Clinical and electrocardiogram presentations of patients with high serum potassium concentrations within emergency settings: a prospective study

Common ECG interpretation software mistakes Part II: Computer errors that hide diagnostic clues

Electrocardiogram (ECG) interpretation software mistakes can lead to incorrect diagnoses and inappropriate treatments. Occasionally, however, repetitive and consistent computer errors may hide important clues for correct diagnoses that otherwise could have been missed. We present a collection of a few common and clinically important such peculiarities, and provide tools on how to prove or disprove the suspected diagnosis. In addition to the illustrations in print, an online supplement (OS) shows more examples of the discussed phenomena. In each ECG, the original computer interpretations were enlarged for legibility.

CE: Tumor Lysis Syndrome: An Oncologic Emergency

ABSTRACT

Tumor lysis syndrome is an oncologic emergency caused by the release of intracellular material, such as potassium, phosphate, and nucleic acids, into the bloodstream from the disintegration (lysis) of tumor cells. This condition, which is characterized by electrolyte imbalances, can be life-threatening, causing arrhythmias, seizures, acute kidney injury, and multiple organ failure. The prevention and treatment of tumor lysis syndrome requires immediate recognition of patients at risk for its development. With this knowledge, nurses can better manage and monitor treatments, thereby preventing complications and achieving better patient outcomes.
