This statement is true. In 2:1 rhythm, every second atrial impulse is conducted to the ventricles, leading to a rapid atrial rate and a normal or above normal ventricular rate. In 2:1 block, every second atrial impulse is blocked from reaching the ventricles, leading to a normal atrial rate and a below normal ventricular rate.

With 2:1 Rhythm, the Atrial Rate Is Very Rapid and the Ventricular
