1. A computer implemented method for monitoring a trend in heart failure (HF) progression, the method comprising:

  • sensing left ventricular (LV) activation events at multiple LV sensing sites along a multi-electrode LV lead, where the activation events are generated in response to an intrinsic or paced ventricular event;

    implementing program instructions on one or more processors for automatically;

    determining a conduction pattern (CP) across the LV sensing sites based on the LV activation events;

    identifying morphologies (MP) for cardiac signals associated with the LV activation events;

    repeating the sensing, determining and identifying operations, at select intervals, to build a CP collection and an MP collection;

    calculating an HF trend based on the CP collection and MP collection; and

    classifying a patient condition based on the HF trend to form an HF assessment.
