The management of ventricular dysrhythmia in aconite poisoning

AbstractIntroduction: Aconite poisoning is relatively rare but is frequently complicated by ventricular dysrhythmias, which may be fatal.Molecular basis of aconite alkaloid ventricular arrhythmogenicity: Aconite exerts its toxic effects due to the presence of an admixture of alkaloids present in all parts of the plant. The major target of these aconite alkaloids is the fast voltage-gates sodium channel, where they cause persistent activation. This blockade of the channel in the activated state promotes automaticity within the ventricular myocardium and the generation of ventricular arrhythmias.Aconitine-induced arrhythmias: Aconite alkaloids are known to cause many different types of disturbance of heart rhythm. However, this focused review specifically looks at ventricular rhythm disturbances, namely ventricular ectopy, ventricular tachycardia, torsades des pointes and ventricular fibrillation.Objective: The objective of this review was to identify the outcome of anti-dysrhythmic strategies from animal s...
