Overview
Some patients with bradycardia may have elevated/reduced concentration of electrolyte levels, glucose level, calcium level, magnesium level, thyroid function tests, toxicologic screen and troponin.

Recommendation for Laboratory Testing in Patients With Documented or Suspected Bradycardia or Conduction Disorders
| Class IIa |
| 1.In patients with bradycardia, laboratory tests (e.g., thyroid function tests, Lyme titer, potassium, pH) based on clinical suspicion for a potential underlying cause are reasonable.(Level of Evidence: C-LD) |
Laboratory findings
Laboratory findings consistent with the diagnosis of bradycardia include:[2]
- Electrolyte levels
- Glucose level
- Calcium level
- Magnesium level
- Thyroid function tests
- Toxicologic screen
- Troponin
