Sinus arrhythmia. Arrhythmia? What's going on?

Arrhythmia generally refers to sinus arrhythmia. Sinus arrhythmia is considered to be caused by physiological factors, acute myocardial infarction, hyperthyroidism and other factors. The details are as follows:

1. Physiological factors

If the patient has long-term smoking, drinking, emotional agitation, strenuous exercise, etc., it may lead to vagus nerve excitation and sinus arrhythmia.

2. Acute myocardial infarction

When acute myocardial infarction occurs, the patient's myocardium lacks blood supply and necrosis, which may affect the normal beating of the heart and cause sinus arrhythmia.

3. Hyperthyroidism When

hyperthyroidism occurs, the thyroid gland often secretes a large amount of thyroid hormone, which increases the excitability of the nervous system and then causes sinus arrhythmia.
