Disclosed is an ECG electrode lead wire connector which provides improved electrical and mechanical coupling of the ECG electrode press stud to the lead wire, provides enhanced ergonomics to the clinician, and may alleviate patient discomfort associated with the attachment and removal of ECG leads. The connector may be engaged and disengaged with little or no force imparted to the patient or the ECG pad, which significantly minimizes the risk of inadvertent dislodgement of the pad. In one embodiment the disclosed connector provides a thumb cam lever (110) which affirmatively engages the press stud to the connector, and provides tactile feedback to the clinician that the connector is properly engaged. In other embodiments, the connector provides a pushbutton (410) to enable the clinician to easily engage and disengage the connector from the ECG stud. The disclosed connectors may also decrease clinician fatigue, and may provide more reliable ECG results.
