Sinus Arrhythmia

Sinus Arrhythmia is a normal change in heart rate that increases slightly during inhalation and decreases during exhalation. Sinus arrhythmia is common in healthy people.

This type of arrhythmia is associated with breathing - the heart rate increases when you inhale and slows down when you exhale. This fluctuation in heart rate is considered normal, especially in children and athletes.

Sinus arrhythmia is caused by changes in the tone of the vagus nerve, which runs from the brain to the heart. When you inhale, the tone of the vagus nerve decreases, which leads to an increase in heart rate. When you exhale, the opposite happens - the tone increases and the pulse slows down.

Thus, sinus arrhythmia does not require treatment and is considered a benign condition. However, if there are significant fluctuations in heart rate, it is recommended to consult a doctor.

Arrhythmic sinus heart rate (ASHR) is a normal variation in heart rate that increases slightly with inhalation and decreases with exhalation. Although most people associate ASHP with abnormal heart rhythms and arrhythmias due to its name, it actually falls under the category of physiological fluctuations within the heart muscle and has little or no impact on the patient's health in most cases.

**Normal sinus rhythm**

Arrhythmic sinus rates occur in all healthy adults due to the autonomic nervous system. On average, in the adult population, ASHR is about 6 times per minute, significantly less than necessary for a normal pulse. This frequency of oscillations allows the myocardial muscle to relax and contract at the appropriate phase of the cardiac cycle. There is nothing in the body that can cause an irregular heartbeat as long as breathing remains normal. However, these rhythms can become stronger with intense physical activity, a slower heart rate, or extreme stress. Normal fluctuations in sinus rhythm under normal conditions occur 25-35 times per minute. If the pulse is less than 60-80 per minute, then we are talking about a very low pulse. For a typical healthy adult like you or me, it may be as low as 40 beats per minute during rest. This is because the low ripple state is an expected state in general for most healthy people. The norm is an increase in the frequency of sinus contractions during deep breathing, thus in the case of quiet breathing, the heart rate will average 50-60 beats per minute. Real indicators are less reliable and are not used in the field of sports and professional activities, where accuracy can affect the results and health of the patient.

A rarer option is

Sinus arrhythmia is a normal change in heart rate. It is characterized by a low heart rate when inhaling and a higher rate when exhaling. The syndrome is characterized by the absence of pronounced symptoms, but significantly worsens the quality of life of patients. Most often, arrhythmia is observed in young people under 30 years of age.

**Symptoms of sinus arrhythmia**

As a rule, this syndrome has a mild clinical picture. When the attack begins, the patient feels a “pushing” of the heart, weakness and pressing pain in the chest. In case of heart failure or concomitant chronic pathologies, attacks are characterized by shortness of breath and severe nausea, since the sufferer cannot fully absorb oxygen.

The syndrome occurs during physical overload, due to sudden nervous excitement or during excitement. For prevention, it is very important to monitor nutrition and sleep quality, avoid junk food and any nervous system stimulants. Yoga, swimming and therapy are especially effective in treating sinus arrhythmia.
