Abstract Congestive heart failure (CHF) is a leading cause
of death in the United States affecting approximately
670,000 individuals. Due to the prevalence of CHF related
issues, it is prudent to seek out methodologies that would
facilitate the prevention, monitoring, and treatment of heart disease on a daily basis. This paper describes WANDA
(Weight and Activity with Blood Pressure Monitoring
System); a study that leverages sensor technologies and
wireless communications to monitor the health related
measurements of patients with CHF. The WANDA system
is a three-tier architecture consisting of sensors, web
servers, and back-end databases. The system was developed
in conjunction with the UCLA School of Nursing and the
UCLA Wireless Health Institute to enable early detection of
key clinical symptoms indicative of CHF-related decompensation. This study shows that CHF patients monitored by WANDA are less likely to have readings fall outside a
healthy range. In addition, WANDA provides a useful
feedback system for regulating readings of CHF patients.

Congestive Heart Failure (CHF, ) occurs when the heart
is unable to adequately supply enough blood for a healthy
physiological state. CHF typically occurs when cardiac
