健常成人の Isointegral Map (area map) の性差および年齢差の分析値

Isointegral maps (area maps) were recorded for 262 normal adults aged 20 to 81, and sex and age differences in the maps were analyzed. Men showed significantly larger QRS, QRST and STT area maps than women in the region from the left anterior to the left lateral chest. Age differences in the STT and QRST area maps were observed in men but not in women: younger men had larger maps in the region of the left anterior chest when compared with older males.
