A low-cost high-efficiency fiber-optic coupler for recording action potentials within the myocardial wall.

Journal Article (Journal Article)

We present a high-efficiency, low-cost wavelength division multiplexer to record cardiac optical action potentials (APs) within the myocardial wall using optical fibers. APs with signal-to-noise ratio as high as 60, without spatial or temporal averaging, and as high as 200, with median-filtering, were recorded in rabbit ventricle.
