# Dialysis-Reversible Complete Heart Block Without Severe Metabolic Derangements

## TL;DR

An elderly woman with chronic kidney disease experienced reversible complete heart block after dialysis, suggesting a dialysis-related cause.

## Contribution

This case highlights dialysis as a potential reversible cause of complete heart block in patients with chronic kidney disease.

## Key findings

- Complete heart block resolved after hemodialysis in a patient with chronic kidney injury.
- Heart block recurred after dialysis but resolved again following a second dialysis session.
- A permanent pacemaker was implanted following electrophysiology consultation.

## Abstract

We present the case of an elderly female who presented to the emergency department with dizziness. She was found to have an acute chronic kidney injury complicated by a complete heart block (CHB). She received a transvenous pacemaker and was taken for hemodialysis (HD) with complete resolution of her heart block. The following day, she was noted to be symptomatic and bradycardic. A repeat electrocardiogram showed a recurrence of the CHB. She was taken again for HD which led to the resolution of her conduction abnormalities. Electrophysiology was consulted and she had a permanent pacemaker implanted prior to being discharged.
