What is Monomorphic Ventricular Tachycardia?
Monomorphic Ventricular Tachycardia (MVT) is a type of abnormal heart rhythm that originates in the ventricles of the heart. MVT is characterized by a regular, rapid heart rate that typically ranges from 120-250 beats per minute. The QRS complex on an ECG during an episode of MVT is typical of the same shape or morphology. MVT is often caused by structural heart disease such as ischemic or non-ischemic cardiomyopathy, or by certain medications or electrolyte imbalances.
MVT can be a life-threatening condition if not treated promptly and can lead to cardiac arrest or ventricular fibrillation. Treatment options may include anti-arrhythmic medications, electrical cardioversion to restore normal rhythm, or in some cases, an implantable cardioverter-defibrillator (ICD).
Difference Between Polymorphic and Monomorphic Ventricular Tachycardia
Polymorphic ventricular tachycardia (PVT) and Monomorphic ventricular tachycardia (MVT) are both types of ventricular tachycardia (VT), which is a fast heart rhythm originating from the ventricles. The key difference between PVT and MVT is that PVT is characterized by a constantly changing QRS complex, while MVT has a consistent QRS complex.
