Interface module for electrically connecting medical equipment
First Claim
1. An interface module for direct electrical connection between an ICU monitor and a temporary transvenous pacing lead, the module comprising:
- a housing;
a first electrical connector disposed on an exterior surface of said housing for mating with a respective electrical connector of a selected one of a plurality of sensing leads of the ICU monitor;
a second electrical connector for mating with an electrical connector of the temporary transvenous pacing lead, at least a portion of said second connector being disposed within said housing; and
a coupling circuit electrically connected between the first and second electrical connectors.

Abstract
A temporary transvenous pacing system for obtaining a graphical record verifying the placement of temporary cardiac pacing lead within the ventricular cavity of a heart and for intracardiac recordings for arrythmia diagnosis. The system includes a temporary transvenous pacing lead having a distal electrode which terminates in a standard connector. A physiological monitor includes sensing electrodes having at least one connector adapted for electrical connection to a body surface. An interface module includes connectors adapted to interconnect the pacing lead to the monitor, and a coupling circuit for conditioning the pacing lead signals for use by the monitor. The pacing lead signals are displayed on an oscilloscope screen of the monitor, whereby an attending physician may adjust the pacing lead position in response to the electrical waveforms so obtained.
