If a patient is currently in sinus arrhythmia, he or she can pass the physical examination because sinus arrhythmia is not caused by some disease, but is a physiological abnormality, such as deep inhalation during an electrocardiogram, which may cause sinus arrhythmia. In addition, some young patients are relatively prone to sinus arrhythmias, which are not triggered by some diseases. It is recommended that if you are concerned, you can combine this with an ambulatory electrocardiogram to assess the overall heart rate. Normally speaking the physical examination does not pass, it is likely that there is significant ischemia in the ECG, or significant tachycardia, or bradycardia, otherwise it is usually possible to pass.
