Summary
The method of ECG-mapping is a high resolution ECG approach that has been demonstrated to provide additional information about the electrophysiological events in the heart. Multiple thoracic leads are recorded in order to analyze local potential changes on the body surface. Recent advances in electronic technology have enabled the development of practical clinical mapping systems. For the evaluation of body surface mapping in the clinical routine use we developed a completely self-contained clinical mapping system that contains all hardware/software components necessary for acquisition, processing, representation and documentation of surface maps. Amplifiers as well as microcomputer, floppy disk storage, printer and graphic CRT-terminal are mounted on a very compact trolley that can be easily wheeled to different measurement applications. In our system, 48 thoracic leads plus standard leads I, II, and III are sampled simultaneously using multiplexing techniques and direct memory access.
After preprocessing and automatic analysis the system provides comprehensive measurement reports, including plots of the representative complexes, printed values of the measured amplitudes and time intervals, graphs of the course of all computed parameters throughout the test etc. Using the described system we evaluated the diagnostic performance of ECG-mapping in comprehensive clinical studies.
