Sewer gas poisoning causing transient and focal ST-segment elevation in the ECG: Case report

Abstract

In India, a large number of sanitary care workers are involved in manual scavenging. This exposes them to sewer gas mainly consisting of hydrogen sulphide. Sewer gas toxicity primarily causes neurological injury, followed by cardiac and respiratory involvement. A few cases of diffuse ST-segment elevation in the electrocardiogram (ECG) following hydrogen sulphide poisoning are known in the literature. Here, we report a case of acute sewer gas poisoning in a 45-year-old man with transient and focal ST-segment elevation in the anteroseptal leads of the ECG mimicking acute anterior wall myocardial infarction.

A rare case of marsh gas poisoning-related myocarditis: critical role of cardiac MRI for diagnosis

“…Marsh gas poisoning is a rare cause of myocardial inflammation. 1 , 2 To the best of our knowledge, this is the first report in the literature demonstrating cardiac MRI findings in presumed marsh gas poisoning-related myocarditis. This report could potentially contribute to future clinical diagnoses.…”
