Embodiment Construction

[0017] Congestive heart failure occurs when the heart is unable to pump at the level needed to provide adequate blood flow throughout the body. Heart failure does not necessarily describe only a condition in which the heart stops pumping, it also describes reduced heart performance. In some cases, people with heart failure can lead relatively normal lives. In other cases, a person with heart failure may require immediate medical attention such as hospitalization to avoid death.

[0018] Patients with a history or risk of congestive heart failure (CHF) may be monitored to determine one or more of a number of physiological values ​​such as fluid status, heart rate, rhythm, respiration rate, respiration volume, duration of activity, activity intensity and body posture. From the determined physiological values ​​the CHF status can be determined. For example, a reduction in the duration and intensity of a patient's activity may indicate a worsening CHF state. Multiple establish...

Abstract

Embodiments relate to devices and methods for monitoring, identifying, and determining risk of congestive heart failure (CHF) hospitalization. Methods include determining physiological values of a patient by electrocardiogram (ECG), bioimpedance, and 3-axis accelerometer, filtering the physiological values, comparing physiological values to baseline parameters and determining CHF risk. Devices include a 3-axis accelerometers, bioimpedance sensors, and an electrocardiogram, each capable of measuring patient physiological values, and one or more processors to receive the measured physiological values.

Description

technical background [0001] Many physiological parameters are measured in the medical industry for the diagnosis, treatment and monitoring of patients. Electrocardiogram (ECG) measurements can be used to determine physiological parameters such as heart rate and rhythm. Bioimpedance measurements can be used to determine physiological parameters such as fluid status, respiration rate, and respiration volume. Accelerometer measurements can be used to determine physiological parameters such as activity intensity, activity duration, and patient posture. [0002] Physiological parameters can be used to diagnose and / or monitor medical conditions such as congestive heart failure (CHF) during hospitalization and / or after discharge. However, the measured physiological parameters are not always reliable for the purpose of monitoring the CHF health status of patients. For example, heart rate measurements may be unreliable for CHF diagnostic purposes during irregular but potentially hea...
