Careful inspection of ECG tracings is essential to differentiate true ventricular fibrillation from artifacts, thereby avoiding unnecessary and potentially risky interventions.

May prompt closer ECG review during monitoring; leaves open the incidence and prevention of artifact-related VF misdiagnosis.
Polymorphic ventricular tachycardia and ventricular fibrillation (VF) carry important prognostic implications, especially in the post myocardial infarction period. However, artifact on the electrocardiographic tracing can mimic VF particularly on routinely recorded rhythm strips in hospitals. Such misinterpretation can lead to expensive (and potentially risky) diagnostic and therapeutic steps. We report on such a case and highlight the need for careful inspection of the tracing.
