Is ventricular tachycardia regular or irregular?

Ventricular tachycardia is typically characterized by a regular rhythm, but it's important to understand the nuances of this condition. Ventricular tachycardia (VT) is a type of supraventricular tachycardia (SVT) that originates in the ventricles of the heart. It is a serious condition that can lead to a life-threatening situation if not treated promptly. In VT, the ventricles beat at a rapid rate, often between 100 and 250 beats per minute. The rhythm is usually regular because it is a result of a single focus of electrical activity in the ventricles that is firing rapidly and consistently. However, there are different types of VT, and in some cases, such as polymorphic VT, the rhythm can be irregular due to varying electrical impulses. It's also worth noting that VT can sometimes be confused with atrial tachycardia, which is a different condition that originates in the atria and can present with an irregular rhythm if it is associated with atrial fibrillation or flutter. In summary, while ventricular tachycardia is generally regular, there are exceptions, and it is crucial for medical professionals to accurately diagnose and treat this potentially dangerous heart rhythm disorder.

If the rhythm pattern is irregular narrow-complex tachycardia, it is probably atrial fibrillation, possible atrial flutter, or multi-focal atrial tachycardia. Patient's rhythm has wide (> 0.12 sec) QRS complex AND Patient's rhythm is regular. Patient is in ventricular tachycardia or uncertain rhythm.
