Careful evaluation of ECG recordings is essential to distinguish artifactual tachyarrhythmias from true arrhythmias, thereby avoiding unnecessary and potentially harmful interventions like ablation or ICD implantation.
Electrocardiographic artifacts may generate recordings mimicking supraventricular and ventricular tachyarrhythmias. This report describes the diagnostic challenge presented by Holter or loop recordings in two patients, one with pseudo-atrial flutter and the other with pseudo- -polymorphic ventricular tachycardia.

Barold et al. (2013) conducted a case report in Artifactual electrocardiographic tachyarrhythmias (n=2). Electrocardiographic artifacts was evaluated on Diagnostic accuracy of tachyarrhythmias. Electrocardiographic artifacts on Holter and loop recordings can mimic supraventricular and ventricular tachyarrhythmias, posing a significant diagnostic challenge and risking inappropriate treatments.
