Leads and electrodes

MR cardiac gating uses a three-lead technique that consists of four electrodes and four lead-wires:

The white electrode/lead wire is positioned for the right arm.
The black electrode/lead wire is positioned for the left arm.
The red electrode/lead wire is positioned for the left leg.
The green electrode/lead wire is positioned for the right leg.

Electrodes are radio translucent pads attached to the patient’s skin to provide electrical current.

Leads are shielded wires used to conduct the cardiac electrical signal from the electrodes to your MR system.

Use these electrodes and leads:

ECG Gating Cable Indications for Use

The GE high impedance cardiac gating cable is designed for MR applications where cardiac gating is required to reduce motion and flow artifacts. The cable may be used in the presence of surface coils.

Warning

Do not use expired or dried electrodes. They do not properly conduct the signal, which can lead to image degradation, create intermittent triggering, and can cause burns to the patient.

Warning

Do not use waveforms for physiological monitoring. Patient condition may not be reflected, resulting in improper treatment.

Warning

Do not allow the ECG cable connector end to touch the patient; patient burns can result. Use a thermal resistant material or patient comfort pad to keep the connector end from touching the patient. See the figures below for proper positioning.
