A Study to Detect Hyperkalemia Using Smartphone-enabled EKG


About this study

The purpose of this study is to validate the real-world performance of our previously developed AI-ECG algorithm for identification of hyperkalemia with a six-lead mobile-enhanced device  

Ambulatory adult patients at increased risk for hyperkalemia due to age ≥ 50 years, and one or more criteria including eGFR (from serum creatinine) < 45 ml/minute and/or a history of serum potassium > 5.2 mEq/l, who present to the emergency department will be approached to consent for our rapid screening process.
