For example, people with atrial arrhythmias might have atrial rates in the 200 to 300 beats per minute range.

例如，有房性心律失常的患者可能存在房性心律；房性心律每分钟在200-300次左右。

The atrial rate and ventricular rate are therefore identical.

因此，房率和室率是等同的。

The atrial rate is regular and rapid - between 250 and 400 beats per minute.

房率规则且快速--250-400次/分钟。
