Overview
Laboratory studies are especially important to exclude reversible causes of atrioventricular block, for example electrolyte imbalances and medications.
Laboratory Findings
- Serum levels of potassium, sodium and bicarbonates.
- Serum drug levels e.g digitalis.
- If acute myocardial infarction is the cause for current conduction disturbances, then troponin levels should be looked for.
- If thyroid dysfunction, infections or connective tissue disorders are responsible for heart block, then appropriate laboratory studies should follow.
