Summary	Spatial repolarization heterogeneity greater than normal may allow early diagnosis of coronary artery disease (CAD). Traditional 12-lead ECG has some limitations. This is a newly developed multichannel ECG (MECG) system, which could detect low-amplitude high-frequency potentialsrepolarization heterogeneity from the adjusted recording channelsderived data for early detection of CAD.
Scientific Breakthrough	Traditional 12-lead ECG has limitation to quantify QT dispersion due to its low spatial accuracy. We have designed a multi-channel ECG machine, which could derive 25 to 221 channel signals from adjusting the numberslocations of electrodes. The derived data such as smooth index of QT interval (kind of repolarization dispersion) could be used for early diagnosis of coronary heart disease.
Industrial Applicability	Techniques for diagnosing myocardial ischemia are important. Stress myocardial perfusion imagingcoronary CT angiography, due to its ionizing radiationhigh cost, cannot be widely used in routine examinations. Our newly developed real-time multi-channel electrocardiogram can provide derived data such as SIQTc (kind of repolarization dispersion) for early diagnosis of coronary heart disease.
