What causes atrial rhythm?

Atrial rhythm is mainly due to abnormal sinus node function, unable to control the normal electrical activity of the heart, leading to the second pacemaker atrium to start working, through the atrium to control the rhythm. The

normal range of atrial rhythm is heart rate 60-100 beats/min, consistent with sinus rhythm. Heart rate is easily affected by environmental factors, exercise, etc., so heart rate is higher or lower than the normal range in a short period of time, and it can be relieved by itself. If the heart rate is abnormal for a long time, and there are chest tightness, palpitations and other symptoms, it is necessary to be alert to organic diseases.

Usually develop good living habits, such as regular rest, light diet, etc., to help maintain heart health.
