What are the basic causes of sinus bradycardia

Sinus bradycardia may be caused by physiological factors, vagus nerve center excitability increased, acute myocardial infarction, etc.

1, physiological factors in the

population at night sleep and their own athletes, sinus bradycardia may occur due to reduced heart pumping frequency.

2, vagus nerve center excitability increased

If the patient has meningitis, cerebral hemorrhage and other diseases to increase the pressure in the brain, easy to increase vagus nerve center excitability caused by sinus bradycardia.

3, acute myocardial infarction

patients due to myocardial oxygen deficiency, increased oxygen consumption and other reasons acute myocardial infarction, due to heart function decline can lead to sinus bradycardia.
