What is the heart rate of atrial fibrillation?

summary

With the increase of age, the incidence of atrial fibrillation is increasing, up to 10% of people over 75 years old. Patients without organic heart disease accounted for 3% - 11%. What is the heart rate of atrial fibrillation? Let's talk about it

What is the heart rate of atrial fibrillation?

Framingham study found that the mortality of patients with atrial fibrillation was 1.5-1.9 times higher than that of patients without atrial fibrillation. The occurrence of atrial fibrillation is related to age and the type of underlying diseases. Hypertension is the most common cardiovascular disease with atrial fibrillation. The risk of embolic complications in patients with atrial fibrillation is significantly increased. In order to better prevent and reduce the related complications.

The frequency of atrial activation in atrial fibrillation is 300-600 beats / min, and the heart rate is often fast and irregular, sometimes up to 100-160 beats / min, which is not only much faster than that in normal people, but also absolutely irregular, and the atrium loses its effective systolic function. The prevalence of atrial fibrillation is also closely related to coronary heart disease, hypertension and heart failure.

The duration of atrial fibrillation may be quite short at the beginning, but the onset time may be longer and longer, or even not relieved. Most of the attacks have no symptoms, sometimes patients will feel palpitations, fainting, dyspnea, chest pain.
