What is Heart-Rate Variability Testing?

Heart-Rate Variability (HRV) testing is a non-invasive procedure that measures the variation in the time interval between each heartbeat, also known as the R-R interval. This variation is controlled by the autonomic nervous system (ANS), with the sympathetic and parasympathetic nervous systems playing dominant roles. During HRV testing, an electrocardiogram (ECG) is typically used to record your heart's electrical activity, capturing the timing of each beat. By analyzing the variation in these intervals, healthcare professionals can glean important insights about your overall health and wellness, particularly relating to your stress response and emotional health. HRV is a crucial biomarker as it can provide a snapshot of how your body reacts to stressors, how well you recover, and your overall cardiovascular health.

Why is your Heart-Rate Variability important?

Importantly, your HRV is a vital sign of the functionality of your autonomic nervous system and its two components – the sympathetic ("fight or flight") and parasympathetic ("rest and digest") systems. A healthy, high HRV score indicates a good balance between these two systems, which is crucial for maintaining homeostasis – the stable, balanced state needed for optimal body functioning. High HRV generally suggests a healthy heart that can efficiently adapt to changes in the environment and effectively respond to stressors. It's associated with better cardiovascular fitness, improved mental resilience, and lower risks of chronic diseases. On the other hand, low HRV can indicate chronic stress, fatigue, or poor cardiovascular health.


What are the symptoms of having a low HVR?

Symptoms of low HRV may not be immediately obvious as they can blend in with symptoms of stress and fatigue. These may include but are not limited to, difficulty sleeping, persistent feelings of stress, issues with digestion, frequent colds or infections (due to a weakened immune system), and in some cases, feelings of anxiety and depression. As we continue to invest in cutting-edge health technology like HRV testing at Nutritional Wellness Center, we can provide you with a more accurate, holistic picture of your health. By monitoring and improving your HRV, we can help optimize your health and longevity, emphasizing the prevention of imbalances that may contribute to disease.

What is the usual range of people’s HVR?

Heart rate variability (HRV) can vary greatly among individuals and is influenced by several factors such as age, fitness level, and health status. As a general rule, a high HRV is usually considered a good sign of heart health and autonomic nervous system balance, while a low HRV could indicate stress, illness, or overtraining. However, the specific numeric range for HRV is not standardized and can be measured in several ways. The most common measurement is the time gap between your heartbeats which varies each time your heart beats. This is measured in milliseconds (ms). For healthy adults, studies have shown a range from 20 to 60 ms, while elite athletes can have an HRV above 100 ms. For older adults, the range is often lower due to age-related decline in HRV.


Should I worry if my HRV is low?

While a low Heart Rate Variability (HRV) can sometimes be cause for concern, it's important to understand that it's not the only measure of health or fitness. HRV is merely one tool among many for assessing the state of your body's autonomic nervous system and overall well-being. A lower HRV may indicate a lack of adaptability or resilience to stress in the body. It could be due to factors such as physical illness, psychological stress, poor sleep, overtraining, or unhealthy lifestyle habits like poor diet or smoking. It may also be lower in individuals with certain health conditions, such as heart disease. However, a single low HRV measurement shouldn't be a cause for panic.
