Variable presentation of ventricular tachycardia-like electrocardiographic artifacts.
Diagnosis of clinically significant ventricular tachycardia (VT) relies on accurate electrocardiogram (ECG) interpretation, in the context of a convincing clinical picture. ECG artifacts resembling VT are common and can be misleading. We present two instances of VT-like ECG artifacts, which demonstrate the variable presentation of such artifacts and highlight ways in which these ECG tracings can be distinguished from true VT.
