A. Artifact masquerading as monomorphic ventricular tachycardia. Close inspection reveals QRS complexes at the same rate as the preceding and
succeeding sinus rhythm “marching through” the abnormal period. This figure represents sinus rhythm with mechanical artifact. B. Artifact that may be
mistaken as ventricular tachycardia. Regular QRS complexes at 75 bpm are evident throughout the tracing, confirming the diagnosis of electronic artifact
to explain the rapid spikes. A, reproduced with permission from Knight BP, Pelosi F, Michaud GF, et al: Clinical Consequences of Electrocardiographic
