The absence of P waves, wide QRS, rate >150, and the regularity of the rhythm indicate ventricular tachycardia. Atrial fibrillation is grossly irregular, has a narrow QRS configuration, and has fibrillatory atrial activity. Sinus tachycardia has Pwaves.
Ventricular fibrillation is irregular and does not have a consistent QRSduration.
