Abstract
A pacing artifact detection apparatus and method uses a high bandwidth isolation amplifier having low harmonic distortion, high linearity, wide dynamic range, low current leakage, dc coupling, bipolar and high voltage isolation characteristics in conjunction with a high frequency operational amplifier to drive biopotential signals across an isolation barrier at high frequencies with no distortion. The speed of transmission across the isolation barrier is sufficiently high to allow diagnostics and analysis on the pacing artifact being transmitted across the isolation barrier without adversely impacting the reliability of the pacing artifact detection.
