The above is a Holter examination of a patient referred for evaluation of occasional complaints of pulsed beats.

Holter analysis revealed bizarre wide QRS morphology which on initial examination suggested ventricular tachycardia [Figure 1]a-b. The patient was completely asymptomatic during the episode. The recording in channel 3 revealed a completely normal QRS pattern [Figure 1]c.
Figure 1: Showing recordings in Holter channels 1 (a), Channel 2 (b) and Channel 3 (c) respectively. Channels 1 and 2 reveal a bizarre QRS morphology suggestive of ventricular tachycardia. Simultaneous recording in Channel 3 reveal a completely normal QRS pattern. The normal spontaneous QRS hidden within the artifacts in Channel 1 and 2 are marked with arrows

ECG artifacts can be confused with supraventricular or ventricular arrhythmias which can occasionally lead to unnecessary investigations and injudicious therapeutic interventions.
