What can be inferred about a rhythm with a consistent wide QRS and heart rate of at least 100 bpm?

A rhythm characterized by a consistent wide QRS complex and a heart rate of at least 100 beats per minute is indicative of Ventricular Tachycardia (VT). Ventricular Tachycardia is a condition where the electrical impulses in the ventricles fire off rapidly, leading to a fast heart rate with a wide QRS complex due to the abnormal pathway of electrical conduction.

The wide QRS complex in this case indicates that the depolarization is occurring in the ventricles rather than the usual pathway through the atria and ventricles, which involves the bundle of His and the Purkinje fibers. In VT, the ventricles beat independently and can do so at a rapid rate, which is why the heart rate is at least 100 bpm.

In contrast, other choices do not typically exhibit such wide QRS complexes. Atrial Flutter, for instance, presents with narrow QRS complexes and a characteristic "sawtooth" pattern of P waves. Sawtooth P waves suggest atrial activity rather than ventricular. Junctional Escape Rhythm is characterized by either normal or narrow QRS complexes and a slower heart rate, not exceeding 60 bpm.

Thus, the specific combination of a consistent wide QRS and
