Wide complex tachycardia (WCT) is a rapid heart rhythm with broad QRS complexes on an ECG. It's a serious condition that demands prompt evaluation, as it can be life-threatening.
But what causes it? Ventricular tachycardia (VT) is the most common culprit, originating from the ventricles. However, supraventricular tachycardia (SVT) with aberrancy (altered conduction) can also present as WCT.
Differentiating between VT and SVT with aberrancy is crucial for proper management. Certain ECG features and clinical history can help clinicians make the right diagnosis.
Treatment depends on the underlying cause and the patient's stability. Unstable patients often require immediate cardioversion (electric shock). Stable patients may benefit from antiarrhythmic medications or other interventions. Don't ignore it! WCT needs immediate medical attention.
