Key Points

The aim is to describe the clinical presentations and cardiovascular effects of recurrent tetrahydrozoline poisoning.
Reported five individual cases of tetrahydrozoline toxicity
Evaluated cardiovascular effects, including hypotension and AV conduction abnormalities
Utilized telemetry for monitoring in affected cases
All cases exhibited delayed hypotension upon exposure to tetrahyrdrozoline
Atrioventricular conduction abnormalities were observed in all cases
Telemetry monitoring was necessary for prolonged cardiac evaluation

Abstract

Dear Editor,We would like to report five presentations of tetrahydrozoline toxicity, resulting in delayed hypotension and atrioventricular conduction abnormalities, requiring telemetry and prolonge...
