b. Gradual alteration in the amplitude and direction of the QRS; atrial rate indiscernible, ventricular rate 150 to 250 beats/min
c. Regular ventricular rhythm with QRS complexes measuring 0.10 seconds or less; P waves may occur before, during or after the QRS; ventricular rate 41 to 60 beats/min

Characteristics of accelerated idioventricular rhythm:
Rhythm Ventricular rhythm is essentially regular.
Rate 41 to 100 (41 to 120 per some cardiologists) beats/min
P waves Usually absent or, with retrograde conduction to the atria, may appear after the QRS (usually upright in the ST segment or T wave)
PR interval None
QRS duration Greater than 0.12 seconds; the T wave frequently in the opposite direction of the QRS complex
