Official title
Monitoring Heart Failure Patients Using Heart Rate Variability Measured by the Apple Watch
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
