My high school classmate once suffered from sinus bradycardia, and I didn't know it until I fainted in the classroom and was sent to the hospital for examination. Later, we went to see her, and her doctor told us the symptoms of the disease. Let's share these symptoms with you.

What symptom does bradycardia have

Symptom 1: most patients with sinus bradycardia, especially those caused by nervous factors (increased tension of vagus nerve), have heart rate of 40-60 beats / min. due to little hemodynamic change, some people will have no symptoms

Symptom 2: bradycardia can reduce myocardial oxygen consumption, increase myocardial rest time, ventricular filling is good. The increase of cardiac stroke output can compensate for the decrease of heart rate, so the cardiac output per minute does not decrease. However, if the heart rate continues to slow down significantly and the cardiac stroke output cannot increase, the cardiac output per minute will decrease.

Symptom 3: cardiac output reduction will appear: shortness of breath, fatigue, dizziness, chest tightness and other symptoms. Severe syncope can occur, angina pectoris can occur in patients with coronary heart disease, which is more common in organic heart disease.
