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 other tests are normal, they can be ignored.
Arrhythmia refers to the rhythm changes of atrium and ventricle caused by irregular excitation of sinoatrial node. Sinus arrhythmia is a kind of arrhythmia. Simply put, although the heartbeat starts to be normal, the heartbeat speed is obviously uneven. Sinus arrhythmia is not a single heart disease, but it is mostly a symptom caused by depressive heart disease, that is, chronic heart disease and subsequent heart disease will cause sinus arrhythmia.
The heart rate of normal people is called sinus rhythm, and the heartbeat range is between 60- 100. /kloc-more than 0/00 times is called tachycardia, and less than 60 times is called bradycardia. Normal sinus rhythm fluctuates evenly, and some patients' heartbeat is within the normal range, but arrhythmia will occur, that is, sinus arrhythmia. Sinus arrhythmia is more common in teenagers and belongs to the normal heartbeat range. Occasionally, slight sinus arrhythmia does not have much clinical significance to ignore. Obviously frequent arrhythmia needs to go to the hospital to check other heart problems.
