Summary

Mapping of the electrical activity of the heart started in the late 1870s and has evolved from indirect recordings with a rheotome by Engelmann to highly sophisticated direct recordings of cardiac potentials with multi-terminal electrodes. This chapter mainly focuses on direct recordings from the heart. Developments of cardiac mapping from the rheotome via the string galvanometer and cathode ray tube to computerized digital mapping systems will be followed, and focus will be directed to various aspects that are important for mapping procedures. The advantages and disadvantages of different recording modes will be addressed and the different types of information that are derived from electrograms will be discussed. Ways to obtain three-dimensional information from catheters or multi-electrode arrays will be reviewed, and various other techniques to obtain information about propagation and repolarization of the action potential from the heart are explained.
