Multi-site cardiac rhythm monitoring via multi-channel SCG system and exercise-induced physiological analysis

1) The spatiotemporal disparities across MSCG channels indeed correspond to the distinct physiological activities of the underlying cardiac chambers. 2) Exercise-induced cardiac mechanical dynamics were spatiotemporally resolved monitored by the system, revealing quantifiable timing shifts in valvular events undetectable by single-channel approaches. 3) The finding of consistent timing shifts in the AC and MO feature points under post-exercise scenario obtained via multi-channel monitoring, which supports the non-invasive assessment of cardiac function under exertion and in pathological conditions involving altered ventricular dynamics.
