Abstract
A pacing artifact detection apparatus and method uses high speed operational amplifiers configured as an instrumentation amplifier to sense common mode noise signals at frequencies up to and above 10 MHz. The common mode noise signals are eliminated from a patient's pacing artifact signal by driving the noise signals back onto the body of the patient.
