A simplified device and method for continuous ECG monitoring incorporates electrodes in a pulse oximeter finger probe and/or in a blood pressure cuff. The electrodes in the pulse oximeter and blood pressure cuff generate a continuous ECG tracing without the use of disposable electrodes connected to multiple electrical wires in an ECG harness. In another embodiment, simplified ECG monitoring system can act as a secondary ECG input to a system that uses a primary ECG input as well.
