Resting Heart Rate and Heart Rate Variability (HRV): What’s the Difference? — Part 5, takeaways

Blog post by Marco Altini

In part 1 of this series, I covered the basic physiology of heart rhythm regulation. In part 2, I discussed the technology required for these measurements, why some sensors can be trusted, and why others can be used just for resting heart rate, and not for HRV. In part 3, we started looking at the data, with an analysis of population-level differences in resting heart rate and HRV. Finally, in part 4 we covered the most interesting aspect: individual-level data.
​
In this final part, I will report the main takeaways of the previous four parts, as a final wrap-up.
