But Google said that's good first thing in the morning (early afternoon; no need to be pedantic about this stuff) and you just know they can't be wrong.
Missed beats (heart block) needs to be evaluated, since there are two types, one of which is malignant.
There is no cutoff for HRV and it is not used by the clinical mainstream. However, you can look up age norms and if you're below the norm, that's not a good sign. Be aware that raw HRV parameters, such as rMSSD, are not normally distributed, so you need to use a log-normalized measure, like the readiness indices used by HRV apps and not all of them have great population data, especially for older age groups.
