Abstract
A system including a process for enhancing detection of a pacing artifact in a patient having artificially paced myocardial contractions. The detection is accomplished by sensing seven EKG leads. Each lead provides a view of the heart from a different angle. The process relies on differentially amplifying the sensed pulses separately and passing the pulses through a filter. An algorithm is utilized to detect the noise level and the pacing artifact amplitude, and automatically select a proper trigger level. False pacing artifacts are eliminated by use of the software qualification. The principal is that if the hardware differentiator produces a signal due to noise or a pacing artifact, an interrupt is generated.
