Optically Isolated ECG Amplifier with Baseline Stabilization.

reportActive / Technical Report | Accession Number: ADA096812 | Open PDF

Abstract:

An electrocardiographic ECG amplifier that is optically isolated and suitable for use in all environments has been developed and tested in 100 experiments involving immersed humans during exercise and rest. The amplifier has less than a 10 micro A current leakage and employs an improved surface electrode placement technique. The frequency bandwidth of the amplifier easily can be varied to yield the optimum signal fidelity and signal-to-noise ratio for a given monitoring situation. The system incorporates low-power integrated circuits, which facilitate construction, provide inherent high reliability, and increase the useful lifetime of the battery power pack.
