When I attended the recruitment physical examination, the doctor said that I had sinus arrhythmia. Does this have a big impact on the physical examination results? Male, 24 years old, his heart rate is 70 180cm 90kg, and he likes sports. Many people, especially young people, often get the diagnosis of "sinus arrhythmia" when checking ECG. Most people know that the heartbeat should be regular and tidy, so when they hear of "arrhythmia", many people think it is an abnormal phenomenon. Although there are no symptoms, you should seek medical advice everywhere and seek experts to cure the "disease" quickly. But doctors often say, "Don't treat it." These people are playing drums again. Are they incurable?

Actually, sinus arrhythmia is a normal physiological phenomenon, not a disease. "Sinus arrhythmia" is most common in children and adolescents, and it is not uncommon in adults.

The beating of a normal person's heart is commanded by a high-level command called sinoatrial node. Sinus node sends out signals to stimulate the heart to beat. This kind of heart beat caused by the signal from sinus node is called normal sinus rhythm, and its frequency is about 60- 100 times per minute. The number of beats per minute, that is, the heart rate, comes from this. But this frequency may be affected by many factors, even breathing.

Generally speaking, the heartbeat rhythm is regular and tidy. If the heart beats irregularly, we call it arrhythmia. From this point of view, "sinus arrhythmia" is the most common arrhythmia, which is caused by irregular signals from sinus node. But this kind of "arrhythmia" mostly belongs to "respiratory sinus arrhythmia", which is a normal physiological phenomenon. Its characteristic is that it changes with the change of breathing. When inhaling, the heart rate can be accelerated by several jumps, and when exhaling, it can be slowed down by several jumps. Its fast and slow cycle is exactly equal to a breathing cycle, and when you hold your breath, your heart rate becomes regular. This kind of "sinus arrhythmia" which changes with breathing is completely normal, so there is no need to worry or treat it.

Therefore, people diagnosed with sinus arrhythmia can pay attention to whether the acceleration and deceleration of their heart rate are related to breathing. As long as there are no other symptoms, you don't need treatment and you can engage in normal study and life.

Now many doctors have noticed the panic caused by sinus arrhythmia, so they will write "sinus rhythm" when diagnosing.

In addition, mental stress and other factors may also cause "sinus arrhythmia", which does not need treatment.
