A system to use in combination with an ECG signal acquisition system connected to an arrangement of electrodes on a subject is provided. The system can include an antenna system in communication with the ECG signal acquisition system, a location tracking system operable to track a direction and a location of the antenna system relative to a reference, and an interface connected in communication with the ECG signal acquisition system and the location tracking system. The interface includes an output indicative of a direction of a source of the noise signal detected by the antenna system. A filter reduces an effect of the noise signal on an acquired ECG waveform data received by the ECG signal acquisition system. |
