Pseudo-ventricular tachycardia mimicking malignant arrhythmia in a patient with rapid atrial fibrillation

Abstract

Artifacts can simulate arrhythmias such as atrial flutter, atrial fibrillation, and ventricular tachycardia. A case of pseudo-ventricular tachycardia is outlined in a patient with newly diagnosed atrial fibrillation, which made the diagnosis a special challenge. Characteristic signs of pseudo-ventricular tachycardia are described. This case reinforces the importance of recognizing artifacts to avoid unnecessary interventions, especially in the telemetry and critical care units.
