Heart rate is a synchronous contraction of the heart’s chambers to ensure blood supply throughout the body. Under normal conditions, a person does not physically experience a heart rate, which should average about 60-80 beats per minute. Depending on the level of stress, exercise, food, or medication, this value varies.
In today’s world, every second person uses smart bracelets to track their health. It is especially working for young people who follow a healthy lifestyle. During the morning run, the heartbeat will be frequent and physically palpable due to the heart muscle’s active contractions. But how will you understand the heart works in a state of rest? Heart rate is just one of many indicators of normal heart function.
Measurement of HRV and Heart Rate
The simplest way to get your heart rate yourself is to measure the pulsation on your wrist or neck. You should keep the account for a quarter of a minute. Then multiplied by four, or in 10 seconds, and multiply the result by six. It is a classic measurement method, but because the pulse is not the same for one minute, you need to count a full minute for a more accurate value. Due to physical and emotional stress, the heart rate increases. Diseases related to hemoglobin levels in the blood are also involved in increased heart rate above normal. Since the human body requires a more blood supply in such conditions, the heart reflexively responds with a greater frequency of contractions.
In any case, to quickly check the pulsation, you can download one of the profile applications. But heart rate is one indicator, and to properly assess your condition, you should use more advanced supplements that can determine heart rate variability, such as Welltory here. It is believed that the higher the heart rate at rest, the stronger the heart. But if the value exceeds 90 beats per minute, you should examine the work of your cardiovascular system. That is why the best blood pressure app will show you heart rate variability, blood pressure, stress levels, blood sugar, oxygen, etc. An analysis of your regular indicators’ complete map will help the doctor in diagnosing and prescribing treatment.
Heart Rate Variability (HRV)
What is HRV, and how does this interval indicator help you understand your health? The heart beats unevenly, so there is an interval between each subsequent beat, which is different each time. Most are accustomed to understanding the work of the heart as the vibration of a metronome. But this is not the case. Although the heart is an automatic pump, it is just as sensitive to your emotional and physical states. Its operation does not involve automatic uniform counting. In such stable conditions, a person could not adapt to change, strain, or relax, that is, live.
Heart Attack –
This indicator can predict a heart attack even in a person who has not previously had any mention of discomfort in the medical card’s heart area.
Stroke, and Diabetes –
An HRV below normal may indicate a predisposition to stroke, especially for diabetes and those who have already had it.
The intervals between heart contractions bilaterally affect sleep and its quality. That is why, by showing variability, we can talk about the quality of sleep, and at the same time, quality sleep improves this indicator.
Low variability may indicate depressive disorders, even in a physically healthy person.
Excessive exercise load directly reflects heart rate intervals. Overload reduces the effectiveness of training and benefits for the whole body. you can also use heart monitor watches to track your heartbeat while playing a sport.
A vast number of factors influence the variability index. Because of this, there is no single rule and algorithm for its decoding. Only an extensive database of research data, as the Welltory app work with, and a self-learning algorithm, allows you to get more accurate reports and analytics from the application.
Deeper Understanding of HRV
Cardiac variability demonstrates a person’s ability to switch between the parasympathetic and sympathetic nervous systems flexibly. That is, a higher rate of your HRV indicates the state of the autonomic system, which means more vital health and greater flexibility to life circumstances. Bilateral heart rate variability reflects the links with everything that improves resilience to stress. It suggests that poor quality sleep or blood pressure will reduce rhythm variability. Simultaneously, actions aimed at improving heart rate variability straight improve both sleep and blood pressure.
The relevance of tracking this indicator is that we know how to regularly improve cardiac variability, and hence everything that depends on it. That is, to improve your overall health, you should monitor your heart rate. But this requires an application that works on a logical and consistent analysis algorithm. The market range offers too many applications, which do not always monitor the necessary indicators.
In contrast to the variability of heart rate, which shows the time intervals between beats, the frequency demonstrates the sinusoidal nature of heart rate. Like the brain, the heart can generate many waves of different frequencies at the same time. The idea of measurement is to determine the dominant ones. For example, waves in the ultra-low frequency range of 0.003 Hz reflect very slow processes in the body, and therefore this frequency is recorded for 24 hours. The last mode of measurement gives the most complete picture of cardiac activity. Low-frequency waves with weak values in the range of 0.003-0.04 Hz indicate inflammatory processes, low hormone levels, and lack of tone. This is the most relevant indicator for modern diagnosis and, in practice, it is clear that these frequencies reflect the impact of reactions of the parasympathetic nervous system on the whole state of the body.
