .hea files associated with most records, are displayed when using the PhysioBank ATM as well as many other PhysioToolkit applications.

A dictionary of annotations (local features within signals) is also available.

Classes of Signals

Signals in PhysioBank belong to one of these classes:
