The patient’s medical history was significant for chronic obstructive lung disease, obstructive sleep apnea, type II diabetes mellitus, hypertension, hyperlipidemia, and major depressive disorder. The patient denied palpitations or light-headedness in the postoperative period. The patient reported a history of intermittent dizziness and falls over the preceding months. A telemetry strip that prompted the referral is shown in Figure 1. On examination, the patient was in no apparent distress. Her heart rate was regular without murmurs or gallops. Auscultation of lungs revealed normal breath sounds. She had a resting tremor in her right hand. There was no rigidity in any extremities, and the rest of the physical examination findings were normal. She was admitted to the cardiology service for management of new-onset atrial flutter. Serum chemistries (including potassium and magnesium) and complete blood cell count were within normal limits. A 12-lead electrocardiogram (ECG) was performed on arrival to the telemetry unit. It was determined that the ECG demonstrated artifactual waves, most prominent in the limb leads (Figure 2). It was determined that she had pseudoatrial flutter waves and she was subsequently discharged with an event monitor to determine the underlying cause of her falls.
