The present invention relates to electrocardiography and to electrode arrangements used in electrocardiographic monitoring devices, and is more particularly related to a pad or patch containing said electrodes which may be used to passively and non-invasively monitor electrical activity generated by a patient's heart from the surface of that patient's chest, and to a connector which allows for fast and simple connection between the pad containing said electrodes and the devices and equipment typically used to monitor and view electrocardiographic information.
