KEY Point: Knowing that the most commonly overlooked arrhythmia is AFlutter — suggests that the BEST way to avoid missing the diagnosis of AFlutter is simply to THINK of AFlutter whenever you have a regular SVT at a rate close to 150/minute ( in which you do not clearly see upright sinus P waves in lead II ).
