Primary hyperparathyroidism can cause significant bradyarrhythmia, a slow heart rhythm. This case highlights the importance of considering hyperparathyroidism in patients with unexplained bradyarrhythmia, even when initially misdiagnosed.
Area of Science:
- Cardiology
- Endocrinology
- Internal Medicine
Background:
- Bradyarrhythmia is often attributed to primary cardiac conditions.
- Hyperparathyroidism is a metabolic disorder rarely linked to cardiac rhythm disturbances.
Observation:
- A patient presented with symptoms suggestive of sick sinus syndrome.
- Initial diagnosis focused on a primary cardiac etiology for the bradyarrhythmia.
Findings:
- The patient's bradyarrhythmia was ultimately diagnosed as secondary to primary hyperparathyroidism.
- Correction of hyperparathyroidism resolved the cardiac rhythm issue.
Implications:
- This case underscores the need to investigate metabolic causes like hyperparathyroidism in bradyarrhythmia.
- Clinicians should consider broader differential diagnoses beyond primary cardiac conditions for rhythm abnormalities.
