Coordinating musculoskeletal and cardiovascular hemodynamics
First Claim
1. A method for coordinating cardiovascular pump timing with detected musculoskeletal pump timing to facilitate favorable cardiovascular hemodynamics in an individual, the method comprising:
- accessing ongoing signals from at least one musculoskeletal activity sensor positioned in or on an individual;
processing the accessed signals from the musculoskeletal activity sensor;
detecting from the processed signals that the individual is engaged in a rhythmic physical activity, the rhythmic physical activity having an associated musculoskeletal pump timing;
determining a target cardiovascular pump timing for the individual, which would achieve favorable cardiovascular hemodynamics during the rhythmic physical activity;
determining a target heartrate corresponding to the rhythmic physical activity;
determining whether an intrinsic heartrate of the individual is less than or equal to the target heartrate; and
when the intrinsic heartrate is less than the target heartrate, providing a pacing signal to the heart of the individual to pace the heart at the target heartrate and the target cardiovascular pump timing such that a maximal musculoskeletal pumping of blood occurs substantially during cardiac diastole.

Abstract
The present invention is generally directed to methods, systems, and computer program products for coordinating musculoskeletal and cardiovascular hemodynamics. In some embodiments, a heart pacing signal causes heart contractions to occur with an essentially constant time relationship with respect to rhythmic musculoskeletal activity. In other embodiments, prompts (e.g., audio, graphical, etc.) are provided to a user to assist them in timing of their rhythmic musculoskeletal activity relative to timing of their cardiovascular cycle. In further embodiments, accurately indicating a heart condition during a cardiac stress test is increased.

13. A method, for artificially pacing a patient'"'"'s heart, comprising:
-
detecting a recurrent aspect of a rhythmic musculoskeletal activity of the patient; determining a target heartrate for the detected rhythmic musculoskeletal activity; determining whether an intrinsic heartrate of the patient is less than or equal to the target heartrate for the rhythmic musculoskeletal activity; and when the intrinsic heartrate is less than the target heartrate, providing a pacing signal to the heart, wherein; the pacing signal causes heart contractions in a cardiac cycle to occur with a predominantly constant timing relationship with respect to the detected recurrent aspect of the rhythmic musculoskeletal activity, the detected recurrent aspect of the rhythmic musculoskeletal activity has a consistent timing relationship with a maximal musculoskeletal pumping during the rhythmic musculoskeletal activity of the patient, and the pacing, signal results in the maximal musculoskeletal pumping occurring, predominantly within a diastolic period of the cardiac cycle. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
