Zusammenfassung:An endovascular navigation system and method are disclosed. The endovascular navigation system includes an elongate flexible member configured to access the venous vasculature of a patient, a endovascular electrogram lead disposed at a distal end of the elongate flexible member and configured to sense an endovascular electrogram signal of the venous vasculature of the patient, a processor and an output device. The processor is configured to receive the endovascular electrogram signal, to determine a peak amplitude of a P-wave in the endovascular electrogram signal, and to determine that the position of the distal end of the elongate flexible member is within a predetermined structure within the venous vasculature of the patient. The output device is configured to display a visual indication that the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient, where the visual indication is different from the endovascular electrogram signal of the venous vasculature of the patient.
