Interference of the monitored or recorded electrocardiogram is common within operating
room and intensive care unit environments. Artifactual signals, which corrupt the normal …

Electrocardiographic (ECG) artifact, a common nuisance, has a wide range of manifestations
with varying clinical significance. Beyond loose leads, motion artifacts and broken wires …

Atrial flutter (AF) is the second most common supraventricular tachyarrhythmia following
atrial fibrillation. We present an interesting case of a diagnostic challenge manifested as an …

Figure 1. A. 12-lead electrocardiogram (ECG) of a patient with Parkinson's disease. Note
'pseudo-flutter waves' in the inferior leads with a cycle length of 200 ms. In lead III, normal P …

Orthostatic tremor is a rare but disabling neurologic condition characterized by unsteadiness
when standing accompanied by rapid leg tremor and frequent falls. We present the case of a …

Interference of monitored electrocardiogram (ECG) is a common event in intensive care
units and operation theaters. Artifacts in the ECG tracing can resemble serious arrhythmia …

Electrocardiographic (ECG) artifacts may resemble ventricular tachycardia (VT), leading to
inappropriate therapies. Despite extensive training, electrophysiologists have still been …

Electrocardiographic (ECG) artefacts may closely simulate both supraventricular and
ventricular tachycardias. We describe a case initially diagnosed as rapid atrial fibrillation …

A 64‐year‐old man was evaluated by a rapid response team for altered mental status shortly
after an uncomplicated surgery. He was found to be hypotensive and bradycardic, and an …

Background Ingestion of cylindrical batteries is uncommon. Management can include
removal via upper endoscopy, surgical excision, or observation. This case demonstrates the …
