Cardiac arrhythmias, electrolyte abnormalities and serum cardiac glycoside concentrations in yellow oleander (Cascabela thevetia) poisoning - a prospective study.
Consumption of yellow oleander (Cascabela thevetia) is a popular method of intentional self-harm in South India. ⋯ Cardiac glycoside concentration at the time of presentation predicted the development of new-onset serious arrhythmias. Although serum potassium correlated significantly with cardiac glycoside concentration at admission and overall serious dysrhythmias, it did not predict the development of new-onset serious arrhythmia. On the whole, serious dysrhythmias were significantly associated with higher number of seeds ingested, hypotension at admission, PR interval prolongation, presence of digoxin effect in ECG, hyperkalemia and higher cardiac glycoside concentration. The independent determinants of mortality were larger number of seeds ingested and hypotension at admission. Cardiac glycoside concentration and hyperkalemia failed to be independent markers of serious dysrhythmias as well as mortality.
