Principal Investigator: Frederick Cobey, MD, MPH, FASE

This is a pilot/feasibility study on the accuracy of HRV measured by the Apple Watch on the clinical status of patients admitted for acute heart failure decompnsation. We hypothesize that there will be a statistically significant improvement in the HRV that correlates clinically over the course of hospitalization. Meaningful findings from this study will strengthen the potential for a telemonitoring system where HRV measured remotely from home using wearable devices like Apple Watch can help physicians monitoring their health and intervene accordingly.
