A system is described for allowing medical data obtained at a local site to be transferred to a data processing system located at a remote site. This medical data may include video data and/or data obtained from one or more medical devices such as a fluoroscopy device or an electrocardiograph (ECG) signal monitoring device. The data may be viewed on one or more display windows of the remote data processing system to allow a remotely-located expert to participate in an examination or medical procedure being conducted at the local site. In one embodiment, the remote data processing system also receives screen data from an implantable medical device programmer that is located at the local site. This screen data may include data associated with the configuration of the programmer, the configuration of an implantable medical device, and other information obtained from a patient such as physiological waveforms. Routing of all data may be performed by a communication hub operating as a stand alone device. Alternatively, the data routing function may be implemented on the programmer.

System and method for providing remote expert communications and video capabilities for use during a medical procedure

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.
