A body-surface electrocardiograph system employs unique spring-loaded metal-rod electrodes encased in metal housings to minimize set-up time and noise. 124 electrodes spaced at 35 mm intervals acquire body-surface potential with a 10 kHz sampling rate to capture and image (time sequentially) electrical activity of the heart not observable with standard 12-lead electrocardiography. Possible applications surveyed include assessing cardiopulmonary facility, examining age-related effects, and quantifying warning signs for myocardial infarction.
一种体表心电图系统采用独特的、装在金属外壳中的弹簧加载金属杆电极，以尽量减少设置时间和噪声。124个电极以35毫米的间隔排列，以10千赫的采样率采集体表电位，以便捕捉并（按时间顺序）成像标准12导联心电图无法观察到的心脏电活动。所调查的可能应用包括评估心肺功能、检查年龄相关影响以及量化心肌梗死的警示信号。
