Lead Exposure as Cause of a Clinical Scenario of Cardiac Arrhythmias





Arrhythmias, Cardiac/chemically induced, Lead Poisoning, Occupational Exposure


The recycling of used batteries has raised public health concerns as this activity is associated with occupational and environmental exposure to lead. We describe the case of a 26-year-old woman who experienced palpitations associated with headaches, fatigue and insomnia. Blood tests showed anemia (Hb 11.9 g/dL) and a lead concentration of 59 μg/dL. This was reported about four months after starting work in a battery recycling company. She left the company and, reported a gradual decrease in symptoms about one month later. The analytical study revealed a normalization of hemoglobin levels (12.2 g/dL) and a decrease in blood lead levels to 23.4 μg/dL. The health effects of lead exposure are nonspecific, and its diagnosis requires a high degree of suspicion. In this context, the collaboration between the Attending Physician and the Health and Safety Departments of companies is important.
