Cardiovascular Monitoring Using Multiple Sensors

A method comprising:

• receiving, from a first monitoring device coupled to a first body part of a subject, a first cardiovascular signal and a first motion signal indicative of one or more measurements obtained at the first body part;
• receiving, from a second monitoring device coupled to a second body part of the subject, a second cardiovascular signal and a second motion signal indicative of one or more measurements obtained at the second body part;
• filtering the first cardiovascular signal by removing one or more spectral components of the first cardiovascular signal that correspond to one or more spectral components of the first motion signal;
• filtering the second cardiovascular signal by removing one or more spectral components of the second cardiovascular signal that correspond to one or more spectral components of the second motion signal;
• identifying a correlated spectral component that is present in both the filtered first cardiovascular signal and the filtered second cardiovascular signal;
• and
• determining, based on the correlated spectral component, cardiovascular information of the subject.

A system comprising:

• a first monitoring device configured to couple to a first body part of a subject, wherein the first monitoring device is configured to measure a first cardiovascular signal and a first motion signal at the first body part;
• a second monitoring device configured to couple to a second body part of the subject, wherein the second monitoring device is configured to measure a second cardiovascular signal and a second motion signal at the second body part;
• and
• a controller configured to:
• receive the first and second cardiovascular signals and the first and second motion signals from the first and second monitoring devices;
• combine the received first and second cardiovascular signals;
• filter the combined cardiovascular signals by removing one or more spectral components of the combined cardiovascular signals that correspond to one or more spectral components of the first and second motion signals;
• and
• determine, based on a remaining spectral component of the filtered combined cardiovascular signals, cardiovascular information of the subject.
