2022, American Journal of Emergency MedicineCitation Excerpt :While the EKG may not reliably predict hyperkalemia, the available evidence suggests that EKG changes may predict adverse outcomes from hyperkalemia, such as symptomatic bradycardia, ventricular dysrhythmia, cardiac arrest, or death. In the case series cited above, none of the patients with normal EKGs had severe adverse events [44-47]. In 2017, Durfey, et al. published a study evaluating the association between EKG findings and short-term adverse events in ED patients with hyperkalemia [55].
Can physicians detect hyperkalemia based on the electrocardiogram?
2020, American Journal of Emergency MedicineCitation Excerpt :However, the relationship between serum potassium and ECG manifestations is not clear [29-31] Acker et al. evaluated patients with serum potassium ranging between 6 and 9.3 mEq/L and found only 46% of ECGs had findings consistent with hyperkalemia, and no patient experienced serious arrhythmias [3]. Moreover, there are multiple case reports of patients with markedly elevated potassium levels, as high as 8.3 mEq/L without significant ECG changes [29,32]. Attempts to quantify ECG alterations associated with hyperkalemia by analyzing various ECG parameters (i.e. T wave amplitude, T-wave to R-wave ratio) have provided mixed results [30,33,34].
