Sinus arrhythmia can be gastroscopically examined if there are no clinical signs, but gastroscopy is not recommended if accompanied by chest pain, chest tightness, shortness of breath, and other symptoms.
Sinus arrhythmia can be either a normal physiologic phenomenon or a pathology due to disease. If sinus arrhythmia does not have any symptoms of discomfort in the chest area, or the symptoms of discomfort in the precordial area appear after exertion or emotional excitement, and are relieved after resting for a few minutes, then the condition is relatively mild, and gastroscopy can be performed.
However, if sinus arrhythmia occurs, accompanied by chest tightness, chest pain and other symptoms, and can not be relieved for a long time, the condition is unstable at this time can not be carried out gastroscopy.
Therefore, if sinus arrhythmia occurs, it is necessary to perform a gastroscopy under the evaluation of a professional doctor.
