Treatment of Hyperkalemia-Induced-Cardiac-Arrest by Dynamic Electrocardiogram and Point-of-Care-testing Potassium: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Hyperkalemia is one of the more common acute life-threatening metabolic emergencies. Although only a small proportion of cases progress to cardiac arrest (CA), early detection and timely intervention often yield excellent outcomes. Dynamic and characteristic ECG manifestations combined with point-of-care testing (POCT) potassium management provide timely evidence for hyperkalemia treatment. Wide QRS complex rhythms blended with T waves are extremely high-risk signals for CA due to hyperkalemia. Case Presentation: We report a 68-year-old male patient who presented to the hospital with syncope. ECG findings included peaked T waves, loss of P-waves, sinoventricular conduction, and a wide QRS complex rhythm. Shortly after admission, the patient experienced CA. POCT potassium levels were 9.0 mmol/L. With the help of ECG and POCT potassium results, the patient achieved return of spontaneous circulation (ROSC) after 32 minutes of CPR without residual neurological deficits. Conclusion: This paper highlights the role of dynamic ECG monitoring and POCT potassium management in rescuing patients with lethal hyperkalemia.Through POCT potassium monitoring, identification of high-risk ECG signals, combined with effective pharmacological intervention and high-quality CPR, the success rate of rescue treatment can be significantly improved, and patient prognosis can be enhanced.
