[Description of a system for automatic analysis of ambulatory electrocardiography using a microcomputer].

An automatic ambulatory electrocardiogram analyzer was developed using a self-powered fast reader of FM recorded cassettes and a "general purpose" microcomputer with 640 Kbytes of RAM and 20 Mbytes of mass memory on hard-disk.

Reliability of the system was evaluated, when appropriate, using standard databases.
