1. A method for displaying ECG signal data of a node of a patient, comprising:

  • detecting the ECG signal data with an ECG sensor component at least partially disposed in the patient, the ECG sensor component having a processor and being included in a catheter placement system;

    sampling the ECG signal data;

    identifying a first ECG waveform and a second ECG waveform from the sampled ECG signal data by the processor of the ECG sensor component;

    defining at least one parameter of a display window of the catheter placement system; and

    displaying the first ECG waveform and the second ECG waveform in the display window according to the at least one parameter of the display window, wherein displaying the first ECG waveform and the second ECG waveform includes;

    displaying (i) a first horizontal line that traces a peak of a P-wave portion of the first ECG waveform having a first amplitude; and

    (ii) a second horizontal line that traces a peak of a P-wave portion of the second ECG waveform having a second amplitude, the second amplitude being different than the first amplitude.
