A set of precordial electrodes are pre-attached along a single electrical cord where the electrodes can adjust in separation distances to accommodate different sizes of patients without cord looping or tangling. The invention employs cord corrals that permit a distance between adjacent electrodes to be shortened or lengthened while organizing excess cord. By allowing the adjacent electrode connectors to be shortened or lengthened, the lead array of electrode connectors may be used on a variety of different patient demographics and body sizes. While the single electrical cord eliminates the need for individual attachment of each of the lead wires of each of the electrodes to the ECG monitor.

ECG electrode attachment device

An interface unit for epicardial pacemaking and telemetry monitoring connects a pacemaker and bedside monitor for simultaneous pacing during electrogram visualization using epicardial pacing leads. The interface unit provides an electrically insulating housing having single handed manual attachment of the epicardial leads and a retractable protective shroud extending over the epicardial leads. The interface unit further provides electrical connectors for selective attachment to the pacemaker and bedside monitor.

Electrical connector and cover for simultaneously connecting wires, bedside monitor, and temporary pacemaker

A connector block that permits simultaneous and continuous interconnection of the three leads of the epicardial pacing wires, the pacemaker, and the ECG monitor on clear separately labeled connectors is provided. Circuitry is provided that allows the display of epicardial signals on the telemetry unit, while still preserving the ability to pace the heart from the pacemaker. When pacing the connector block prevents excessive loading of the pacer signals by the ECG monitor and/or damage to the monitor by the high-voltage pacer signals. The connector block may be used universally on all monitors without the need for sophisticated understanding of the electrical characteristics of the ECG monitor or concern for damage or improper signal loading.
