Roy is HRV Health’s founder. His RMSSD is between 100 and 120, and his RHR is usually around 40. Those are the metrics of an athlete in his twenties. Roy is . “Four years ago I was in deep trouble. My SRRS score was 394.” He says. “There was an 80% chance of having a… Continue reading Improving the numbers

Understanding the numbers
Getting familiar with all the metrics that HRV Health produces can seem daunting at first. What is good? What is bad? What should you be looking for? This article will answer those questions. RMSSD is the measure of heart rate variability (HRV). The higher the number, the better. A good number is age and gender… Continue reading Understanding the numbers
Measuring HRV
HRV results vary according to how and when they are measured. The “gold standard” for clinical HRV assessment is the 24 h HRV recording[1]An Overview of HRV Metrics and Norms with the subject linked to an ECG machine in a strictly controlled environment. These recordings achieve greater predictive power than short-term measurements. Although the mathematical formulas are the same,… Continue reading Measuring HRV
HRV and risk of severe COVID-19
A recent long term study[1]Underlying Medical Conditions and Severe Illness Among 540,667 Adults Hospitalized With COVID-19, March 2020–March 2021 from the CDC established that of the 540,667 of patients who were hospitalised, 94.9% had at least one underlying condition. Essential hypertension (50.4%), disorders of lipid metabolism (49.4%), and obesity (33.0%) were the most common. In a earlier… Continue reading HRV and risk of severe COVID-19
Using the Android app for the first time
The Android app is an integral part of the HRV Health platform. The app collects the interbeat interval (IBI) data from the Polar H10 heart rate monitor (HRM), and loads that data onto the platform. The platform and the app use the HRM device ID as the mechanism to uniquely identify the user’s data. So,… Continue reading Using the Android app for the first time

The benefits of measuring Heart Rate Variability
Heart rate variability gives users a daily measure of their health status. It also provides the elite athlete with a powerful metric of how their body is responding to training. A health heart is not a metronome[1]An Overview of Heart Rate Variability Metrics and Norms, even when the pulse rate is constant. The interval between… Continue reading The benefits of measuring Heart Rate Variability
Staying alive with HRV
Heart Rate Variability (HRV) reliably tests health conditions ranging from respiratory diseases and cardiovascular ailments[1]ANS Clinical Studies to COVID-19[2]Assessment of physiological signs associated with COVID-19 measured using wearable devices. HRV improves with increased levels fitness[3]Heart rate variability and aerobic fitness. HRV declines with age[4]Short-Term Heart Rate Variability—Influence of Gender and Age in Healthy Subjects. It’s… Continue reading Staying alive with HRV
