The most common measurements include the standard deviation of normal-to-normal intervals (SDNN), the square root of the mean squared differences of successive RR intervals (RMSSD), and the low-frequency (LF) and high-frequency (HF) power of HRV. SDNN reflects the overall HRV over a 24-...
WHAT’S THE NORMAL RANGE? High HRV indicates good fitness level and a healthy heart and nervous system. Low HRV is associated with stress, pain, heart disease and other pathologies. HOW CAN PETPACE HELP? Previously, measurement of HRV required Holter monitoring, which is clumsy and complex, ...
High HRV is usually a sign that: You have good cardiovascular fitness. You are resting and recovering well. You are currently more resilient to stress. Low HRV is usually a sign that: You had alcohol, a late meal, or exercised a few hours before bed. You are dehydrated, or your bedroom...

The Readiness Index categorizes into VERY LOW, LOW, NORMAL, and HIGH, mirroring deviations from your average HRV: VERY LOW– Significantly lower than usual (only 2-3% of your results). This indicates reduced parasympathetic nervous system activity, suggesting high stress or fatigue levels. ...
High HRV means your heart is responsive to the training program, and your body is ready to perform. Low HRV means your heart is not adapting, and your chosen training program may be too much or not enough for you. In athletestraining at high aerobic fitness levels, such as long-distance...
