Tremor Mimicking Ventricular Tachycardia on Telemetry.

A 79-year-old man with coronary artery disease and tremor-predominant Parkinson's disease underwent a gross total resection of a high-grade glioma and exhibited what appeared to be polymorphic ventricular tachycardia lasting 15-20 seconds on postoperative day 1. Further evaluation revealed that the patient did not have ventricular tachycardia, and that his abnormal telemetry signals were instead an artifact of his Parkinson's tremor. This case underscores the importance of considering tremor artifact when evaluating abnormal telemetry and electrocardiogram signals in patients with tremor, and highlights some features that can distinguish tremor artifact from a true arrhythmia.
