HEART FAILURE PROGRESSION MONITORING BASED ON LV CONDUCTION PATTERN AND MORPHOLOGY TRENDS
First Claim
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.

Abstract
Computer implemented methods, devices and systems for monitoring a trend in heart failure (HF) progression are provided. The method comprises sensing left ventricular (LV) activation events at multiple LV sensing sites along a multi-electrode LV lead. The activation events are generated in response to an intrinsic or paced ventricular event. The method implements 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 and repeating the sensing, determining and identifying operations, at select intervals, to build a CP collection and an MP collection. The method calculates an HF trend based on the CP collection and MP collection and classifies a patient condition based on the HF trend to form an HF assessment.
