Key Points
- Review the diagnostic evaluation of broad QRS complex tachycardia to differentiate between ventricular and supraventricular origins and guide therapeutic management.
- Evaluation of electrocardiographic (ECG) criteria and signs used to distinguish ventricular tachycardia (VT) from supraventricular tachycardia (SVT).
- Analysis of ECG markers indicating the specific etiology and anatomical site of origin in the ventricles.
- Stable hemodynamic status during tachycardia does not exclude VT, and misdiagnosing VT as SVT carries severe risks when administering SVT-specific medications.
- ECG assessment enables the classification of broad QRS tachycardia, precise localization of ventricular origin, and identification of underlying etiology to guide prognosis and treatment.

IInterventionElectrocardiogram (ECG) evaluation for diagnosis and differentiation of ventricular tachycardia from supraventricular tachycardia
Familiarity with ECG signs to differentiate ventricular tachycardia from other broad QRS tachycardias is essential for correct treatment and prognostic evaluation.
