“…However, this patient's serum sodium, calcium and magnesium levels were within normal limits. Junctional rhythm has been reported in the setting of hyperkalemia (6.5 mEq/L) with concurrent beta-blocker therapy, but our patient had neither been on AV node nor on beta-blocking agents [5]. Atrial bigeminy (and later quadrigeminy) in this patient is indicative of sinoatrial block allowing for a focus below the sinoatrial node to escape and allow for "escape capture bigeminy" seen in this patient.…”

The spectrum of electrocardiographic changes seen with hyperkalemia is known to progress gradually with increasing serum levels of potassium. Initial changes are limited to peaked T waves and QT shortening, which subsequently progress to prolonged QRS/QT intervals, and finally sinus arrest, sinus bradycardia and asystole. We report a unique case of severe sinus bradycardia with atrial bigeminy and junctional rhythm in the setting of moderate hyperkalemia, a rarely reported electrocardiographic finding.
