Young people don't have to be nervous about tachycardia.

As we all know, the heart is an important organ of the human body. It is located on the left side of the middle part of the chest, with sternum and ribs in front and esophagus and spine in the back. It's about as big as your fist.

In one's life, the heart always works without sleep until the end of life. Because the heart is constantly contracting and relaxing, the blood in the blood vessels can flow continuously and people can survive. When the heart beats, the apex hits the chest wall, forming apex beating near the left nipple. People with thin figure and thin chest wall can clearly see or touch the heartbeat.

Under normal circumstances, the adult's heartbeat is between 60 and 80 beats per minute, but in a quiet state, if the heartbeat exceeds 100 beats per minute, it is "tachycardia", also known as "palpitation".

"Tachycardia" is not a disease name, but a symptom. The causes of tachycardia vary widely, the most common is the heart itself, such as various types of heart disease, myocarditis, heart failure and so on. Suffering from anemia, fever, acute and chronic infection, shock, hyperthyroidism, gas poisoning and other systemic diseases can also lead to tachycardia. Normal people take strong liquor, strong tea, strong coffee or smoke more, and take some drugs when they are exercising or emotional. , can speed up their heartbeat.

Why shouldn't young people be nervous about tachycardia?

Because the most common cause of tachycardia in young people is functional autonomic nervous disorder, which has been confirmed by more and more clinical cases and cardiologists.

Most young men and women suffering from palpitation were very nervous when they came to see a doctor, but after auscultation and general examination of related items, they found that all other examinations were normal except tachycardia. In addition to feeling flustered, patients often have neurasthenia symptoms such as dizziness, fatigue, insomnia and dreaminess.

Tachycardia is common among young people. According to the statistics of clinical data, it accounts for 16.8% of all adolescent patients, which is clinically called "adolescent tachycardia".

So, why are teenagers' autonomic nerves disordered?

Because adolescence is a transitional stage from basic maturity to full maturity. During this period, the youth's body and various important organs such as heart, lung, brain and reproductive organs are changing rapidly, and all these changes are dominated by the nervous system and endocrine system.

In the nervous system, there is an autonomic nerve whose center is not in the cerebral cortex, but in the hypothalamus under the cortex, so it is not dominated by human will. It goes without saying that autonomic nerve regulates the coordination and balance of sympathetic nerve and vagus nerve to adapt to the changes of external environment.

However, the autonomic nervous function in adolescence is generally unstable and prone to disorder or dysfunction. Tachycardia is due to the imbalance between sympathetic nerve (accelerating the heart) and vagus nerve (inhibiting the heart) under the command of autonomic nerve, and sympathetic nerve is dominant. In other words, the occurrence of tachycardia is mainly related to the decrease of vagus nerve tension and sympathetic nerve excitation. However, this is only a temporary obstacle and does not require special treatment. After puberty, palpitations will heal themselves.

Although adolescent tachycardia is not an organic disease, it is also very uncomfortable when the heart beats faster, especially when the heart rate exceeds 140 beats per minute. Therefore, when tachycardia exceeds 120 times per minute, you should take a proper rest and take some drugs to adjust the balance of autonomic nerves. /kloc-less than 0/20 times, generally do not need to rest, just use some medicine appropriately.

To sum up, young people should treat tachycardia correctly with an optimistic attitude of "magnanimous and carefree", and should not be burdened with thoughts for temporary puberty obstacles. They should study and work energetically and take part in various social activities and physical exercises. Practice has proved that proper activities and exercises can often relieve symptoms. Smoking, excessive drinking or drinking strong tea, coffee, etc. , often make the heart beat faster, so quit smoking and drinking, cheerful personality and regular life, which is the only way to cure tachycardia.
