Abstract

Laplacian electrocardiogram (LECG) locates the moment of activation (MOA) at an electrode site from the surface of the chest. A tripolar concentric ring sensor provides a small but well-defined localized signal. The instrumentation amplifier (IA) mounted above the sensor is powered by two on-board lithium batteries. Combining the common mode rejection (CMR) of the tripolar concentric ring sensor and the high common mode rejection ratio (CMRR) of the IA, the LECG signal can be obtained with a good signal to noise ratio (SNR) in real time. Different MOA were observed for each of the 16 sites for each subject. Beat to beat time shift changes were observed at the same site in one subject with bigeminal rhythm. Normal sinus rhythm (NSR) time delay pattern can be used to compare with abnormal ones. Fast arrhythmia classification can be classified in real time without digital signal processing.
