A method for coupling an ECG monitor with an incompatible ECG lead set includes the steps of providing an ECG adapter including an adapter body having at least one monitor connector adapted for coupling to an input of an ECG monitor and at least one lead set receptacle adapted for coupling to a connector of an ECG lead set incompatible with the input of the ECG monitor, coupling the at least one monitor connector of the adapter body with the input of the ECG monitor and coupling the at least one lead set receptacle of the adapter body with the connector of the ECG lead set to thereby electrically couple the ECG lead set with the ECG monitor.
