Summary
Self-injecting elemental mercury can lead to heart deposits, causing abnormal ECGs that mimic cardiac disease. This rare practice highlights the dangers of mercury and potential diagnostic confusion in clinical settings.
Area of Science:
- Cardiology
- Toxicology
- Diagnostic Imaging
Background:
- Self-injection of elemental mercury is a rare practice, sometimes associated with psychological distress or performance enhancement attempts.
- Intravenous mercury introduction can lead to systemic deposition, with the cardiovascular system being a potential target.
Observation:
- A 34-year-old male presented with acute chest pain and significant electrocardiogram (ECG) abnormalities.
- Initial investigations for cardiac causes were inconclusive.
- Radiography and cardiac ultrasound revealed metal-dense deposits within the heart.
Findings:
- The patient admitted to self-injecting elemental mercury 15 years prior to presentation.
- Deposited mercury in the right heart was identified as the cause of the cardiac abnormalities.
- The ECG changes were consistent with cardiac foreign body effects.
Implications:
- Elemental mercury deposition in the heart can cause ECG abnormalities mimicking primary cardiac conditions.
- This case underscores the importance of thorough patient history, including rare exposures, in diagnosing cardiac symptoms.
- Misdiagnosis can lead to inappropriate treatments and prolonged hospitalization for patients with a history of mercury self-injection.
