Abstract
We attempted to construct ambulatory body surface isopotential maps of ST segment using our newly designed multi-lead ambulatory electrocardiograph. The multi-lead ambulatory electrocardiograph. The multi-lead ambulatory ECG system consisted of a commercially-available 4-channel recorder and a specially designed adapter, by which 30-lead ECGs were recorded together with body position signals for 24 hours. The electrode positions were selected from the 87 lead points for body surface mapping according to Yamada et al. Compensation for ST distortion and interpolation of ST level on time scale techniques were performed before the construction of ST maps. The extension and location of ST depression area thus obtained after compensation and interpolation were thought to be reasonable. In conclusion, the ambulatory recording of body surface ST maps is possible using our new device and may become useful for study of myocardial ischemia in daily life.
