Which arrhythmia is indicated for a patient presenting with a wide complex tachycardia and regular rhythm?

The correct response refers to monomorphic ventricular tachycardia (VT), which is characterized by a wide complex tachycardia with a regular rhythm. In monomorphic VT, the QRS complexes are uniform and appear the same throughout the rhythm strip, indicating a consistent and stable source of electrical activity, typically stemming from a single area of the ventricles. This rhythm can often be diagnosed through an electrocardiogram (ECG), revealing a regular ventricular rate that is typically above 100 beats per minute, along with wide QRS complexes (greater than 120 milliseconds).

Understanding the nature of the arrhythmia is crucial for effective treatment. Monomorphic VT can be life-threatening and may require immediate interventions such as medication (like amiodarone) or electrical cardioversion, depending on the patient's hemodynamic stability and presentation. Proper identification of monomorphic VT allows clinicians to initiate the appropriate therapeutic approach to manage potential complications.

In contrast, polymorphic ventricular tachycardia exhibits varying QRS complexes that are not uniform, indicating a more unstable and possibly more dangerous rhythm often associated with conditions like Torsades de Pointes. Atrial fibrillation with a rapid ventricular rate typically presents with an irregularly irregular rhythm rather than a regular
