ECG leads allow for connection between electrodes applied by the patient and various sensors and telemetry devices that allow for non-invasive monitoring of electrical impulses produced from the heart during a long period of time. Certain electrodes form part of two pairs and give two leads. Electrodes are typically self-adhesive pads with a conductor gel at the center. The electrodes attach to cables that connect to the electronic heart rate monitor or electrocardiograph.
