Study Summary

This is a pilot/feasibility study on the accuracy of HRV as measured by the Apple Watch on heart failure patients who are admitted to the hospital with heart failure exacerbation. The primary aim is to observe a statistically significant improvement in the HRV of acutely decompensated heart failure patients upon discharge when compared to admission, implying the utility of HRV measured by Apple Watch as a monitor for cardiovascular health.

Primary Outcome

Standard Deviation of NN Intervals is a time domain heart rate variability parameter. The value upon discharge after medical management should be statistically greater compared to admission value.
