Abstract
Presentation: A Bolivian man in his 30s presented to the ED with non-exertional chest pain and intermittent second-degree atrioventricular (2:1) block.
Diagnosis: Given a history of untreated childhood Trypanosoma cruzi infection and family history of Chagas heart disease, late cardiac manifestation was suspected. Structural and ischaemic causes were excluded.
Treatment: Antiparasitic therapy was initiated. Pacemaker implantation was considered but deferred following shared decision-making due to absence of symptoms.
Discussion: Chagas heart disease (CHD) may present decades after infection with conduction abnormalities. Recognition in the ED is essential to enable appropriate management and reduce the risk of progression to complete heart block and sudden cardiac death.
期刊介绍：
Since its inception in 1867, the Journal of the Medical Association of Ireland and now in its present format, the Irish Medical Journal, has provided the medical community in Ireland with an invaluable service. As one of the leading biomedical publications in Ireland, it has sought to continue the education of medical students and postgraduates through scientific research, review articles and updates on contemporary clinical practices while providing an ongoing forum for medical debate. A measure of our stature is that we are listed in the Index Medicus and issued annually with a citation factor from the Institute for Scientific Information.
