The ECG findings of hyperkalemia change as the potassium level increases, from slightly high levels to very high levels. The ECG findings include: Peaked T waves best seen in the precordial leads ...

Peaked T waves best seen in the precordial leads, shortened QT interval and, sometimes, ST segment depression. Widening of the QRS complex. This usually requires a potassium level of 6.5 or ...

In combination, these findings aroused the suspicion of hyperkalemia. Furthermore, the ECG software double-counted the QRS complexes, as it misleadingly counted T waves too (151 bpm; red box/arrow).

The investigational technology uses Lead I ECG data to alert patients and clinicians of moderate to severe episodes of hyperkalemia (excess potassium in the blood) that can lead to sudden cardiac ...

AccurKardia's AK+ Guard is designed to work with a wide range of FDA-cleared consumer and clinical wearables that currently capture Lead I ECG data (e.g., smartwatches), enabling hyperkalemia ...
