To the Editor —10-Second ECG-Based RMSSD as Valid Measure of HRV

We thank Lombardi et  al1 for highlighting the relevance of our article2 in their editorial comment, but we strongly disagree with their conclusion that the results of our study based on short-term heart rate variability (HRV) are “difficult to interpret.” We initially shared the same skepticism and concerns regard ing the utility of ultrashort HRV measurements based on 10-second ECGs, which is why we set out to extensively test this in a validation study3 before using 10-second root mean square of successive differences (RMSSD) in our recent publication.
