. "Arrhythmia" means that your heart rate is faster or slower than normal. Sinus arrhythmia mainly has two manifestations: one is sinus tachycardia, which is often caused by neurasthenia. Second, sinus bradycardia, the reason is not clear, but some professional athletes will have this phenomenon.

Medically speaking, sinus arrhythmia can be divided into two categories, one is respiratory and the other is non-respiratory. The former is mainly related to physiological changes, normal and does not need treatment. The latter appears in some heart diseases, accompanied by other changes in ECG, which is easy to find. Simple respiratory sinus arrhythmia is normal, but it can't replace all tests. If the other tests are normal, you can leave them alone.

Sinus arrhythmia means that the length of sinus cycle is different, and the difference between the longest cycle and the shortest cycle is more than120ms. Sinus arrhythmia is common in young people, especially when the heart rate is slow or the vagus nerve tension is high (for example, after taking digitalis or morphine). Sinus arrhythmia decreases with age.

Clinical manifestations:

Sinus arrhythmia has few symptoms, but sometimes when there is a long time difference between two heartbeats, it will cause palpitations.

Diagnostic basis:

1. ECG rhythm is sinus rhythm, that is, P wave is sinus P wave.

2. The difference between the longest peak-to-peak interval and the shortest peak-to-peak interval in the same lead is greater than 120ms.

Principles of treatment:

Sinus arrhythmia itself generally does not need treatment. After the activity, the heart rate increases and disappears.

Expert tip:

Sinus arrhythmia is common in young people and usually does not need treatment. After exercise, the heart rate accelerated and disappeared. For patients with symptoms, use drugs to increase heart rate, such as atropine and isoproterenol.

Medically speaking, sinus arrhythmia can be divided into two categories, one is respiratory and the other is non-respiratory. The former is mainly related to physiological changes, which is normal and does not need treatment. The latter appears in some heart diseases, and other changes accompanying ECG are easy to find. Simple respiratory sinus arrhythmia is normal, but it can't replace all tests. If the other tests are normal, you can leave them alone.

Arrhythmia should be distinguished from sinus arrhythmia and premature beats. Overall treatment should be based on comprehensive rest and emotional adjustment. You should avoid strenuous exercise, staying up late, strong tea and coffee, and low spirits. When the symptoms are serious, sedatives and cardiotonic drugs, such as diazepam and COQ 10, can be used appropriately.
