Portable signalling unit for an EKG
First Claim
1. A portable unit for monitoring EKG functioning comprising,a terminal block having wire contact means connected to the block for terminating EKG leadwires from a subject to be connected to the leadwires,a signal transceiver housed in the block and communicating with said wire contact means, having means for encoding signals from the wire contact means for transmission to a remote EKG and having receiver means for decoding signals from a remote source associated with the EKG,a bidirectional communications channel connected to said signal transceiver on one end and having a remote second end connected to the remote source, the channel carrying signals in both directions therebetween,signal processor means connected to the EKG apparatus and to said remote second end of the communications channel for evaluating the quality of signals received from said transceiver.

Abstract
A portable leadwire signalling terminal is provided as an interface between an EKG base unit and a patient. The portable terminal includes a signal transceiver which transmits leadwire information to the EKG apparatus, as well as pushbutton information. The EKG unit sends back information suitable for a video display in the terminal. This information is indicative of noise on each leadwire, as well as whether a lead wire is disconnected.

4. A portable unit for monitoring EKG functioning comprising,
a video display including driver means for presenting information on the display, wire contact means proximate to the video display for terminating EKG leadwires from a subject to be connected to the leadwires, a signal transceiver means connected to the video display and connected to said wire contact means for sampling signals from said wire contact means and for encoding said sampled signals and having receiver means connected to said driver means for decoding signals from a remote source, a bidirectional communications channel connected to said signal transceiver on one end and having a remote second end, signal processor means connected to an EKG apparatus and to said remote second end of the communications channel for evaluating the quality of signals received from said transceiver and for returning to the transceiver signal quality evaluation information in said channel for display in said video display.
