What effect does sinus rhythm have too fast

Sinus rhythm too fast may appear heart load increase, heart blood supply deficiency, increase myocardial oxygen consumption and other effects.

1. Heart load increase in

sinus rhythm too fast, the heart may need to contract frequently, so that cardiac function abnormal, resulting in increased heart load.

2. Insufficient cardiac blood supply

due to the patient sinus rhythm too fast, so that the heart systolic time becomes shorter, diastolic time decreases, resulting in insufficient cardiac blood supply, prone to angina pectoris, myocardial ischemia and other conditions.

3. Increase myocardial oxygen consumption

Patients during the disease, heart contraction frequency will gradually accelerate, resulting in increased myocardial oxygen consumption, but also affect the normal function of the heart.
